Oh, there could very well be a base drive for cannibalism. We can test ancient archaeological sites for cannibalism. When humans eat other humans, it leaves distinct traces in human waste that can be preserved in the fossil record. You can tell what an ancient human ate by analyzing their fossilized poop. And cannibalism was very common in pre-history, in societies all over the world. We're all descended from cannibals.

Worse still, it wasn't usually about food. It was usually done for power, war, dominance, and religious reasons.

Most of cannibalism throughout human history was not due to hunger. The Aztecs didn't build a skull pyramid because they were a bit peckish.
