Speciation can be facilitated by the separation and eventual isolation of two or more fractions of a population. It seems that physical isolation is necessary before a group can begin to split into new species. If this is so how did the millions of isolation events occur that would be needed to create the millions of species that exist and have existed? I assume it has to do in part with different organisms filling different niches. Could you fill me in on the theories that deal with this specific area? Thanks.
