here is my evidence.
Its further emphasized on page 2 of the article

Lucas argues that the mechanical process of chewing, combined with the physical properties of foods in the diet, will drive tooth, jaw, and body size, particularly in human evolution.

This is in reference to herbevores obviously, since carnivores do not chew. Thus the athrophy of jaw size correlates to the need to chew less, the need to eat less plants and more meat. (you have to chew plants, you don't chew raw meat).
furthermore...
| quote: |
Essentially, by cooking our food, thereby making it softer, we no longer need teeth big enough to chow down on really tough particles. By using knives and forks to cut food into smaller pieces, we no longer need a large enough jaw to cram in big hunks of food.

As far as i know, early humans mainly cooked meat on the fire. If you find anything else, please share your references.
More calories less volume = more time to do shit. We aren't brontosaurs' spending 99% of our waking hours grazing just to meet daily dietary requirements.
Think about calorie consumption and the time it would take to meet your daily requirements based on plants available to you in a forest.
Now you can take a small percentage of that volume and get the exact same dietary benefits eating meats.. Hence a period that allowed for free time and mind development.
omega 6 can be found in poultry and 3 in fish.
lets not forget the social development hominids gained through organized hunting.
The end result is as follows.
Humans evolved from earlier primates, hominids
These hominids hunted ate meat and cooked it.
We are a product of those hominids.
Thus we evolved to eat meat.
If we didn't eat meat then ..
GUESS WHAT?!
CONSEQUENCES WOULD NEVER BE... THE SAME!
