I have a genuine question: In a world fully connected where cultural and national boundaries sexist but travel is for the most part free, and immigration between countries is exclusive and total, meaning if you go to X country you adopt X culture, wouldn't humanity tend to become a single race of mutts?
From the perspective of genetic fitness, wouldn't a mutt be the most adaptable to the greatest number of situations as compared to one specific subspecies?

I love this video I watched years ago. It fits perfectly to this discussion, worth watching.
