Scientists may have finally solved the riddle of Tyrannosaurus rexrCOs
small arms, which have always stood out as the oddest feature in the
mightiest of dinosaurs, prompting jokes and a century-plus debate on
their purpose and evolutionary history.

T. rex was one of many meat-eating dinosaurs with puny arms, and over
the years scientists have come up with theories for the forelimbsrCO
function, including holding or pinning down prey and impressing
potential mates during courtship. More recent studies have suggested
that the arms became smaller to reduce the risk of being bitten during
feeding frenzies, while a longstanding theory is that they are simply vestigial rCo they had no practical purpose and therefore shrank. But a consensus is lacking.

Now, a new study published May 20 in the journal Proceedings of the
Royal Society B aims to settle the debate once and for all. Based on an analysis of 85 species of dinosaurs, the study concluded that tiny arms
were an evolutionary trade-off caused by another body part becoming ever larger and taking up resources rCo the skull.

rCLIf yourCOre a dinosaur with a very strongly put together skull, chances
are yourCOre going to have very small forelimbs,rCY said Charlie Roger Scherer, a doctoral student in the department of Earth sciences at
University College London and the studyrCOs lead author. rCLAnd it doesnrCOt really matter how big you are rCo you could be 1 ton in weight, or 10 tons
in weight. If you have a strong skull, yourCOre going to have relatively
small arms.rCY

The reason is that rCLevolution doesnrCOt like to have everything all at once,rCY as Scherer put it, because it tends to prioritize one thing over another. rCLIf you want to focus on using your head to bring down large
prey, you donrCOt really want to be putting much effort in keeping your
arms long and with claws, because yourCOre probably not really going to
need that, so evolution kind of says, rCyWe donrCOt need the arms anymore,
so letrCOs shrink them down and put more energy into keeping the skull
strong and using that as the primary weapon.rCOrCY

They left the earth long time ago.

It's simply not possible that they lived here for 170 million years without evolving, building civilisation, and leaving the earth while erasing the traces.

Do you know how long is 170 million years.

Allegedly we're here only 0.3 million years, they had about 600 times more time.

Nah, the asteroid hit three days before the spaceships were ready to
take off...
