Humans Are Still Evolving

Sir David Attenborough said something stupid the other day [Sir David Attenborough: Humans have stopped evolving]. (Not for the first time.) He said ...

Because if natural selection, as proposed by Darwin, is the main mechanism of evolution – there may be other things, but it does look as though that’s the case – then we’ve stopped natural selection.

We stopped natural selection as soon as we started being able to rear 95–99 per cent of our babies that are born.

We are the only species to have put a halt to natural selection, of its own free will, as it were.

The headline says that humans have stopped evolving. If that's what he really said then it's easy to prove him wrong by showing that there's a lot more to evolution than natural selection [Have Humans Stopped Evolving?].

But what about his specific claim that natural selection doesn't work on humans any more? I covered that in earlier posts but John Hawks has corrected him today [Humans are still evolving, and soon we'll know a lot more about it]. I love it when I agree with John Hawks! (That's me, visiting him in his lab in Madison, Wisconsin.)
