Who cares, chimpout.com is better anyways.
Fallow, You seem to be using race and subspecies to mean two different things, while I'm taxonomy they are considered the same exact thing (or so the Internet and my one professor... okay well she was a a little unreliable... so yeah the Internet tells me)
As for those extreme valleys, those polymorphs, while having a cluster of genes as you described, could still genetically be considered the same species with a differing color pattern, if mating selection were to changed based on the color, in the sense that only the ones that have almost the exact color patterns mate, then I would say that they would be a subspecies because they could mate with each other but are isolated by sexual selection. I guess I would like to correct what I meant... it's not just a geographical isolation, but many others that could also account for not being able to reproduce with others of said species...
And for the last one, while it is true that it may be a mechanism for divergent evolution, separation doesn't always mean that they will evolve into another species; the peregrine falcon is spread throughout the world and it has yet to evolve into a new species.
