I found this rather interesting: http://www.chicagotribune.com/news/nationworld/chi-0603070187mar07,1,6967465.story?coll=chi-newsnationworld-hed&ctrack=1&cset=true
So we are still evolving after all.

EDIT: If for some reason you can't read the first link (works fine for me, but whatever), here's the text:
And okay, I'll edit the signature.

Genes show humans are still evolving

Published March 7, 2006
Providing the strongest evidence yet that human beings are still evolving, researchers have detected some 700 regions of the human genome where genes appear to have been reshaped by natural selection, a principal force of evolution, within the last 5,000 to 15,000 years.
The genes that show this evolutionary change include some responsible for the senses of taste and smell, digestion, bone structure, skin color and brain function.
Under natural selection, beneficial genes become more common in a population as their owners have more progeny.
Three populations were studied: Africans, East Asians and Europeans. The selected genes affect skin color, hair texture and bone structure.
The study of selected genes may help physical anthropologists explain why people over the world have a such a variety of distinctive appearances, said Spencer Wells, director of the Genographic project of the National Geographic Society.
"There is ample evidence that selection has been a major driving point in our evolution during the last 10,000 years, and there is no reason to suppose that it has stopped," said Jonathan Pritchard, a population geneticist at the University of Chicago who headed the study.
The findings are in Tuesday's issue of PLoS-Biology, published by the Public Library of Science, a non-profit organization.
