Scientists Find A DNA Change That Accounts For White Skin

Submitted by on December 17, 2005 – 8:55 am No Comment

Washington Post Staff Writer

Scientists said yesterday that they have discovered a tiny genetic mutation that largely explains the first appearance of white skin in humans tens of thousands of years ago, a finding that helps solve one of biology’s most enduring mysteries and illuminates one of humanity’s greatest sources of strife.

The work suggests that the skin-whitening mutation occurred by chance in a single individual after the first human exodus from Africa, when all people were brown-skinned. That person’s offspring apparently thrived as humans moved northward into what is now Europe, helping to give rise to the lightest of the world’s races.

Leaders of the study, at Penn State University, warned against interpreting the finding as a discovery of “the race gene.” Race is a vaguely defined biological, social and political concept, they noted, and skin color is only part of what race is — and is not.

In fact, several scientists said, the new work shows just how small a biological difference is reflected by skin color. The newly found mutation involves a change of just one letter of DNA code out of the 3.1 billion letters in the human genome — the complete instructions for making a human being.
