I wonder if this change happened when we learned to cook meat over a fire, instead of eating it straight off the carcass.

This might explain democrats.
Lots of talking about nothing = big jaw muscles.
Big jaw muscles = little room for brains.

"I wonder if this change happened when we learned to cook meat over a fire, instead of eating it straight off the carcass." I expect we discovered 'cooking/fire' because of our weak bite, easier to chew.

No way. The reason the brains got bigger is that the cave men had those big clubs and used to smack each other in the head with those clubs (post monolith) which made their brains swell up, forcing the jaw to get smaller. These evolutionist types are always getting it backwards.

It sure seems that "experts" think they "know" a lot more than what used to be called belief.
Not that this isn't true , but perhaps the mutation was due to no longer needing the strength to bite? I don't know and no one else does either.
Richard Feynman, a great scientist, would often say "that is something no one knows". Sadly that line is missing from so many of todays "scientists".

Other primates remained stuck with mighty muscles that squeezed the skull in a vice-like grip.And we'll see plenty of examples during this year's RAT convention...

I can understand how our jaw muscles could weaken over time, but how does a new area (the brain) expand without a need for it to do so. This is not evolution but wishful thinking.
In evolution an ability is created when there is a need, not before. Or is evolution really devolution?

I don't buy it, it is too simple an explanation, the muscles kept the brain from growing?? What? Nonsense.

Makes more sense to me.
But I also suspect the true second edition of "The Joy of Cooking" is done in spit hand-print somewhere in a cave in France :->

Humans owe their big brains and sophisticated culture to a single genetic mutation that weakened our jaw muscles about 2.4 million years ago, a new study suggests. Sorry, but that has the clear ring of BS about it. Jaw muscles significantly stronger than ours would be useful for only one thing, i.e. killing and rending prey animals with our teeth, and there is simply no evidence of any hominid or ape for that matter doing that. We're supposed to be descended from herbivores, remember?
To: EggsAckley
Animals, and animal heads come in many sizes. Some even have massive jaw muscles that run up to the cranial crest, but these can also have large heads. We lack the cranial crest since we appear to have physiques that are arrested in development in some respects at the infant stage, but we could have cranial crests and massive mandibular muscles without reducing the internal volume of the brain cavity. Some genetic manipulation ought to do the trick.
