Still Evolving, Human Genes Tell New Story

Researchers have found 700 regions of the human genome where genes appear to have been shaped by natural selection within the last 15,000 years. Taste, smell, digestion, bone structure, skin color and brain function all appear to have evolved relatively recently.

I'm most interested in what this says about the concept of race. That racial differences have evolved so recently reinforces that those differences are relatively slight and have to do mostly with surface appearance.
