I used to hear that a lot- populations evolve (not individuals). Yet natural selection is an IDIVIDUAL thing with populations often coming to the aid of the less fit. The variation is an IDIVIDUAL thing too.
Populations do not reproduce, INDIVIDUALS do. And you can't have evolution without reproduction, so populations don't evolve, the individuals do.
Biological evolution requires reproduction. Populations do not reproduce. Therefor populations cannot evolve, biologically.
EvoTARDs get these catch phrases in their little pointy heads and they think they actually mean something...
