Sorry Adrian, but this species concept has been wiped out by ... nature.
There have been crosses which should not have occured. So all red canary
birds result from a cross between a Middle American finch and the canary
bird. These were definitely not one species. Ernst Mayr made a new species
concept which is widely accepted. I hope I'll get it from my brains now:

A species is a member of a geographically isolated, self reproducing
community.

I think it is really interesting when you start putting everything together
it sort of makes it all believable.

What happened to the old theory of if 2 species could breed together and
produce fertile offspring they were the same species?
