(90,061 posts)Cooking goes back a long ways. They are thinking now it much predates Homo Sap., possibly necessary for our evolution to modern form. And probably it was important for meat from the beginning. But I'm talking about fat, livers are full of fat, among other things. Cooking may have been necessary for the evolution of our large brains, which are biologically and nutritionally very expensive to operate.
Meat's a lot easier to get down if you let it "age" a bit, and if you are hungry enough that will start to look good to you. Insects are a great mix of fats and protein too, and I expect we once relied on them a lot at times.
Humanoids have been able to make stone tools for millions of years, and one of their primary uses was the disassembly of carcasses into convenient size pieces for consumption, which is why we no longer need those big canines (but we still have the big roots for those teeth, put your finger up there and see, we haven't lost those yet.)
