A brief guide to Darwin`s theory of natural selection (evolution)
... Darwin did two things (1) convinced us that evolution actually occurs (2) provided an mechanism by how it occurs. Latter the more controversial. Darwins theory proceeds from three easy observations. - All species have variations within them. Individuals are not identical. - Some of the variation is ...
