Fwd: Human Evolution Still Happening

[Guest guest]

The following article could explain why not all of us can tolerate a

raw food diet or a " paleo " diet or other variations on what is assumed

to be early human fare.

CHICAGO, -- Even as controversy continues over the theory of

evolution, scientists say they've found the strongest evidence yet

that humans are still evolving. University of Chicago researchers say

they've found approximately 700 regions of the human genome where

genes appear to have been reshaped by natural selection within the

past 5,000 to 15,000 years, The New York Times reported Tuesday.

Scientists told The Times the changes may be the result of people

leaving their hunting and gathering way of life for settlement and

agriculture. The finding also adds substantially to the evidence that

human evolution did not grind to a halt in the distant past, as is

assumed by many social scientists, the newspaper noted. " 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 Pritchard, a population

geneticist at the University of Chicago who headed the study.

Pritchard and his colleagues, Voight, Sridhar Kudaravalli and

Xiaoquan Wen, report their findings in the current issue of PLOS-Biology.
