Then the surviving population would be resistant. That's how evolution works.

If Bill Gates killed every person in New York that didn't have a bike, would it be accurate to say that he gave every New Yorker a bike?

[staticautomatic → whatshisface]

No, but it would be accurate to say that he was exerting selective pressure on people to have bikes.

[nwienert → whatshisface]

Yea, if Bill Gates was evolution.

More seriously: the analogy is broken. Here’s it fixed: If Bill killed everyone without a bike and then the bikers naturally gave birth to kids who came with bikes from then on.

The title implies cannibalism could give general disease resistance to an individual, but the article is about a population developing resistance to a cannibalism-induced disease due to individuals without the resistance dying off. That's the disconnect the parent comment was referring to.
