Problem:
My understanding of evolution is that genetic mutation occurs in individual members of a species, and they become a new species.
Required:
Question: Isn't a definition of species a group of genetically similar organisms that are pretty much exclusive in breeding ability?
Question: Wouldn't there have to be a male and female with the same genetic divergence at the same time to make a new species?
Question: What is the popularly accepted mechanism for the splitting into a new species in organisms that require sexual reproduction?
