If Man had not branched out genetically at some point, we would all look the same, and there would be no green eyes vs blue eyes or blond vs red hair, let alone all the other various differences between people even within sub-sub-groups. However, in the modern era, it seems apparent that this branching-out has mostly ceased. Now, there's still some divergence occurring in some species, e.g. the emergence of floppy ears in the Russian fox breeding experiments. But in breeding for certain traits, other traits are necessarily bred out. This is a loss of genetic info—a one-way street. The ur-wolves could split into today's dog breeds, but each successive generation has less divergent potential because their genetic info has been collapsed into branches, losing the alternatives in the process. Additionally, even without explicitly selective forces, random mutations are gradually erasing meaningful info and replacing it with meaningless noise anyway. This follows the universal law of entropy, unlike the absurd teaching of Darwinism (which posits that new info emerges from noise). This may be one of the reasons why God promised not to flood the earth with water again; a natural division into the great races from 3 men and their wives could not happen today. (Aside: I suspect the genetic connection of "domestic" features like floppy ears to domestic behavior is by Design.)
