This worldwide interbreeding likely slows everything down- or may create a brand new effect never before seen in biological evolution.
Just an observation here:
In HG Wells' novel "The Time Machine" he posited that at some distant future time the human race would evolve into two separate groups which could rightly be considered separate species.
Only point being that perhaps we shouldn't presume that our long-term future involves a world in which interbreeding of humans remains a possibility?
Indeed, if we start to think about the possibility of space-travel, and the colonization of distant planets, a more likely scenario arises; it might be that we end up with significant human populations isolated from one another due to the immense distances of space and the resultant difficulties which would arise in maintaining a physical interconnection. There's LOTS of intriguing possibilities one might play with here!
