Hundreds of Human Genes Still Evolving

Those that know me, know I'm really interested in science. I mean, I have a B.S. in Computer Science, so already you know I lean that way.

Daily, I read articles about advancement, discoveries, research, ideas, etc. and today I found something interesting. This article here talks briefly about many genes in humans still evolving. I already wondered if the colors of our skin of different groups in the world was due to evolution. According to this article it is. It basically explains why I'm a white dude who likes milk and can drink a lot of beer.
