Meat eating made us human. The anthropological evidence strongly supports the idea that the addition of increasingly larger amounts of meat in the diet of our predecessors was essential in the evolution of the large human brain. Our large brains came at the metabolic expense of our guts, which shrank as our brains grew.
For years anthropologists have speculated about why humans developed such large brains so quickly – from softball size to what we have now in just a short 2 million years. Below is a graphic showing hominid/human brain growth over time.
I hope you are now armed with enough knowledge to be able to see through these articles and/or charts that are all too common showing how the GI tract of humans is closer to that of a gorilla than it is to that of a cat or some other carnivore. It seems to me that Aiello and Wheeler have pretty thoroughly demolished the notion that humans are actually designed by the forces of natural selection to be vegetarians. Based on the data and the argument they present, it is actually the opposite: we evolved to be meat eaters.
It was our gradual drift toward the much higher quality diet provided by food from animal sources that allowed us to develop the large brains we have. It was hunting and meat eating that reduced our GI tracts and freed up our brains to grow. As I wrote at the start of this post, the evidence indicates that we didn’t evolve to eat meat – we evolved because we ate meat.

IF HUMANS ATE THAT INSTEAD OF MEAT WE WOULD HAVE NEVER FOUND OUT HOW TO USE OUR THUMBS
