NOVA Short | Evolution in Action

NOVA visits David Wake, a renowned evolutionary biologist at the University of California, Berkeley, as he explains why members of the same species of California salamander look and behave so differently. It's a case study of Darwin's theory of evolution by natural selection, and an example, Wake says, that Darwin himself would have loved. Watch NOVA every Wednesday night on PBS.
