Human Genome Survey Finds Proof of Recent Evolution
Scott Norris - for National Geographic News - March 8, 2006
"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. ...
The findings, along with other recent studies, begin to provide a kind of genetic narrative of recent human evolution. ...
Genes related to physical characteristics also showed strong evidence of selection, with interesting differences among the three populations. ...
Evidence of different selective pressures operating on different populations may be medically important, says study lead author Benjamin Voight. ...
"This research may provide the foundation for understanding how human evolutionary history has contributed to the susceptibility to complex diseases," the University of Washington's Akey said."
