In Galapagos Finches, Biologists Catch Evolution in the Act

If geographically isolated finches with accents constitute a new species of finch, are geographically isolated people groups with unique languages all different species of people?

P.S. Doesn't this sound like a set-up for a bad joke:

"These offspring became isolated because they have the avian equivalent of a strange accent... So the immigrant bird's descendants have bred only with each other for three generations."

Good point.

Wars have been fought on this topic.

This article is unbalanced as it fails to mention the alternatives to godless evilution.

Before you scoff, remember much work has been done in recent years and many of the earlier objections have been overcome. In particular FSM creationism has potential to become a rich source of answers to the questions these scientists ask.
