I took a few Bio and Anthro classes in college.
There hasn’t been concrete evidence on WHY cave mans cook food, or why the first humans decided to cook food.
It was theorized that it is all coincidental. As in, a random fire just happened to heat up a piece of meat and some caveman really wanted to eat it regardless.
But we do believe humans, or cave mans have evolved to be thinkers and our brains has evolved to be more powerful because of calorie dense food, AKA meat. Our brain uses about 20% of all the calories we intake. We do believe this has to do with fire, and raw food being a combination, and a pure coincidence that we are so intelligent.
