I'm guessing that's far more environmental than genetic. (It would be very impressive genetic drift!)
Lots of people are talking about natural selection, which may very well not be happening so much anymore. But sexual selection and DNA insertions done by viruses and bacteria ( http://news.nationalgeographic.com/news/2007/03/070305-evolution-germs.html ) are still happening. I think we're going to see the human race shaped far more by sexual than natural selection in the next few generations, as with Make it Lady's example of the bucked teeth.
