How did cooking food affect human evolution?

Cooking had profound evolutionary effect because it increased food efficiency, which allowed human ancestors to spend less time foraging, chewing, and digesting. H. erectus developed a smaller, more efficient digestive tract, which freed up energy to enable larger brain growth.
