    What other options are there? Autocatalytic sets can't provide symbolic
    or digital inheritance, which you need make real progress. Peptide
    polymers? Again, can't do templated duplication. It seems that RNA/DNA
    has to be central and early.

    Your digital inheritance did not have to evolve until the genetic code
    could evolve. Simple self replication likely drove the evolution of
    life on earth. You also need the self replication to not be 100%
    accurate, so it has to entail more than just single autocatalytic
    reactions (you can't just keep making the same simple molecule over and
    over).

    Recently a simple self replication reacton of a lipid was put up on TO.
    Lipid bodies formed and multiplied as long as the researchers kept
    adding the starting components. What would likely happen in nature is
    that there would be a mix of starting components, and that self
    replicating lipid bodies would be produced, but other reactions would
    likely also be occuring in the mix. Other types of lipid bodies would
    be produced and even new molecules that were not components of the lipid bodies (non lipid products). This is the type of mess that life as we
    know it would have likely sprung from. Not your made up required
    digital information.





    The environment must also provide sufficient temperature stability,
    pH, mechanical agitation, structure (e.g. niche separation), wet/dry
    cycling, feedstock recycling, waste removal, etc.

    LINEAGE

    OoL assumes countless locations working in parallel as described,
    possibly with localised cross-pollination. However, there must be an
    unbroken lineage (or lineages) to from start to finish. Which implies
    the persistence and stability of the environmental requirements
    described.

    There would be no such thing as an unbroken lineage during the origin
    of life on earth.-a There is nothing keeping any lineage from joining
    with another, splitting and or joining with others.-a There would be no
    genetic code, no genome early life was likely a mess of self
    replicating molecules.-a Once a shell or membrane formed multiple
    replicators could join together as proto cells.-a They could start
    assisting each other in replication.-a There would be no cell lineages
    until you evolve a genome for the RNA world where you need to maintain
    the complementary sequence for the functional RNAs, and even after
    that there is no reason that RNA based cells could not fuse and split
    off new lineages.-a Horizontal transfer of genetic material occurs today.


    What I mean by "unbroken lineage" is this. The pathway from simple
    chemicals to LUCA had to be a continuous process, with successive generations of populations of molecules and then presumably protocells.
    As I indicated, this may well include cross-pollination between other
    local colonies of molecules/protocells. But operative word here is
    "local". These incubators must have been delicately balanced systems,
    with very limited mobility.

    My take is that by the time protocells were being routinely created by combinations of self replicating units that the self replicating units
    would have been spread over a large portion of the earth. Just think
    about how life exists around deep sea vents that are constantly emerging
    and shutting down across the sea floor. Life seems to have originated
    on this earth so close to existence of liquid water that such
    environments would have likely been a major component of the surface of
    the earth at that time. There would have been "cross-pollenation"
    across the planet. This is not linear in your sense. There was no
    genetic code that would determine cell lineages, just bags of self
    replicating molecules with various other functions besides self replication.


    For example, let's say you have a local hot spring system that has given rise to protocell population that has reached RNA replication. How might this genetic information be transferred non-locally? Perhaps a flood
    washes these far away? The transported remnant needs to arrive in a new location that immediately provides a similar environment with ready
    supply of feedstock etc. Without constant replication replenishment your
    RNA quickly degrades. The problem is, a flood event is almost certainly going to do the opposite: disperse the population and deposit what
    remains in hostile locations.

    The whole world was a local hot spring over 4.2 billion years ago.


    What I'm doing here is identifying a point at which prebiotic chemistry necessarily "crosses the Rubicon". After that point, it *must* then constantly replicate to survive. Whether it's RNA or some other polymer
    or other complex molecules doesn't matter. Stasis is no longer an
    option. Growth and selection are the only mechanism available which can prevent the decomposition of what has been developed to this point.

    Do you see how this must be?

    It is what would drive the self replicators to evolve better means of
    self replication. Selection would have been selecting for the self replicators that also did things to facilitate their self replication or
    they would be out competed for resources. The self replicators that
    would survive and continue to replicate would be the ones that could
    combine their talents (other functions besides self replicating) to
    secure the resources that they needed to continue to self replicate.
    You are just describing what selective force was in play to produce
    groups of self replicating molecules to evolve the RNA world and RNA
    based self replicators that needed complementary sequences in order to replicate. RNA likely took over all the cellular functions that the mix
    of self replicators were performing for the protocells because it likely
    could more accurately reproduce those functions using a DNA genome. The genetic code would have evolved because peptides did a better job of reproducing the needed cellular functions, and were likely more
    adaptable in terms of producing new functions that would aid cellular reproduction and the function of the existing RNAs.

    TIME

    How long would this lineage need? One million years? One thousand
    years? 100 million years?

    It isn't just one lineage.-a The number of lineages at any one time
    would be dependent on what environment the self replicators needed to
    replicate.

    So the number of lineages vying to develop the RNA world and future
    genetic code would be dependent on what environment that those self
    replicators existed in.

    There could have been trillions of them around a relatively stable hot
    spring at any one time.


    PROBLEM

    What geological situation on the early Earth could provide the
    continuous, stable environment required for the duration needed? Even
    as little as one thousand years is long for a suitable system of
    geothermal ponds that is *uninterrupted* by any sterilisation/reset
    events.

    Polymers such as RNA break down over hours to decades depending on
    environment. Freezing or drying may extend lifetimes but also pause
    evolution. In any case, when active, continuous replication is
    required for renewal before decomposition.

    1,000 years from chemicals to cells seems impossibly short. And
    100,000 years for the nursery required seems impossibly long.

    Beats me how long it took to evolve the RNA world and subsequent
    genetic code, but life seems to have evolved into the LUCA of Archaea
    and eubacteria soon after the earth cooled enough to have liquid
    water. Just a few hundred million years when the earth's surface was
    likely more uniform in terms of the environment that the first life
    could evolve in.-a The data is also evidence that life evolved
    somewhere else and Archaea and eubacterial lineages were deposited
    onto the earth. Only a single lineage of each survive among extant
    lifeforms and these single lineages both existed to start diverging
    new lineages 3.2 billion years ago.-a Their common ancestor existed
    over 4.2 billion years ago, so the genetic code would have had to
    evolve by that time, and it is possible that it evolved somewhere else.

    What I mean by "unbroken lineage" is this. The pathway from simple
    chemicals to LUCA had to be a continuous process, with successive
    generations of populations of molecules and then presumably
    protocells. As I indicated, this may well include cross-pollination

    My take is that by the time protocells were being routinely created by
    combinations of self replicating units that the self replicating units
    would have been spread over a large portion of the earth.-a Just think

    There was no genetic code that would determine cell lineages, just
    bags of self replicating molecules with various other functions

    What possible "bags of self replicating molecules"?

    How does this "self-replication" occur?

    You're indulging in pure hand-waving, and blithely understating the requirements of self-replication with inheritance of sufficient
    information content and fidelity to support chemical evolution.

    I do not follow the origin of life research because it holds little
    scientific interest for me. It is one of the weakest of scientific
    endeavors. This does not mean that your gap denial is supported in
    anyway. The existing gap destroys your Biblical inferences. It cannot
    be filled by the designer described in the Bible unless you claim that
    none of the incorrect Biblical descriptions count in any evaluation of creation in terms of your Biblical beliefs. You can't do that, and just
    run from that reality. Instead you wallow in the denial in order to
    maintain your Biblical beliefs that you can't support by that denial.

    From what has been put up on the topic on TO some people think that the initial self replicators were not really self replicators, but needed
    mineral substrates on which to create larger organic molecules. No one
    knows what the first self replicating molecules were made of. This
    mineral based replication would need to be replaced by self replication
    of the organic molecule or conglomeration of organic molecules
    (molecules would need to evolve the ability to make the same chemical
    bonds facilitated by the mineral substrate. If amino acids were used to
    make peptides, some of the peptides would need to have peptidase
    activity and start making peptides from amino acids. Some of the
    peptides might start making lipids and in some confined space you would
    get lipid conglomerates formed and even membrane bubbles. If the self replicators had some hydrophobic parts they would associate with the
    lipid ball or membrane. Once there were hydrophilic self replicators
    they would need to be contained within a membrane bubble in order to
    continue to work together to facilitate each other's replication. I've
    seen the claim that the self replicators may have been confined in
    groups in a fine matrix like clay instead of a membrane bubble. It
    doesn't matter because lipid membrane bubbles eventually evolved.

    A recent paper that I saw on the subject had lipids with enzymatic
    activity that would produce more of the same lipid when the reactants
    were present so that as long as you added the starting components the
    lipid balls would replicate and split from time to time and the solution
    would become full of the lipid balls. Lipids have been known to have enzymatic activity for a long time, and I have always wondered why the
    origin of life guys have not concentrated on this simple fact. It means
    that once you have a self replicating lipid conglomerate it can evolve
    other enzymatic activities because with a mix of available components
    you expect mistakes to be made and the structure would not perfectly replicate. My take is that lipids could have been the first self
    replicators and these lipid conglomerates would group together in
    aqueous solution. Since the replication is not perfect you would evolve different enzymatic activities that could facilitate the replication of
    the lipid self replicators, and once membrane bubbles formed their
    products could be held within the bag.

    Hand waving is all that is needed to thwart your denial. Your denial
    doesn't even support your religious beliefs.

    PROCESS

    OoL assumes a progression from simple inorganic chemicals to a
    population of protocells and then on to the first population of
    free- living cells (pre-LUCA).

    Protocells provide encapsulation, replication and heritable
    variation, but are not "alive" in that they require feedstock
    supplies from the environment. The feedstock dependence tapers
    from protocells to pre-LUCA.

    ENVIRONMENT

    This process of chemical evolution and then Darwinian evolution
    requires the environment to supply nucleotides, lipids, sugars,
    amino acids, polyphosphates, metal ions, etc, in certain
    concentrations, with substantial homochirality, etc.

    Who makes this claim?-a We do not know what the first self

    They are a highly useful energy coin for the cell.-a They store
    chemical energy and transfer the chemical energy.-a Polymers of
    nucleotides likely evolved to store nucleotides inside the cells
    and keep them from diffusing out of the cells.

    Lipids may have been among the first simple self replicators.
    Conglomerations of lipids can have enzymatic activity that makes
    more lipid, so the enzymatic lipid structures would get bigger and
    be able to split.-a Lipids could evolve other enzymatic functions as >>>>> they self replicated, different lipids could be made etc.

    Chirality would be set by the self replicators.-a The enzymatic
    functions of the self replicators would likely work for one chiral
    form or the other.-a Just like many enzymes do today.

    Note that I'm not assuming or preferring any particular model here.
    But the paper "The RNA world hypothesis: the worst theory of the
    early evolution of life (except for all the others)" remains the
    frontrunner as far as I'm aware, though now extended to "RNA +
    messy" world. https://pmc.ncbi.nlm.nih.gov/articles/PMC3495036/

    My guess is that no one seriously thinks that RNA came first except
    those that might consider some type of really improbable start to
    life as some type of wildly lucky initial conditions that had
    nucleotides present in the environment.-a My take is that it is much
    more likely that nucleotides were developed as aids to the primitive
    metabolism of the early self replicators.


    What other options are there? Autocatalytic sets can't provide
    symbolic or digital inheritance, which you need make real progress.
    Peptide polymers? Again, can't do templated duplication. It seems
    that RNA/DNA has to be central and early.

    Your digital inheritance did not have to evolve until the genetic
    code could evolve.-a Simple self replication likely drove the
    evolution of life on earth.-a You also need the self replication to
    not be 100% accurate, so it has to entail more than just single
    autocatalytic reactions (you can't just keep making the same simple
    molecule over and over).

    Recently a simple self replication reacton of a lipid was put up on
    TO. Lipid bodies formed and multiplied as long as the researchers
    kept adding the starting components.-a What would likely happen in
    nature is that there would be a mix of starting components, and that
    self replicating lipid bodies would be produced, but other reactions
    would likely also be occuring in the mix.-a Other types of lipid
    bodies would be produced and even new molecules that were not
    components of the lipid bodies (non lipid products).-a This is the
    type of mess that life as we know it would have likely sprung from.

    frontrunner as far as I'm aware, though now extended to "RNA +
    messy" world. https://pmc.ncbi.nlm.nih.gov/articles/PMC3495036/

    My guess is that no one seriously thinks that RNA came first except
    those that might consider some type of really improbable start to
    life as some type of wildly lucky initial conditions that had
    nucleotides present in the environment.-a My take is that it is much
    more likely that nucleotides were developed as aids to the primitive
    metabolism of the early self replicators.


    What other options are there? Autocatalytic sets can't provide
    symbolic or digital inheritance, which you need make real progress. >>>>> Peptide polymers? Again, can't do templated duplication. It seems
    that RNA/DNA has to be central and early.

    Your digital inheritance did not have to evolve until the genetic
    code could evolve.-a Simple self replication likely drove the
    evolution of life on earth.-a You also need the self replication to
    not be 100% accurate, so it has to entail more than just single
    autocatalytic reactions (you can't just keep making the same simple
    molecule over and over).

    Recently a simple self replication reacton of a lipid was put up on
    TO. Lipid bodies formed and multiplied as long as the researchers
    kept adding the starting components.-a What would likely happen in
    nature is that there would be a mix of starting components, and that
    self replicating lipid bodies would be produced, but other reactions
    would likely also be occuring in the mix.-a Other types of lipid
    bodies would be produced and even new molecules that were not
    components of the lipid bodies (non lipid products).-a This is the
    type of mess that life as we know it would have likely sprung from.
    Not your made up required digital information.





    The environment must also provide sufficient temperature
    stability, pH, mechanical agitation, structure (e.g. niche
    separation), wet/ dry cycling, feedstock recycling, waste
    removal, etc.

    There would be no such thing as an unbroken lineage during the
    origin of life on earth.-a There is nothing keeping any lineage

    What I mean by "unbroken lineage" is this. The pathway from simple
    chemicals to LUCA had to be a continuous process, with successive
    generations of populations of molecules and then presumably
    protocells. As I indicated, this may well include cross-pollination >>>>> between other local colonies of molecules/protocells. But operative >>>>> word here is "local". These incubators must have been delicately
    balanced systems, with very limited mobility.

    My take is that by the time protocells were being routinely created
    by combinations of self replicating units that the self replicating
    units would have been spread over a large portion of the earth.
    Just think about how life exists around deep sea vents that are
    constantly emerging and shutting down across the sea floor.-a Life
    seems to have originated on this earth so close to existence of
    liquid water that such environments would have likely been a major
    component of the surface of the earth at that time.-a There would
    have been "cross- pollenation" across the planet.-a This is not
    linear in your sense. There was no genetic code that would determine
    cell lineages, just bags of self replicating molecules with various
    other functions besides self replication.

    What possible "bags of self replicating molecules"?

    How does this "self-replication" occur?

    You're indulging in pure hand-waving, and blithely understating the
    requirements of self-replication with inheritance of sufficient
    information content and fidelity to support chemical evolution.

    Otherwise it's just random garbage turning into difference random
    garbage.

    What does this matter when you can't deal with what else is wrong with
    your denial?

    I do not follow the origin of life research because it holds little
    scientific interest for me.-a It is one of the weakest of scientific
    endeavors.-a This does not mean that your gap denial is supported in
    anyway.-a The existing gap destroys your Biblical inferences.-a It
    cannot be filled by the designer described in the Bible unless you
    claim that none of the incorrect Biblical descriptions count in any
    evaluation of creation in terms of your Biblical beliefs.-a You can't
    do that, and just run from that reality.-a Instead you wallow in the
    denial in order to maintain your Biblical beliefs that you can't
    support by that denial.

    -aFrom what has been put up on the topic on TO some people think that
    the initial self replicators were not really self replicators, but
    needed mineral substrates on which to create larger organic
    molecules.-a No one knows what the first self replicating molecules
    were made of.-a This mineral based replication would need to be
    replaced by self replication of the organic molecule or conglomeration
    of organic molecules (molecules would need to evolve the ability to
    make the same chemical bonds facilitated by the mineral substrate.-a If
    amino acids were used to make peptides, some of the peptides would
    need to have peptidase activity and start making peptides from amino
    acids.-a Some of the peptides might start making lipids and in some
    confined space you would get lipid conglomerates formed and even
    membrane bubbles.-a If the self replicators had some hydrophobic parts
    they would associate with the lipid ball or membrane.-a Once there were
    hydrophilic self replicators they would need to be contained within a
    membrane bubble in order to continue to work together to facilitate
    each other's replication.-a I've seen the claim that the self
    replicators may have been confined in groups in a fine matrix like
    clay instead of a membrane bubble.-a It doesn't matter because lipid
    membrane bubbles eventually evolved.

    A recent paper that I saw on the subject had lipids with enzymatic
    activity that would produce more of the same lipid when the reactants
    were present so that as long as you added the starting components the
    lipid balls would replicate and split from time to time and the
    solution would become full of the lipid balls.-a Lipids have been known
    to have enzymatic activity for a long time, and I have always wondered
    why the origin of life guys have not concentrated on this simple
    fact.-a It means that once you have a self replicating lipid
    conglomerate it can evolve other enzymatic activities because with a
    mix of available components you expect mistakes to be made and the
    structure would not perfectly replicate.-a My take is that lipids could
    have been the first self replicators and these lipid conglomerates
    would group together in aqueous solution.-a Since the replication is
    not perfect you would evolve different enzymatic activities that could
    facilitate the replication of the lipid self replicators, and once
    membrane bubbles formed their products could be held within the bag.

    Once upon a time in Lipid World there was sad bag of chemicals... Now
    you're just blowing bubbles.

    What are you blowing? It looks like all it has been is smoke. That is
    all that is needed against your denial. You don't even want to fill the
    gap with some designer. It would just be more about nature to deny.


    Okay, that's a bit unfair, and I do appreciate your willingness to
    seriously tackle topics. Whatever model you care to name, sooner or
    later you're going to need templated, genetic polymers doing heavy
    lifting. The only realistic candidate for this is RNA or DNA, and these require a constant supply of nucleotides that are sufficiently pure, concentrated, homochiral, and activated. For thousands or millions of
    years. Just let that sink in.

    The genetic code likely evolved after the RNA world evolved. Polymers
    of RNA were being made by replication of RNA off RNA templates, and then
    DNA templates.

    My take is that amino acids started to be polymerized into polypeptides
    in order to store amino acids that were used to make nucleotides.
    Things like tRNAs may have evolved to keep the amino acids that were
    used in synthesizing nucleotides from difusing out of the cell membrane.
    RNA ribosomes likely evolved peptidase activity in order to use tRNAs
    to polymerize the amino acids into peptides to store the needed amino
    acids. The genetic code may have started to evolve in order to
    polymerize only the amino acids needed for RNA and cell metabolism. It
    would have allowed the storage of only the required amino acids. The
    code likely evolved to it's current form when peptides started to do
    useful things for the cell, and specific mRNAs started to be selected
    for along with tRNAs for more amino acids that were useful in creating functional proteins.

    That should be more than enough to blow away your smoke.


    Whatever model you care to name -- RNA world, metabolism-first, lipid-
    world hybrids, messy world, autocatalytic networks -- none of these
    permit you to wave away this requirement.d

    You seem to be wrong again.



    Hand waving is all that is needed to thwart your denial.-a Your denial
    doesn't even support your religious beliefs.

    Hand waving is what you are stuck with. Just try to support any of your Biblical beliefs with more than hand waving. We know that RNA ribosomes
    can exist. We know that tRNAs can exist. We know that mRNAs can exist.
    We have created RNA polymers that can charge tRNAs with specific amino acids. RNA polymers can have many other enzymatic activities. Specific
    RNA polymers can be replicated. The RNA world isn't just speculation it
    has pretty much been proven that it could have existed. Name something
    about your religious beliefs about the designer-did-it that has more
    going for it?
