“The most powerful ways in which meat has us hooked are not biological but social. The tradition of sharing meat goes back an estimated 2.5 million years, to the time before Homo sapiens, when researchers think our distant ancestors started bringing home flesh and dividing it among members of the group. Hunting animals with the tools available at that time was inefficient; it would have been much easier to get the calories by foraging.
So paleoanthropologists think that the point of hunting wasn’t simply to scare up food but to form alliances, win favors, and strengthen bonds among members of the clan.”
