Sunday, December 18, 2005In 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. A different mutation made the lighter skin color for Asians. Kind of makes you wonder what happened those many, many years ago when the first person with the mutation was born? Were they ostracized and forced to migrate further north, intermarrying along the way? Were their off-spring also ostracized and pushed even further North? We'll never know, but it would explain why the Meditarranean people are not as light as Northern Europeans but not as dark as people from Africa. Wouldn't it? (And doesn't the same gradation occur pushing out from Africa and the Middle East to India to Northern Asia?) posted by Sydney on 12/18/2005 05:14:00 PM 1 comments 1 Comments:
Well, I personally think it should be pointed that there is nothing unnatural in being "mutant", since mutations are believed to be one of the mechanisms of evolution. By 5:20 AM , at |
