Some scientists believe that what made Homo erectus the species that eventually evolved into us is that they began to cook their food. The article says,
This seminal event had huge implications for hominid evolution, giving the ancestors of modern humans time and energy for activities such as running, thinking deep thoughts and inventing things like the wheel and beer-can chicken.

One of the comments makes a point, which I think is a great one. That perhaps the most important thing that cooking did was help to kill bacteria and parasites that in turn, helped to lengthen the lives of our great-great-...great-great grandparents.
Just one more reason to keep on cooking--to keep us from extinction!
