... Evolution to a geneticist: a change in gene frequencies. Natural selection: a consistent bias favouring some genotypes over others. Evolution can occur in the absence of natural selection, via genetic drift or neutral evolution. Natural selection can stabilize the status quo; zero evolution. ...
