Food for Thought: Was Cooking a Pivotal Step in Human Evolution? - Scientific American
These converging pieces of evidence point to an earlier date for the adoption of a cooked diet, in line with Wrangham’s proposed time line. But many exciting questions remain open. How much of these changes were due to eating cooked foods specifically, versus the increased use of other processing techniques such as pounding or cutting foods? Did the adoption of cooking—generally a communal process in humans—require changes in our social behavior, given that other apes rarely share food? Are there other ways to grow a big brain? Answering these questions will continue to shed new light on human health, human psychology and the origins of our species.
