Apes Like Cooked Food, and What that Means for Human Evolution. Humans are the only species on earth that cooks its food. Not only do we cook our food, but we usually find the flavor of cooked foods preferable to the raw version. . The key to cooking lies in the energy demands of our giant minds.
According to a new study, a surge in human brain size that occurred roughly 1.8 million years ago can be directly linked to the innovation of cooking. Homo erectus, considered the first modern human species, learned to cook and doubled its brain size over the course of 600,000 years.
Did cooking food make us human?
All known human societies eat cooked foods, and biologists generally agree cooking could have had major effects on how the human body evolved. For example, cooked foods tend to be softer than raw ones, so humans can eat them with smaller teeth and weaker jaws.

Why does cooking meat make it safe to eat?
Very simple: it kills bacteria. The recommended cooking temperatures are empirically derived. They lead to a log 7 reduction in the amount of bacteria present. That is when you have a piece of meat, 1 in 10 000 000 of the bacteria on it remain alive after cooking.
When did humans start cooking food?
There is evidence that Homo erectus were cooking their food as early as 500,000 years ago. Evidence for the controlled use of fire by Homo erectus beginning some 400,000 years ago has wide scholarly support.
