This is what you call, "fancy testing" using lasers...

Not surprised at all that their study showed that we current humans (Sapiens) were mostly beef eaters before the advent of agriculture.

Another thing is how an organism like a cray fish (or whatever), can have zero change in its genetic structure. It could be that certain ocean critters are in the same static conditions, whereas ancient peoples gradually learn to make things better, learn to use fire, learn agriculture, and so forth. The last one might have been a huge boost.

Australopithecus while mainly plant consuming none the less started to consume small amounts of beef (scavaged carcasses) which ''probably'' gave them the nutrients (fat solubles A,D,E,K) that allowed successive species of the human brain to expand in size over the coming hundreds of thousands of years starting with Homo Habilis some 2.3 million years ago.

I didn't remember seeing the Keyenthropus at all. But I just happened to come across a number of various types of hominids in one spot.

You may find the extinct human species Homo Heidelbergensis interesting as they were supposedly the ''giant'' species of humans as the males averaged well over 6 feet in height upwards to 7 feet tall and their brain size averaged between 1100 cc to 1400 cc (homo sapiens 1400 cc). However that being said it's hard to know much about them as they lived from around 700,000 years ago to around 400,000 years ago located primarily in Europe (before Neanderthals). I'm perplexed about how a physically powerful and intelligent species of humans went extinct after surviving for some estimated 300,000 years?
