Our ancient human relatives had jaws like nutcrackers that allowed the hominids to chomp down on hard nuts and seeds and adapt to changes in food sources in their environment, a new computer simulation reveals.
Today's humans have comparatively small faces and teeth, making us ill-equipped to bite down forcefully on hard objects. Apparently that wasn't the case for Australopithecus africanus , which lived 3.3 million to 2.5 million years ago.
An international team of researchers used computed tomography scanning to digitally recreate an A. africanus skull to see how the jaw operated and what forces it could produce. Then, they added measurements of how the facial muscles work in chimpanzees , which share common features with Australopithecus .

...”Our ancient human relatives had jaws like nutcrackers that allowed the hominids to chomp down on hard nuts”...
I thought all hominids like to chomp on hard nuts...?
That explains the squarish look to the faces on Egyptian hieroglyphics?
Great minds............ ;-)
Did the computer simulate harder teeth, also?
“Our ancient human relatives had [big thick] jaws”
this is the same tripe that had aboriginies in zoos because of their “thick big jaws”
by this evolutionist thinking, aboriginies are “less evolved”.
which is nonsense. anyone can develop a thick jaw IN THEIR LIFETIME by eating hard foods. a study of the habitually unshod found that their feet bones became EXACTLY the same as “ancient man”.
these studies are meaningless. their outcome is decided before they are even carried out.
curious that modern humans would lose this very necessary-to-survival attribute.
I’ve got 100 horsepower jaws but my teeth are only rated to 50.
For cracking nuts...Instead of hitting them with a rock?? Sure....I believe even gorillas use rocks to crack them.
Is this a real product?
Our current jaws are more than ample for cracking nuts. Its our teeth that aren’t, and theire teeth weren’t much different from ours.

It’s probably due to a common vitamin K2 deficiency.
