Giving such prominence in human evolution to a male-dominated activity, however, was reviled for years as both sexist and ignorant of the facts. Gombe chimps face the same dearth today.

Which explains the curious fact that after a kill the chimps don't feast on the tenderest, most nutritious flesh.
Meat contains no magic ingredient for cognitive development.
