Eh, it doesn’t mean that it wasn’t at one point or that it can’t be part of our reproductive strategy in the future. I’d even say that murder and cannibalism are very normal aspects of our species.

E: I guess I’m getting downvoted for seemingly pulling that out of my ass. But I recommend the book Dinner with a Cannibal: The Complete History of Mankind’s Oldest Taboo by Caroline A. Travis-Henikoff. It’s a serious look at how cannibalism shaped our cultures and evolution.
