Maybe because people tend to reproduce fairly early in life (usually half of lifespan) so living an extra X years doesn't really allow you to have more children

Maybe because people tend to reproduce fairly early in life (usually half of lifespan) so living an extra X years doesn't really allow you to have more children, and therefore the mutation of longer life doesn't get a huge enough advantage in natural selection?
- glenstein 6y agoRight. And I suppose that the other side of the same coin is that we might want to deliberately delay having children as long as possible if we were actually trying to steer evolution toward optimising for longevity.
