Dunno. †But Dave Wisker is Louis:

Thatís not quite true. In the case I quoted above, the three species of birds do hybridize (albeit rarely) when they come into contact, though probably less often than Africans and Irish do when they come into contact. This is to be expected when closely related populations begin to diverge: somebody living in New England and travelling to Africa would have no problem producing fertile offspring with Africans. However, should that same person attempt to produce fertile offspring with artichokes or sheep anywhere, the results would be as expected considering the time since the divergence of those lineages.
So, getting all hot and bothered about species and varieties in early stages of divergence is a waste of time and a diversion from the issues being discussed.
Ha! I don't live in New England. But Cakeboy does.
