A perspective on OoL from Dr. Edward T. Peltzer. Quotes following are interview excerpts.
_______
I did have many discussions with Miller and Bada on many subjects, but
the issues of pre-biotic chemistry and the origin of life were the most common. Both were excellent chemists. You could ask them about almost anything and they would have an answer or know where one could look to
find out. In some cases, I suspected they already knew, but wanted to
give me the experience of scouring the library to find out. One could
say that they taught me everything I new about prebiotic chemistry at
the time.
During his doctoral studies at the Scripps Institution of Oceanography (SIO), he was mentored by two luminaries in prebiotic chemistry: Stanley Miller, renowned for the Miller-Urey experiment simulating early Earth conditions, and Jeffrey Bada, an expert in the field of amino acid racemization and a prominent figure in the study of organic compounds in meteorites.
As for the various individual [OoL] theories, here are a few of the
fatal errors. Hydrothermal vents do not make organic compounds, they
destroy them.
Surface based synthesis might yield a few useful compounds, but many compounds with a diverse range of functionality are needed for the first organism. RNA is too unstable outside a living cell to offer much hope
of it doing anything in the pre-biotic soup if somehow it was formed
(which is exceptionally unlikely).
My least favorite theory among all the options is the lipid world.
Assuming that one could get a collection of similar chain length fatty
acids bonded to glycerol to make triglycerides (which itself is highly unlikely in the pre-biotic soup of randomly generated compounds), then
one could form an artificial vesicle (alternatively called a coacervate
or liposome) with a lipid bilayer film. What you then have is not much
more than a rCLsoap bubble.rCY There is no interior metabolism, no ion- transport pathways in the rCLmembranerCY; it is nothing more than a film- coated droplet. How it would acquire an internal metabolism, etc., is anyonerCOs guess. But guesses, as entertaining as they might be, are not a scientific explanation of how life arose abiotically.
Random undirected chemistry does not yield biopolymers. Organisms need proteins, DNA &/or RNA, polysaccharides, etc. These polymers are uniform
in that they are composed of a monomeric class of compounds bound
together in very specific ways: proteins are chains of amino acids
linked by peptide bonds; DNA & RNA are chains of nucleotides linked by phosphate bridges; polysaccharides (e.g., starch & cellulose) are chains
of glucose molecules linked by +#-(1,4) glycosidic bonds in starch
(amylose) and +#-(1,4) glycosidic bonds in cellulose. Random, undirected chemical reactions do not yield these pure polymers. Instead, they yield polymers formed by random condensations of whatever compounds are at
hand, producing high molecular weight compounds without a well-defined structure. Examples of this are fulvic and humic acids, melanoids, etc. Their structures are complex, involve monomers from a variety of
compound classes and without a common bonding pattern. As such, they
exhibit little to no biological activity and store no information.
The biggest challenge of all will be to convince the folks who dream up
the various theories for the origin of life to include the impact of competing reactions on their pathways as opposed to writing rCLjust so stories.rCY
The origin of homochirality (D-sugars, L-amino acids, etc.) has proved
to be a difficult problem to solve. The goal needs to be chiral purity otherwise just a single wrong isomer can completely foul the
functionality of the biopolymer (protein, DNA/RNA, etc.). Homochirality
is always up against racemization, the process by which chiral molecules
get mixed with their mirror images (enantiomers). Any such lack of
purity among chiral molecules is deadly to life. All three of the
proposed processes to achieve homochirality fail for such reasons.
First, they are slow and only achieve a partial enrichment of the
desired form. Second, racemization reactions work faster to undo this enrichment. What little progress is made is quickly lost. Third, the racemization rate increases with temperature. So, the condition needed
to speed-up other synthesis processes works against homochirality. The source of homochirality remains an unsolved mystery.
Another problem for abiotic synthesis is that some amino acids have two amino groups, and some have two carboxylic acid groups. This leads to
the possibility that the carboxlic acid group can bind with the wrong
amino group (or vice-versa) and thus branches can form in undirected syntheses. None of the proteins in living systems have rCLbranchesrCY as these would impair the proper folding of the proteins into the enzymatic active forms.
Meanwhile, there are competing reactions that destroy the sugars. We
have already seen that the Maillard reaction of amino acids with sugars yields a variety of melanoid products. And unless the environmental conditions are just right and the pH gets too high, the Cannizzaro
reaction will consume sugars in pairs yielding an alcohol and a
carboxylic acid. Moreover, high temperatures (like are found in
hydrothermal vents) will cause the sugars to dehydrate and char and,
yes, this does happen even underwater at high pressures. The principal products were intractable materials composed of melanoids, tars and
carbon soot around the electrodes. This was not the kind of materials biologists and chemists were looking for as they are not components of living organisms. Later it would be shown that the amino acids were
racemic, not the pure L-isomers used by living organisms. More recent analyses have revealed a total of about 50 different amino acids were formed, but only 20 are used by living organisms. So, while he did find amino acids, they were not solely the ones living organisms use. There
was a lot of chaff mixed in with the wheat. While Miller was very open
and straightforward about these problems, they tend to get over-looked
in origin-of-life discussions. There is a tendency to focus on the path
to life ignoring all the problems: the competing reactions and
sidetracks along the way. This was not MillerrCOs fault, but it is common behavior among those that argue for a solely naturalistic origin of
life, where it is assumed that time and rCLnatural selectionrCY will take care of all the problems.
Has my view on whether liferCOs emergence was a natural, unguided process shifted with time? Of course. One starts out young and na|>ve. I believed pretty much everything I read in books and was taught in class. But as I learned more, I developed a healthy skepticism and learned to think for myself. Not so much in high school, but more so in college and graduate school. It was all part of being a scientist: you learn to not always
take everything at face value. Instead, I learned to ask questions: Do
the conclusions fit the data? What is the evidence for this?

What good does the gap denial do for you?-a It only allows IDiotic
Biblical creationists to lie to themselves about reality.-a You know
this for a fact, so why keep up the IDiotic stupidity.-a It doesn't
matter how the origin of life occurred on this planet.-a Whatever
happened is not Biblical, so it does not support your Biblical
beliefs.-a Wallowing in denial is never going to support your religious
beliefs.-a That is why the other IDiots quit the ID scam.-a Why you
continue to go to the ID perps in order to be lied to is stupid and
dishonest.-a The only IDiots left after the bait and switch started to
go down were the ignorant, incompetent and or dishonest.-a Competent,
informed, and honest IDiotic creationists do not exist.-a The fact that
the bait and switch IDiotic scam still goes down on their own
creationist support base is proof of that.
You have to deal with the reality in which you have to deny the
science. -a-aNo matter what happened with respect to the origin of life
on this planet the Bible is wrong once again.-a The earth is not flat,
we do not live in a geocentric universe, and the earth is much older
than a few thousand years.-a The earth was known not to be flat since
before Christ was born.-a Geocentrism lost out centuries ago.-a YEC was
dead before Darwin came up with natural selection.-a Even Kelvin's
estimates were in the hundreds of millions of years.-a The actual
origin of life on this planet is not mentioned in the Bible, nor is
the evolution of that life over billions of years.-a The Biblical order
of the creation of life on earth is as wrong as the shape of the earth
and it's place in the universe.-a Nothing about nature will support
your Biblical beliefs.-a You have to acknowledge that nature is not
Biblical, and this fact does not matter for some reason when it is the
basis for your denial of reality.
Gap denial is never going to support your religious beliefs when the
god that fills the gaps is not Biblical.-a The Supreme court was
correct in their comments in scientific creationist gap denial.-a Just
because we do not currently understand something about nature, is not
any support for your religious beliefs.-a This is obviously the case
with gaps that need to be filled by gods that are not Biblical.
Ron Okimoto
Ron, this post is not about the Bible or any particular interpretation
of it. The interview cited is only science. Ironically, your bluster and misdirection serve to "deny the science".

I first heard of this group to my surprise in a book I was reading.-a I found E-S did carry it, and I have been trying to read the well over
3000 posts they carry to get a feel for what gets discussed here, and
the value of subscribing.-a The control documents explain the group as this:
"The newsgroup talk.origins is meant as a venue for discussion of the scientific, religious, and political issues pertaining to various
theories of the origins and development of life and the universe. Within such basic guidelines, wide-ranging discussions over a large number of topics are covered, all relating back to the main purpose of the group."
That sounded fine, so I started trying to catch up on posts.-a The
charter documents also claim that the discussion here is "(sometimes hot!)."-a That's also fine, as most of Usenet is nowadays.-a But after reading the reply above, I realized I could have written it myself. I've read almost the same thing over and over again in the posts I've read,
and I'm only a small way through them.
What I find interesting in the reply above is what appears to be this posters usual tactic of disregarding the issue and turning it into a religious attack.-a The original post by Mark had nothing to do with religion.-a It was from a scientist who has found some very real problems
in his years of work regarding Naturalistic OoL, even though he
initially began his adult life accepting most of the Darwinian Evolution
he was taught.-a Though he does speak of the very big problems science
has to overcome in OoL research, he is kind enough to offer an
explanation of how he thinks evolution minded scientists should proceed
in the future.-a Where progress might be found.-a He seems fairly
controlled and even-tempered, and certainly open-minded.-a Exactly what a good researcher should be.-a Peltzer gives example after example of naturalist failings, which the reply above completely ignores and goes
off on the usual rant.-a I don't find that unexpected, but I do find it rather boring and irrelevant.

Alas, at the risk of passing irrevocably through the gates of OldThank you for saying what needed saying. I acknowledge that RonO's
Fartdom, I have to inform you that talk.origins is a pale shadow of its >former self. The halcyon days of moonstones, the felt effect of gravity,
and woodpecker tongues are never to be revisited. So don't get your
hopes up.
You are correct that Ron tends to view everything through the lens of,
as he puts it, the ID scam. To give Ron his due, Mark E sometimes posts >material that doesn't contain overt religious assertion, but fear not: >they're almost certainly lurking just below the surface. The stuff above
is a fair example: Peltzer IS an accomplished chemist. But he's also an >IDist, and his testimony in Kansas really was (again Ron is correct
here) a God of the gaps argument.
One thing you might do, is look at the TO website (talkorigins.org).
It's not been updated since the Permian, but there are a bunch of
excellent articles there under "Post of the Month".
Now get off my lawn!

A perspective on OoL from Dr. Edward T. Peltzer. Quotes following
are interview excerpts.
_______
I did have many discussions with Miller and Bada on many subjects,
but the issues of pre-biotic chemistry and the origin of life were
the most common. Both were excellent chemists. You could ask them
about almost anything and they would have an answer or know where
one could look to find out. In some cases, I suspected they already
knew, but wanted to give me the experience of scouring the library
to find out. One could say that they taught me everything I new
about prebiotic chemistry at the time.
During his doctoral studies at the Scripps Institution of
Oceanography (SIO), he was mentored by two luminaries in prebiotic
chemistry: Stanley Miller, renowned for the Miller-Urey experiment
simulating early Earth conditions, and Jeffrey Bada, an expert in
the field of amino acid racemization and a prominent figure in the
study of organic compounds in meteorites.
As for the various individual [OoL] theories, here are a few of the
fatal errors. Hydrothermal vents do not make organic compounds, they
destroy them.
Surface based synthesis might yield a few useful compounds, but many
compounds with a diverse range of functionality are needed for the
first organism. RNA is too unstable outside a living cell to offer
much hope of it doing anything in the pre-biotic soup if somehow it
was formed (which is exceptionally unlikely).
My least favorite theory among all the options is the lipid world.
Assuming that one could get a collection of similar chain length
fatty acids bonded to glycerol to make triglycerides (which itself
is highly unlikely in the pre-biotic soup of randomly generated
compounds), then one could form an artificial vesicle (alternatively
called a coacervate or liposome) with a lipid bilayer film. What you
then have is not much more than a rCLsoap bubble.rCY There is no
interior metabolism, no ion- transport pathways in the rCLmembranerCY; >>>> it is nothing more than a film- coated droplet. How it would acquire
an internal metabolism, etc., is anyonerCOs guess. But guesses, as
entertaining as they might be, are not a scientific explanation of
how life arose abiotically.
Random undirected chemistry does not yield biopolymers. Organisms
need proteins, DNA &/or RNA, polysaccharides, etc. These polymers
are uniform in that they are composed of a monomeric class of
compounds bound together in very specific ways: proteins are chains
of amino acids linked by peptide bonds; DNA & RNA are chains of
nucleotides linked by phosphate bridges; polysaccharides (e.g.,
starch & cellulose) are chains of glucose molecules linked by +#-
(1,4) glycosidic bonds in starch (amylose) and +#-(1,4) glycosidic
bonds in cellulose. Random, undirected chemical reactions do not
yield these pure polymers. Instead, they yield polymers formed by
random condensations of whatever compounds are at hand, producing
high molecular weight compounds without a well-defined structure.
Examples of this are fulvic and humic acids, melanoids, etc. Their
structures are complex, involve monomers from a variety of compound
classes and without a common bonding pattern. As such, they exhibit
little to no biological activity and store no information.
The biggest challenge of all will be to convince the folks who dream
up the various theories for the origin of life to include the impact
of competing reactions on their pathways as opposed to writing rCLjust >>>> so stories.rCY
The origin of homochirality (D-sugars, L-amino acids, etc.) has
proved to be a difficult problem to solve. The goal needs to be
chiral purity otherwise just a single wrong isomer can completely
foul the functionality of the biopolymer (protein, DNA/RNA, etc.).
Homochirality is always up against racemization, the process by
which chiral molecules get mixed with their mirror images
(enantiomers). Any such lack of purity among chiral molecules is
deadly to life. All three of the proposed processes to achieve
homochirality fail for such reasons. First, they are slow and only
achieve a partial enrichment of the desired form. Second,
racemization reactions work faster to undo this enrichment. What
little progress is made is quickly lost. Third, the racemization
rate increases with temperature. So, the condition needed to speed-
up other synthesis processes works against homochirality. The source
of homochirality remains an unsolved mystery.
Another problem for abiotic synthesis is that some amino acids have
two amino groups, and some have two carboxylic acid groups. This
leads to the possibility that the carboxlic acid group can bind with
the wrong amino group (or vice-versa) and thus branches can form in
undirected syntheses. None of the proteins in living systems have
rCLbranchesrCY as these would impair the proper folding of the proteins >>>> into the enzymatic active forms.
Meanwhile, there are competing reactions that destroy the sugars. We
have already seen that the Maillard reaction of amino acids with
sugars yields a variety of melanoid products. And unless the
environmental conditions are just right and the pH gets too high,
the Cannizzaro reaction will consume sugars in pairs yielding an
alcohol and a carboxylic acid. Moreover, high temperatures (like are
found in hydrothermal vents) will cause the sugars to dehydrate and
char and, yes, this does happen even underwater at high pressures.
The principal products were intractable materials composed of
melanoids, tars and carbon soot around the electrodes. This was not
the kind of materials biologists and chemists were looking for as
they are not components of living organisms. Later it would be shown
that the amino acids were racemic, not the pure L-isomers used by
living organisms. More recent analyses have revealed a total of
about 50 different amino acids were formed, but only 20 are used by
living organisms. So, while he did find amino acids, they were not
solely the ones living organisms use. There was a lot of chaff mixed
in with the wheat. While Miller was very open and straightforward
about these problems, they tend to get over-looked in origin-of-life
discussions. There is a tendency to focus on the path to life
ignoring all the problems: the competing reactions and sidetracks
along the way. This was not MillerrCOs fault, but it is common
behavior among those that argue for a solely naturalistic origin of
life, where it is assumed that time and rCLnatural selectionrCY will
take care of all the problems.
Has my view on whether liferCOs emergence was a natural, unguided
process shifted with time? Of course. One starts out young and
ve. I believed pretty much everything I read in books and wastaught in class. But as I learned more, I developed a healthy
skepticism and learned to think for myself. Not so much in high
school, but more so in college and graduate school. It was all part
of being a scientist: you learn to not always take everything at
face value. Instead, I learned to ask questions: Do the conclusions
fit the data? What is the evidence for this?

What good does the gap denial do for you?-a It only allows IDiotic
Biblical creationists to lie to themselves about reality.-a You know
this for a fact, so why keep up the IDiotic stupidity.-a It doesn't
matter how the origin of life occurred on this planet.-a Whatever
happened is not Biblical, so it does not support your Biblical
beliefs.-a Wallowing in denial is never going to support your
religious beliefs.-a That is why the other IDiots quit the ID scam.
Why you continue to go to the ID perps in order to be lied to is
stupid and dishonest.-a The only IDiots left after the bait and switch
started to go down were the ignorant, incompetent and or dishonest.
Competent, informed, and honest IDiotic creationists do not exist.
The fact that the bait and switch IDiotic scam still goes down on
their own creationist support base is proof of that.
You have to deal with the reality in which you have to deny the
science. -a-aNo matter what happened with respect to the origin of life >>> on this planet the Bible is wrong once again.-a The earth is not flat,
we do not live in a geocentric universe, and the earth is much older
than a few thousand years.-a The earth was known not to be flat since
before Christ was born.-a Geocentrism lost out centuries ago.-a YEC was >>> dead before Darwin came up with natural selection.-a Even Kelvin's
estimates were in the hundreds of millions of years.-a The actual
origin of life on this planet is not mentioned in the Bible, nor is
the evolution of that life over billions of years.-a The Biblical
order of the creation of life on earth is as wrong as the shape of
the earth and it's place in the universe.-a Nothing about nature will
support your Biblical beliefs.-a You have to acknowledge that nature
is not Biblical, and this fact does not matter for some reason when
it is the basis for your denial of reality.
Gap denial is never going to support your religious beliefs when the
god that fills the gaps is not Biblical.-a The Supreme court was
correct in their comments in scientific creationist gap denial.-a Just
because we do not currently understand something about nature, is not
any support for your religious beliefs.-a This is obviously the case
with gaps that need to be filled by gods that are not Biblical.
Ron Okimoto
Ron, this post is not about the Bible or any particular interpretation
of it. The interview cited is only science. Ironically, your bluster
and misdirection serve to "deny the science".

Alas, at the risk of passing irrevocably through the gates of Old
Fartdom, I have to inform you that talk.origins is a pale shadow of its former self. The halcyon days of moonstones, the felt effect of gravity,
and woodpecker tongues are never to be revisited. So don't get your
hopes up.
You are correct that Ron tends to view everything through the lens of,
as he puts it, the ID scam. To give Ron his due, Mark E sometimes posts material that doesn't contain overt religious assertion, but fear not: they're almost certainly lurking just below the surface. The stuff above
is a fair example: Peltzer IS an accomplished chemist. But he's also an IDist, and his testimony in Kansas really was (again Ron is correct
here) a God of the gaps argument.
One thing you might do, is look at the TO website (talkorigins.org).
It's not been updated since the Permian, but there are a bunch of
excellent articles there under "Post of the Month".
Now get off my lawn!

You have to understand the context and history around Mark's previous
posts on this subject.
OK, guess I will have to try and get more of the posts read here before coming to hard conclusions.
Anyone who knows anything about OOL know that there are major gaps in
scientific explanation of how OLL came about and indeed many
scientists think we will probably never find adequate answers. Mark
keeps pointing out these gaps without offering any suggestion as to
how they might be closed as if repetitively reminding us of the gaps
is significant progress in itself. The reality is that he is simply
reinforcing his own belief that these gaps somehow strengthen the case
for God.
I understand.-a I am not so much interested in the religious aspects of
the creation vs. naturalism debate here.-a It is pointless until you personally get to a conclusion of the actual origin debate.-a I want the science to help MY understanding of origins.-a If someone decides
naturalism doesn't work, it is another thing altogether to decide what
to do with that decision and how they move forward living.-a Yes,
religion can become part of the debate if you look at how you view the evidence and if it fits into say a Biblical context or a naturalistic context.-a For example the Young or Old Earth debates can make sense in
one area, and not so much in the other.-a The key for me is to simply not dismiss anyone's opinion simply because I look at things through a
different paradigm.-a I suppose on usenet that is often wishful thinking.
-aBut, this group in particular I hope will be a little less so, since I think most of the participants are a little better educated than the
average user.
I am a committed and practising Christian and I have many times
defended my beliefs in this group. The case for God, however, cannot
be based on gaps in scientific knowledge; it has to be based on
positive arguments about how belief in God deals with the stuff that
science *has* explained. Never mind, RonO and his obsession with ID,
as a committed Christian, I have challenged Mark to tackle this
question of how his understanding of God deals with this but he has
repeatedly declined to discuss it, insisting that the simple existence
of gaps is enough to show that God (aka the Intelligent Designer)
*must* have done it.
I would certainly agree with that.-a What interests me and my mostly layman's eye, are things that appear to be impossible from a naturalist perspective.-a Things that point for the need of information, things that appear irreducibly complex, etc.-a I'm sure I will probably ask questions
on some of the things I've found like this, but I think I should
probably try and read the post here first to not be redundant.
Anyway, thanks for your thoughts!

Okay, I'll give some you some points for the second one in particular.
However, elsewhere I have expanded and qualified this as follows:
___
If, after 500 years on sustained research into origin of life, all naturalistic avenues and hypotheses conceived to that point have been demonstrated to be inadequate, and this is the consensus a large
majority scientists in the field, would you say:
1. We may never work this out
2. Keep looking
3. Let's consider the "God hypothesis"
4. Other (please elaborate)
You may choose more than one option.
[From the subject /David Deamer's book "Assembling Life"/]

A perspective on OoL from Dr. Edward T. Peltzer. Quotes following are
interview excerpts.
_______
I did have many discussions with Miller and Bada on many subjects,
but the issues of pre-biotic chemistry and the origin of life were
the most common. Both were excellent chemists. You could ask them
about almost anything and they would have an answer or know where one
could look to find out. In some cases, I suspected they already knew,
but wanted to give me the experience of scouring the library to find
out. One could say that they taught me everything I new about
prebiotic chemistry at the time.
During his doctoral studies at the Scripps Institution of
Oceanography (SIO), he was mentored by two luminaries in prebiotic
chemistry: Stanley Miller, renowned for the Miller-Urey experiment
simulating early Earth conditions, and Jeffrey Bada, an expert in the
field of amino acid racemization and a prominent figure in the study
of organic compounds in meteorites.
As for the various individual [OoL] theories, here are a few of the
fatal errors. Hydrothermal vents do not make organic compounds, they
destroy them.
Surface based synthesis might yield a few useful compounds, but many
compounds with a diverse range of functionality are needed for the
first organism. RNA is too unstable outside a living cell to offer
much hope of it doing anything in the pre-biotic soup if somehow it
was formed (which is exceptionally unlikely).
My least favorite theory among all the options is the lipid world.
Assuming that one could get a collection of similar chain length
fatty acids bonded to glycerol to make triglycerides (which itself is
highly unlikely in the pre-biotic soup of randomly generated
compounds), then one could form an artificial vesicle (alternatively
called a coacervate or liposome) with a lipid bilayer film. What you
then have is not much more than a rCLsoap bubble.rCY There is no interior >>> metabolism, no ion- transport pathways in the rCLmembranerCY; it is
nothing more than a film- coated droplet. How it would acquire an
internal metabolism, etc., is anyonerCOs guess. But guesses, as
entertaining as they might be, are not a scientific explanation of
how life arose abiotically.
Random undirected chemistry does not yield biopolymers. Organisms
need proteins, DNA &/or RNA, polysaccharides, etc. These polymers are
uniform in that they are composed of a monomeric class of compounds
bound together in very specific ways: proteins are chains of amino
acids linked by peptide bonds; DNA & RNA are chains of nucleotides
linked by phosphate bridges; polysaccharides (e.g., starch &
cellulose) are chains of glucose molecules linked by +#-(1,4)
glycosidic bonds in starch (amylose) and +#-(1,4) glycosidic bonds in
cellulose. Random, undirected chemical reactions do not yield these
pure polymers. Instead, they yield polymers formed by random
condensations of whatever compounds are at hand, producing high
molecular weight compounds without a well-defined structure. Examples
of this are fulvic and humic acids, melanoids, etc. Their structures
are complex, involve monomers from a variety of compound classes and
without a common bonding pattern. As such, they exhibit little to no
biological activity and store no information.
The biggest challenge of all will be to convince the folks who dream
up the various theories for the origin of life to include the impact
of competing reactions on their pathways as opposed to writing rCLjust
so stories.rCY
The origin of homochirality (D-sugars, L-amino acids, etc.) has
proved to be a difficult problem to solve. The goal needs to be
chiral purity otherwise just a single wrong isomer can completely
foul the functionality of the biopolymer (protein, DNA/RNA, etc.).
Homochirality is always up against racemization, the process by which
chiral molecules get mixed with their mirror images (enantiomers).
Any such lack of purity among chiral molecules is deadly to life. All
three of the proposed processes to achieve homochirality fail for
such reasons. First, they are slow and only achieve a partial
enrichment of the desired form. Second, racemization reactions work
faster to undo this enrichment. What little progress is made is
quickly lost. Third, the racemization rate increases with
temperature. So, the condition needed to speed-up other synthesis
processes works against homochirality. The source of homochirality
remains an unsolved mystery.
Another problem for abiotic synthesis is that some amino acids have
two amino groups, and some have two carboxylic acid groups. This
leads to the possibility that the carboxlic acid group can bind with
the wrong amino group (or vice-versa) and thus branches can form in
undirected syntheses. None of the proteins in living systems have
rCLbranchesrCY as these would impair the proper folding of the proteins >>> into the enzymatic active forms.
Meanwhile, there are competing reactions that destroy the sugars. We
have already seen that the Maillard reaction of amino acids with
sugars yields a variety of melanoid products. And unless the
environmental conditions are just right and the pH gets too high, the
Cannizzaro reaction will consume sugars in pairs yielding an alcohol
and a carboxylic acid. Moreover, high temperatures (like are found in
hydrothermal vents) will cause the sugars to dehydrate and char and,
yes, this does happen even underwater at high pressures. The
principal products were intractable materials composed of melanoids,
tars and carbon soot around the electrodes. This was not the kind of
materials biologists and chemists were looking for as they are not
components of living organisms. Later it would be shown that the
amino acids were racemic, not the pure L-isomers used by living
organisms. More recent analyses have revealed a total of about 50
different amino acids were formed, but only 20 are used by living
organisms. So, while he did find amino acids, they were not solely
the ones living organisms use. There was a lot of chaff mixed in with
the wheat. While Miller was very open and straightforward about these
problems, they tend to get over-looked in origin-of-life discussions.
There is a tendency to focus on the path to life ignoring all the
problems: the competing reactions and sidetracks along the way. This
was not MillerrCOs fault, but it is common behavior among those that
argue for a solely naturalistic origin of life, where it is assumed
that time and rCLnatural selectionrCY will take care of all the problems. >>>
Has my view on whether liferCOs emergence was a natural, unguided
process shifted with time? Of course. One starts out young and na|>ve.
I believed pretty much everything I read in books and was taught in
class. But as I learned more, I developed a healthy skepticism and
learned to think for myself. Not so much in high school, but more so
in college and graduate school. It was all part of being a scientist:
you learn to not always take everything at face value. Instead, I
learned to ask questions: Do the conclusions fit the data? What is
the evidence for this?

on- the-origin-of-life/
What good does the gap denial do for you?-a It only allows IDiotic
Biblical creationists to lie to themselves about reality.-a You know
this for a fact, so why keep up the IDiotic stupidity.-a It doesn't
matter how the origin of life occurred on this planet.-a Whatever
happened is not Biblical, so it does not support your Biblical
beliefs.-a Wallowing in denial is never going to support your religious
beliefs.-a That is why the other IDiots quit the ID scam.-a Why you
continue to go to the ID perps in order to be lied to is stupid and
dishonest.-a The only IDiots left after the bait and switch started to
go down were the ignorant, incompetent and or dishonest.-a Competent,
informed, and honest IDiotic creationists do not exist.-a The fact that
the bait and switch IDiotic scam still goes down on their own
creationist support base is proof of that.
You have to deal with the reality in which you have to deny the
science. -a-aNo matter what happened with respect to the origin of life
on this planet the Bible is wrong once again.-a The earth is not flat,
we do not live in a geocentric universe, and the earth is much older
than a few thousand years.-a The earth was known not to be flat since
before Christ was born.-a Geocentrism lost out centuries ago.-a YEC was
dead before Darwin came up with natural selection.-a Even Kelvin's
estimates were in the hundreds of millions of years.-a The actual
origin of life on this planet is not mentioned in the Bible, nor is
the evolution of that life over billions of years.-a The Biblical order
of the creation of life on earth is as wrong as the shape of the earth
and it's place in the universe.-a Nothing about nature will support
your Biblical beliefs.-a You have to acknowledge that nature is not
Biblical, and this fact does not matter for some reason when it is the
basis for your denial of reality.
Gap denial is never going to support your religious beliefs when the
god that fills the gaps is not Biblical.-a The Supreme court was
correct in their comments in scientific creationist gap denial.-a Just
because we do not currently understand something about nature, is not
any support for your religious beliefs.-a This is obviously the case
with gaps that need to be filled by gods that are not Biblical.

Ron, this post is not about the Bible or any particular interpretation
of it. The interview cited is only science. Ironically, your bluster and misdirection serve to "deny the science".

Two out of three ain't good.
Okay, I'll give some you some points for the second one in particular.
However, elsewhere I have expanded and qualified this as follows:
___
If, after 500 years on sustained research into origin of life, all
naturalistic avenues and hypotheses conceived to that point have been
demonstrated to be inadequate, and this is the consensus a large
majority scientists in the field, would you say:
1. We may never work this out
2. Keep looking
3. Let's consider the "God hypothesis"
4. Other (please elaborate)
You may choose more than one option.
[From the subject /David Deamer's book "Assembling Life"/]
___
My question then, is it reasonable, accurate and in good faith to
characterise this as "science doesn't know X therefore God"?
Moreover, from the thread "Surviving the Daily DNA Apocalypse":
How many times have we all been around the block on this fundamental question? A common position here is functionally ontological/
metaphysical naturalism. No matter how wide the "gap" may become, non- natural explanations will not be [allowed to be] considered. From "The Stairway To Life: An Origin-Of-Life Reality Check" (pp. 187-189):
Objection: Your argument is a plea to the rCLGod of the gaps.rCY Just because science doesnrCOt have all the answers doesnrCOt mean that we have to invoke God to fill the gaps.
Response: The entirety of this book seeks to provide a proper scope to
the rCLgap.rCY The Stairway to Life clarifies that the gap is not simply a missing puzzle piece or a set of unclear details. The gap is, in fact,
the entirety of the origin of life. And the gap is growing over time as
we learn more about the complexity of cells and as efforts to produce components of life via realistic prebiotic approaches fail. As we have mentioned, additional steps will be added to the Stairway to Life over
time. These steps will come from previously unexplored processes that
are required for life. For example, we mentioned in Chapter 17 that the current best approximation of a minimal cell that can reproduce
autonomously includes 493 genes [201]. This same report specifies that
91 of the 493 genes perform unknown functions. Therefore, about 20% of
the minimal genome codes for functions that we have not yet explored. Further, the genome is not the only information contained in life. We
are just beginning to explore other forms of information found in living organisms, such as the sugar code that encapsulates cells [226]. Future exploration in these areas will result in new steps in the Stairway to
Life and an ever-increasing rCLgap.rCY The emperor is not simply missing a lapel pin; the emperor has no clothes. Our conclusion that creative intelligence was essential to start life is based on what we do know,
not on what we donrCOt know. The arguments in this book do not take the following form: rCLNo one knows how life began; therefore, God did it.rCY Rather, the inference to the need for intelligence in the origin of life follows directly from what we do know about the requirements for life
and what we do know about chemistry, physics, thermodynamics, and
biology. Turning this objection around, choosing to maintain a belief in abiogenesis despite the absence of a reasonable approach to the Stairway
to Life is a rCLmaterialism-of-the-gapsrCY approachrCoi.e., rCLwe donrCOt know how
life began, but we know that only natural processes were involved.rCY

How do you reconcile your views with theism?-a You're effectively telling god what god can and cannot do.-a In my view, that means placing yourself above God, which demotes God to non-god status.

My question then, is it reasonable, accurate and in good faith toYes it is.-a God-of-the-gaps is just that no matter if the gaps are never going to be filled.-a No one expects to figure out how life actually
characterise this as "science doesn't know X therefore God"?
arose on this planet.-a The best that we can do without a time machine is figure out the most likely way that life arose, and it could have
actually arisen in a much more unlikely way.-a The first organic conglomerate that produced the first self replicating molecules might
have been created by a random asteroid impact instead of condensing in
some crevice somewhere.
Gaps like what caused the Big Bang may never be filled due to the singularity that we can't get past to see what existed before.-a Denton
is happy with using this gap because he can never be demonstrated to be wrong.
I was a genetics major as an undergraduate at Berkeley, and all the geneticists told me that genetics was over and that the future was
molecular biology, so I did my PhD in molecular genetics.-a During my graduate studies tools for genomic analysis like PCR and microsatellite genetic markers were created, and they had the promise of allowing the unsolved issues in genetics to be answered.-a I went back into genetics because the new technology was opening up a new frontier in genetics.
There was finally the possibility that things like why the infinite
allele model worked so well in quantitative genetics.-a Quantitative
genetic analysis was well worked out, but we didn't understand why it worked.-a I started my first post doc on looking for quantitative trait
loci (QTL) in 1992.-a I retired in 2024 and we still do not know why the infinite allele model works for quantitative genetic analysis.-a We can sequence whole genomes now, but somethings remain a mystery.-a You do not see the ID perps claiming that their designer is responsible for the
success of the infinite allele model in quantitative genetics.
My guess for why it works is that due to the fall off in increased
accuracy with the inclusion of more past generations of data (about 3
past generations are enough to use for things like BLUP (best linear unbiased prediction) is that linkage is the reason for the infinite
allele model working so well.-a Most of it may be apparent linkage and
not actual linkage on the same chromosome.-a We have found that an LD (linkage disequalibrium) of only 0.3 within a population is sufficient
to use markers spaced along the genome to improve the accuracy of
predicting the best breeding values for individuals.-a All the alleles segregating in the genome have a minimum linkage of 0.5 (you inherit
half of one parent's genome) in the first cross.-a Closely linked markers have a linkage close to 1.0.-a This means that the whole genome can be considered to have a quantitative genetic value due to hundred or
thousands of genetic variants in that genome, and these variants can be inherited together just by chance if they occur in the same individual
even if they are not linked.-a This would create pseudo haplotypes based
on the whole genome, and not just haplotypes of the same chromosomes. In
the first cross half the QTL segregate together in any individual. My
guess is that this would create close enough to an infinite number of
pseudo haplotypes of unlinked QTL.-a Half the sires genome is inherited
in the first cross, 25% in the next cross, but if we are talking genome equivalents (and things that sire is homozygous for) then all the
homozygous alleles (1 genome equivalent) is inherited among the progeny
of the first cross, half a genome equivalent in the second cross and 25%
in the third cross.-a Statistically these pseudo haplotypes could persist for multiple generations.-a Each individual starts with a new set of
pseudo haplotypes that add to the haplotypes due to actual linkage, so
you never see all the "alleles" possible in a single generation.-a There would be pretty much an infinite number of them.

My approach is to avoid conflating science and theology. Therefore, I generally discuss the science only. My theological beliefs are not
relevant to interpreting science.
All the same, I'm happy to discuss my faith and have done so here. So to reiterate my approach:
In my opinion, growing scientific understanding of the functional
complexity of even minimal life is leading to deepening problems with abiogenesis. As a consequence, consideration of a supernatural
explanation becomes increasingly warranted as a rational response to scientific evidence.
It's not an either/or; it's not a suggestion to abandon science. Keep
doing science, but don't rule out supernatural explanation. Moreover, do
so with these in mind:
- don't be too hasty to appeal to the supernatural -- that is the god- of-the-gaps error;
- recognise the boundary of science, i.e. that science cannot, by definition, tell us anything about a hypothesised supernatural cause.
Some will only consider natural explanations because science has no
access to the supernatural, or an erroneous belief that science is the
only possible source of knowledge. That's akin to a child putting their hands over their eyes and declaring you can't see them.

How is retirement treating you?
Based on your experience as described above (credit where due btw) I'dPopulation genetics is limited by the mathematical and simulation
be interested in your comments on mathematical vs simulation vs observe
and infer approaches the study of population genetics.
I've mentioned here previously a partially completed computer program to simulate a population of ~10,000 "genomes", subject to sexual
reproduction, with chromosomes, recombination and crossover, controlled randomisation, and mutations using various selection coefficient
profiles, etc. I've been curious to attempt to explore fixation, viable selection coefficient distributions, genetic load and so on.
Inconclusive so far, but the exercise has been an impetus to try and understand some of the principles involved. I plan to get back to it,Doing something like this right takes a lot of advanced modeling and
but further study of pop gen first would help verify my assumptions and modelling.
My initial approach was to start with a supposed selection coefficient distribution. The data I could find suggested some lethal (-1), some deleterious (-1 < x < near-neutral), many neutral or near-neutral (zero
or just under), and a small number beneficial (just above zero). Using
this, determine if the population grows or goes extinct through genetic load. However, I found it difficult to find definitive data, and so
instead flipped the approach to reverse-engineer a "break-even"
selection coefficient distribution.
One question that presents itself is how to model overall relative
fitness of an individual carrying multiple mutations. The simple
solution is to just add them together. Of course, in nature complex and dynamic non-linear effects apply, which are beyond a simple simulation. However, it seems to me that a well-constructed simulation could give a reasonably indicative picture.

I would agree with you Mark on this, with a caveat that obviously there
are two completely different world views in this discussion, and both
should be considered.-a The evidence can have completely different interpretations depending on which view you are using to analyze it.

Nobody wants to say religion has all the answers and science can be abandoned.-a I find it's quite the opposite and not only don't fear
science, I eagerly await new findings.-a Ignoring the suggestion that ID
is a possibility is not science, it is religion.
- don't be too hasty to appeal to the supernatural -- that is the god-
of-the-gaps error;
- recognise the boundary of science, i.e. that science cannot, by
definition, tell us anything about a hypothesised supernatural cause.
No, it certainly can't.-a But it strikes me as dishonest that the
naturalism die-hards attack so many things with this God of the Gaps rhetoric, when for example they've been unable to successfully answer
some real problems like with Big Bang theory and came up with the
Multiverse Theory.-a To me that's a parallel type of solution and similar
to what they accuse in the God of the Gaps attacks.
Some will only consider natural explanations because science has no
access to the supernatural, or an erroneous belief that science is the
only possible source of knowledge. That's akin to a child putting
their hands over their eyes and declaring you can't see them.
I don't care if there are people who dismiss anything they consider supernatural.-a It is quite an amazing and difficult thing to actually consider it might exist.-a As someone who does think this is designed, I find I certainly do have doubts and questions because it is such an incredible thing.-a Of course, thinking life arose on a non-living rock
is similarly incredible to me.-a I look for answers in science.-a Then I weigh the results and move on from there.-a I get the feeling the
naturalist community doesn't think we honestly look at things and just accept whatever our Theological doctrine tells us.-a Of course this is
not the case, but is ironically the exact thing they do, only in reverse.

Not so with supernatural causes.
This is a fundamental issue in this debate. Intending to be constructive
and open-minded, what if I frame it this way:
Separate from and prior to specific discussions about science, how do
you regard naturalistic vs supernatural* explanations of origins?
Do you regard one more likely or worthy of consideration that the other,
and why?
* The so-called "God hypothesis", which might be summaried as: A transcendent/supernatural agent (an unspecified God, intelligent
designer, non-material cause), involved in the origin and/or
organisation of the material universe.

geneticists told me that genetics was over and that the future was
molecular biology, so I did my PhD in molecular genetics.-a During my
graduate studies tools for genomic analysis like PCR and
microsatellite genetic markers were created, and they had the promise
of allowing the unsolved issues in genetics to be answered.-a I went
back into genetics because the new technology was opening up a new
frontier in genetics. There was finally the possibility that things
like why the infinite allele model worked so well in quantitative
genetics.-a Quantitative genetic analysis was well worked out, but we
didn't understand why it worked.-a I started my first post doc on
looking for quantitative trait loci (QTL) in 1992.-a I retired in 2024
and we still do not know why the infinite allele model works for
quantitative genetic analysis.-a We can sequence whole genomes now,
but somethings remain a mystery.-a You do not see the ID perps
claiming that their designer is responsible for the success of the
infinite allele model in quantitative genetics.
My guess for why it works is that due to the fall off in increased
accuracy with the inclusion of more past generations of data (about 3
past generations are enough to use for things like BLUP (best linear
unbiased prediction) is that linkage is the reason for the infinite
allele model working so well.-a Most of it may be apparent linkage and
not actual linkage on the same chromosome.-a We have found that an LD
(linkage disequalibrium) of only 0.3 within a population is
sufficient to use markers spaced along the genome to improve the
accuracy of predicting the best breeding values for individuals.-a All
the alleles segregating in the genome have a minimum linkage of 0.5
(you inherit half of one parent's genome) in the first cross.
Closely linked markers have a linkage close to 1.0.-a This means that
the whole genome can be considered to have a quantitative genetic
value due to hundred or thousands of genetic variants in that genome,
and these variants can be inherited together just by chance if they
occur in the same individual even if they are not linked.-a This would
create pseudo haplotypes based on the whole genome, and not just
haplotypes of the same chromosomes. In the first cross half the QTL
segregate together in any individual. My guess is that this would
create close enough to an infinite number of pseudo haplotypes of
unlinked QTL.-a Half the sires genome is inherited in the first cross,
25% in the next cross, but if we are talking genome equivalents (and
things that sire is homozygous for) then all the homozygous alleles
(1 genome equivalent) is inherited among the progeny of the first
cross, half a genome equivalent in the second cross and 25% in the
third cross. Statistically these pseudo haplotypes could persist for
multiple generations.-a Each individual starts with a new set of
pseudo haplotypes that add to the haplotypes due to actual linkage,
so you never see all the "alleles" possible in a single generation.
There would be pretty much an infinite number of them.

Population genetics is limited by the mathematical and simulation
Based on your experience as described above (credit where due btw) I'd
be interested in your comments on mathematical vs simulation vs
observe and infer approaches the study of population genetics.
analysis that they have been able to do.-a A lot was accomplished before
we had computers to play with, but even with computers population
genetics is still limited due to what is not understood about the
biology.-a It is still subject to GIGO (garbage in garbage out).
The basic underlying biology of qualitative genetics (Mendelian
inheritance) was worked out within a century of Mendel's mathematical approach.-a Chromosomes were discovered to behave in Mendelian fashion in meiosis (the production of sperm and egg) and we figured out what genes
were and that they had regulatory sequences.-a It made Mendelian genetics pretty much totally understood.
As I mentioned we still do not understand why the infinite allele model works so well in quantitative population genetics.-a It is a model that
was needed to facilitate computation so that we could actually produce
some answers, but everyone understands that there are a finite number of genes far fewer than anything close to infinite.-a The human genome might only have 15,000 coding genes, but as I also mentioned it looks like we
may not fully understand the biology, and the actual biology may make
the genome appear to generate a near infinite number of apparent
alleles.-a We haven't worked out all of the biology.-a We need to get a better understanding of how dominance and gene interactions really
affect the population genetics.-a Quantitative genetics currently do not have adequate means for the analysis of dominance and epistasis (gene interactions).-a Nearly all the papers looking for the effects of
dominance and epistasis in populations under selection conclude that the effects are minimal, but that is likely not true.
I've mentioned here previously a partially completed computer program
to simulate a population of ~10,000 "genomes", subject to sexual
reproduction, with chromosomes, recombination and crossover,
controlled randomisation, and mutations using various selection
coefficient profiles, etc. I've been curious to attempt to explore
fixation, viable selection coefficient distributions, genetic load and
so on.
Probably all such programs that track alleles and assign selection coefficients to alleles do not model how the genome actually evolves.
In reality selection coefficients and genetic load assignments have to change as the allele frequencies in the populations change, but we
currently do not have a good way to do that, nor can we predict which
ones need to change with time and allele frequency.
The selection coefficient of a specific genotype can be dependent on the allele frequency at another locus, so background genetics matter as well
as the environment.
Humans average a genetic load of 1.5 to 2.-a These are lethal
equivalents, so if you were homozygous for your genetic load you would
be dead.-a Drosophila studies indicate that over 50% of the genetic load
is due deleterious loci that are only 10% lethal or less when
homozygous.-a 10% lethal is just the percentage reduction from the
expected frequency of homozygotes in the population.-a So in test crosses where you expect 50% homozygotes you only find 45% homozygotes.-a The sporadic lethality of such homozygotes is likely due to environmental influence, interaction with other sublethals, or deleterious
interactions with normally non lethal variants segregating in the population.
How we calculate the lethal load and identify lethal loci is not that accurate, mainly due to gene interactions messing with identification
and quantifying the lethal load.-a There are multiple examples of a fully lethal recessive trait associated with one loci that when crossed into another genetic background is not lethal or incompletely lethal (only a fraction of the homozygotes die).-a Natural selection occurs in some
lines kept to carry recessive lethals so eventually the homozygotes do
not die.-a Other loci in the genome were selected that counteracted the lethality.
We also know that we have issues because of recombinant inbred lines.
You can take two to 6 highly inbred mouse lines that have all been
inbred long enough to be over 99% inbred (99% of the alleles are
identical by descent and homozygous).-a These lines can have been
selected to be more reproductively successful than wild-type (more
litters and more pups per litter).-a It could be claimed that the lethal load in these lines was zero.-a In the case of two inbred lines what they
do is cross them together and then backcross to one of the lines several times so that they start mating full sibs that have different parts of
the donor genome and subsequent inbreeding produces lines where 12.5% of
the donor genome is fixed (homozygous) dispersed around the genome. Each recombinant inbred line has a different 12.5% of the donor genome so you
can use around 20 recombinant inbred lines to genetically map variants
from the donor genome.-a The problem is that many of these recombinant inbred lines start to fail to reproduce enough progeny to maintain the recombinant inbred lines.-a It turns out that parts of the donor genome
has a lethal load when combined with the genetic background of the other highly inbred line.-a They lose the lines if they continue to inbreed
them, so they start maintaining the lines as inbred as they can make
them, but they remain heterozygous for parts of the donor genome.
This just means that all the simplistic models of assigning genetic load
and selection coefficients to genotypes are inadequate to model what actually happens.
Doing something like this right takes a lot of advanced modeling and
Inconclusive so far, but the exercise has been an impetus to try and
understand some of the principles involved. I plan to get back to it,
but further study of pop gen first would help verify my assumptions
and modelling.
My initial approach was to start with a supposed selection coefficient
distribution. The data I could find suggested some lethal (-1), some
deleterious (-1 < x < near-neutral), many neutral or near-neutral
(zero or just under), and a small number beneficial (just above zero).
Using this, determine if the population grows or goes extinct through
genetic load. However, I found it difficult to find definitive data,
and so instead flipped the approach to reverse-engineer a "break-even"
selection coefficient distribution.
One question that presents itself is how to model overall relative
fitness of an individual carrying multiple mutations. The simple
solution is to just add them together. Of course, in nature complex
and dynamic non-linear effects apply, which are beyond a simple
simulation.
However, it seems to me that a well-constructed simulation could give
a reasonably indicative picture.
dealing with biology that we haven't yet completely worked out.-a We know that things like gene interaction and dominance need to be in the
models, but we don't know how much, nor can we predict when these things
are factors.
I do think that evolutionary models need to deal with the genetic load
and inbreeding.-a I believe that the deleterious genetic load in the population is very important in maintaining genetic variation and
selection progress in a population.-a It may be a major factor in why populations fail, and why others take over.-a Why is the spotted owl currently being out competed by the midwestern subspecies when they
normally come into contact each warm interglacial period when Canada
becomes forested instead of being covered with ice.
The Wrangel Island mammoth went extinct due to inbreeding depression. We
can get ancient DNA samples and the ice age megafauna of past ice ages
were less inbred and more genetically diverse than the last couple of
ice ages.-a My guess is that the longer cold periods of the last half million years has allowed over selection for cold adaptation, and the variation that was needed to adapt to the warmer interglacial periods
was mostly lost.-a A couple papers have noted that more ancient
populations had more warm adapted variants segregating than the most
recent ice age populations.-a They had adapted to cooling conditions for
a couple million years, but had maintained the genetic variants needed
to deal with the warmer interglacial periods until this last cold
period.-a Even though the populations reexpanded during this last glacial period and their populations recovered to what they had been during
other glacial periods their genetics remained inbred.-a It seems that
fewer isolated populations survived to remix after their territories reexpanded to allow the previously isolated populations to come together
and restore genetic diversity to the species.-a My guess is that
inbreeding depression was a major cause of the extinctions of the mega
fauna when they were again isolated to small populations during the
current interglacial.
I was involved in the first genome variation analysis of the domestic chicken population.-a The paper was published in PNAS.-a With genetic markers spread across the genome we could estimate inbreeding levels for each population that we had included in the study.-a We could also
conclude that the commercial lines only had a minor fraction of the
genetic diversity found among the populations that we had tested.-a Some
of the commercial population were highly inbred (Fst over 0.8). Multiple breeder companies were involved in the study, but several of them
objected to the findings.-a We had an internal peer review that was more rigorous than any that I had previously been associated with. Everything
was cross checked and assumptions verified and or noted.-a In the end the results were just what they were, and several companies removed
themselves as authors on the paper.-a What we did not put in the paper (because the breeder companies did not provide the pedigree information)
was that the inbreeding levels were much lower than we expected them to be.-a It is well known that commercial breeders try to limit inbreeding
to less than 1% per generation in order to maintain genetic progress due
to selection, but some of the lines had been closed lines for over 50 generations, and we started with birds inbred due to being bred to a standard.-a Before the modern commercial breeding industry started in the 1950's nearly all breeders sold chickens bred to a physical standard
(the American Standard of perfection).-a The commercial industry started with birds like White Plymouth Rocks that had been bred to the standard since the 19th century.
Somehow commercial breeders had selected for heterozygousity within
closed lines under intense selection.-a Our birds were less inbred than
we expected them to be.-a My take is that we were able to detect
inbreeding depression (dominance and gene interactions) and were able to identify the least inbred (alleles identical by descent) sibs by phenotype.-a This means that nature can do the same thing.-a So
deleterious loci would be important in the selection and success of a population, and we do not have the tools to detect and quantify the dominance and gene interaction effects that are significant even though

PNAS paper, this became my 4th most cited publication, and was my second publication accepted as submitted without revision, probably, because we
had revised it and checked it out multiple times before submission: https://pubmed.ncbi.nlm.nih.gov/18981413/

So when a natural explanation for abiogenesis is found, God goes poof?
This is a fundamental issue in this debate. Intending to be constructive
and open-minded, what if I frame it this way:
Separate from and prior to specific discussions about science, how do
you regard naturalistic vs supernatural* explanations of origins?
Do you regard one more likely or worthy of consideration that the other,
and why?
* The so-called "God hypothesis", which might be summaried as: A transcendent/supernatural agent (an unspecified God, intelligent
designer, non-material cause), involved in the origin and/or
organisation of the material universe.

What *is* a "transcendent/supernatural agent"? In particular, how does
it differ from "unknown causes"?
The scientific objection to the supernatural has nothing to do with it
being supernatural. I have said before and say again that any scientist would be eager to investigate any supernatural being you plop on their
lab bench. The problem is not that they're supernatural, but that
they're impossible to say anything about, whether because they don't
exist, because they are defined to be ineffable, or both.
That said, we can tentatively rule out an intelligent designer because
we *do* know something about what intelligent works look like (albeit
out sample of types of intelligence are inadequate), and life does not
fit the pattern.

_______
I did have many discussions with Miller and Bada on many subjects, but
the issues of pre-biotic chemistry and the origin of life were the
most common. Both were excellent chemists. You could ask them about
almost anything and they would have an answer or know where one could
look to find out. In some cases, I suspected they already knew, but
wanted to give me the experience of scouring the library to find out.
One could say that they taught me everything I new about prebiotic
chemistry at the time.
During his doctoral studies at the Scripps Institution of Oceanography
(SIO), he was mentored by two luminaries in prebiotic chemistry:
Stanley Miller, renowned for the Miller-Urey experiment simulating
early Earth conditions, and Jeffrey Bada, an expert in the field of
amino acid racemization and a prominent figure in the study of organic
compounds in meteorites.
As for the various individual [OoL] theories, here are a few of the
fatal errors. Hydrothermal vents do not make organic compounds, they
destroy them.
Surface based synthesis might yield a few useful compounds, but many
compounds with a diverse range of functionality are needed for the
first organism. RNA is too unstable outside a living cell to offer
much hope of it doing anything in the pre-biotic soup if somehow it
was formed (which is exceptionally unlikely).
My least favorite theory among all the options is the lipid world.
Assuming that one could get a collection of similar chain length fatty
acids bonded to glycerol to make triglycerides (which itself is highly
unlikely in the pre-biotic soup of randomly generated compounds), then
one could form an artificial vesicle (alternatively called a
coacervate or liposome) with a lipid bilayer film. What you then have
is not much more than a rCLsoap bubble.rCY There is no interior
metabolism, no ion- transport pathways in the rCLmembranerCY; it is
nothing more than a film- coated droplet. How it would acquire an
internal metabolism, etc., is anyonerCOs guess. But guesses, as
entertaining as they might be, are not a scientific explanation of how
life arose abiotically.
Random undirected chemistry does not yield biopolymers. Organisms need
proteins, DNA &/or RNA, polysaccharides, etc. These polymers are
uniform in that they are composed of a monomeric class of compounds
bound together in very specific ways: proteins are chains of amino
acids linked by peptide bonds; DNA & RNA are chains of nucleotides
linked by phosphate bridges; polysaccharides (e.g., starch &
cellulose) are chains of glucose molecules linked by +#-(1,4)
glycosidic bonds in starch (amylose) and +#-(1,4) glycosidic bonds in
cellulose. Random, undirected chemical reactions do not yield these
pure polymers. Instead, they yield polymers formed by random
condensations of whatever compounds are at hand, producing high
molecular weight compounds without a well-defined structure. Examples
of this are fulvic and humic acids, melanoids, etc. Their structures
are complex, involve monomers from a variety of compound classes and
without a common bonding pattern. As such, they exhibit little to no
biological activity and store no information.
The biggest challenge of all will be to convince the folks who dream
up the various theories for the origin of life to include the impact
of competing reactions on their pathways as opposed to writing rCLjust
so stories.rCY
The origin of homochirality (D-sugars, L-amino acids, etc.) has proved
to be a difficult problem to solve. The goal needs to be chiral purity
otherwise just a single wrong isomer can completely foul the
functionality of the biopolymer (protein, DNA/RNA, etc.).
Homochirality is always up against racemization, the process by which
chiral molecules get mixed with their mirror images (enantiomers). Any
such lack of purity among chiral molecules is deadly to life. All
three of the proposed processes to achieve homochirality fail for such
reasons. First, they are slow and only achieve a partial enrichment of
the desired form. Second, racemization reactions work faster to undo
this enrichment. What little progress is made is quickly lost. Third,
the racemization rate increases with temperature. So, the condition
needed to speed-up other synthesis processes works against
homochirality. The source of homochirality remains an unsolved mystery.
Another problem for abiotic synthesis is that some amino acids have
two amino groups, and some have two carboxylic acid groups. This leads
to the possibility that the carboxlic acid group can bind with the
wrong amino group (or vice-versa) and thus branches can form in
undirected syntheses. None of the proteins in living systems have
rCLbranchesrCY as these would impair the proper folding of the proteins
into the enzymatic active forms.
Meanwhile, there are competing reactions that destroy the sugars. We
have already seen that the Maillard reaction of amino acids with
sugars yields a variety of melanoid products. And unless the
environmental conditions are just right and the pH gets too high, the
Cannizzaro reaction will consume sugars in pairs yielding an alcohol
and a carboxylic acid. Moreover, high temperatures (like are found in
hydrothermal vents) will cause the sugars to dehydrate and char and,
yes, this does happen even underwater at high pressures. The principal
products were intractable materials composed of melanoids, tars and
carbon soot around the electrodes. This was not the kind of materials
biologists and chemists were looking for as they are not components of
living organisms. Later it would be shown that the amino acids were
racemic, not the pure L-isomers used by living organisms. More recent
analyses have revealed a total of about 50 different amino acids were
formed, but only 20 are used by living organisms. So, while he did
find amino acids, they were not solely the ones living organisms use.
There was a lot of chaff mixed in with the wheat. While Miller was
very open and straightforward about these problems, they tend to get
over-looked in origin-of-life discussions. There is a tendency to
focus on the path to life ignoring all the problems: the competing
reactions and sidetracks along the way. This was not MillerrCOs fault,
but it is common behavior among those that argue for a solely
naturalistic origin of life, where it is assumed that time and
rCLnatural selectionrCY will take care of all the problems.
Has my view on whether liferCOs emergence was a natural, unguided
process shifted with time? Of course. One starts out young and na|>ve.
I believed pretty much everything I read in books and was taught in
class. But as I learned more, I developed a healthy skepticism and
learned to think for myself. Not so much in high school, but more so
in college and graduate school. It was all part of being a scientist:
you learn to not always take everything at face value. Instead, I
learned to ask questions: Do the conclusions fit the data? What is the
evidence for this?

What good does the gap denial do for you?-a It only allows IDiotic
Biblical creationists to lie to themselves about reality.-a You know this for a fact, so why keep up the IDiotic stupidity.-a It doesn't matter how the origin of life occurred on this planet.-a Whatever happened is not Biblical, so it does not support your Biblical beliefs.-a Wallowing in denial is never going to support your religious beliefs.-a That is why
the other IDiots quit the ID scam.-a Why you continue to go to the ID
perps in order to be lied to is stupid and dishonest.-a The only IDiots
left after the bait and switch started to go down were the ignorant, incompetent and or dishonest.-a Competent, informed, and honest IDiotic creationists do not exist.-a The fact that the bait and switch IDiotic
scam still goes down on their own creationist support base is proof of
that.
You have to deal with the reality in which you have to deny the science.
-aNo matter what happened with respect to the origin of life on this
planet the Bible is wrong once again.-a The earth is not flat, we do not live in a geocentric universe, and the earth is much older than a few thousand years.-a The earth was known not to be flat since before Christ
was born.-a Geocentrism lost out centuries ago.-a YEC was dead before
Darwin came up with natural selection.-a Even Kelvin's estimates were in
the hundreds of millions of years.-a The actual origin of life on this planet is not mentioned in the Bible, nor is the evolution of that life
over billions of years.-a The Biblical order of the creation of life on earth is as wrong as the shape of the earth and it's place in the universe.-a Nothing about nature will support your Biblical beliefs.-a You have to acknowledge that nature is not Biblical, and this fact does not matter for some reason when it is the basis for your denial of reality.
Gap denial is never going to support your religious beliefs when the god that fills the gaps is not Biblical.-a The Supreme court was correct in their comments in scientific creationist gap denial.-a Just because we do not currently understand something about nature, is not any support for
your religious beliefs.-a This is obviously the case with gaps that need
to be filled by gods that are not Biblical.

Thanks for the feedback. He is an interesting "bridge" case, being
connected personally and significantly with Miller and ID.
OoL is of course highly contended (most recently, Tour vs Farina, etc),
but Peltzer's responses I think demonstrate that there are
scientifically credible and substantial arguments against naturalistic abiogenesis.
