If you are interested in cannibalism, or biology in general, you should listen to this Cannibalism Talk by evolutionary psychologist Diana Fleischman. I didn’t realize just how many sub-types of cannibalism there were before I listened to this. She doesn’t just cover human cannibalism, she also discusses cannibalism in many other species, and explains why this behavior evolved. Some species will even eat their own offspring! After all, as she often says, the flesh of your own species is the best possible multi-vitamin.
Some of what she says made me feel nauseous, while other parts were funny. For those of you who don’t already know, Fleishman isn’t just a scientist, she’s a vegan. I think this gives her some deep insights into cannibalism that non-vegan biologists may have trouble understanding. I highly recommend listening to this talk and reading some of the well-researched articles on her Sentientist blog. All of them are gems. Her blog is one of the best science-based vegan blogs out there.
