f17 Divergent evolution and speciation
... In time, a species can become more diverse (divergent evolution). Individuals do not carry all the genes of their species. Isolation of interbreeding individuals of a species can give rise to new species. This occurs because linking parts of a subdividing gene pool can by chance become eliminated. F ...
