A quick question for the biological gurus at this board:
Assuming that an arbitrarily-sized group of humans was isolated from the rest of the population, would a new species be formed? If so, how long would this take? I remember seeing a television program a few years ago, that featured a similar situation, where a number of biologically isolated environments existed (in South America, I think).

Human speciation
Thanks Nosy!
Just to make it a bit clearer...If a certain number of people- say 100,000- were to be isolated in a remote part of the planet...how long would it take for this isolated group to become unable to interbreed with Homo sapiens?
Is it even possible?
