Survey of Human Genome shows proof of Evolution

(National Geographic) Signs of recent evolution by natural selection are widespread across the human genome, experts say.

Genome researchers at the University of Chicago have identified more than 700 regions in human DNA where apparently strong selection has occurred, driving the spread of genes linked to a broad range of characteristics.

"These are very recent eventsówithin the past ten thousand years," said Jonathan Pritchard, a geneticist whose laboratory team conducted the study.

The results suggest that humans in different regions have continued to adapt in numerous ways to both environmental changes and cultural innovations.

Many of the genetic changes Pritchard's group detected came during or after the emergence of agriculture, beginning about 10,000 years ago, and long after the formation of modern human populations.
