I just finishedOn the Origin of Species. It seems Darwin is saying that characteristics that make it less likely for an organism to survive will drop out over time. But other scientists tell me that cancer has a genetic link, that suicide has a genetic predisposition, etc. Many diseases have been shown to have a genetic basis. So where does that leave Darwin's theory of natural selection? Shouldn't these genetic predispositions have dropped out a long time ago?
