According to a recent statistical analysis, all humans probably descend from one person who lived between 2,000-5,000 years ago, and all people who were alive 5,000-7,000 years ago whose lines did not die out are all ancesters to everyone now alive.

My knowledge of statistics is far too limited to even begin to understand the analysis presented in the article, but the discussion is fascinating. It certainly gives the lie to any claim that any "race" is more advanced than any other, at least as far as any scientific discussion is concerned. Evolution doesn't proceed anywhere near the pace that would be required for there to be any but superficial differences between "races."
Adminnemooseus suggested that this topic belongs in Human Origins.
Edited by Adminnemooseus, : Added the "(re: Recent common ancestors to all living humans)" part to the topic title. I must file the original title under "cute but pretty worthless". It is my unrealized hopes that such topic titles get fixed before the topic is promoted out of the "Proposed New Topics" forum. I also don't understand why this topic wasn't promoted to the "Human Origins" forum.

Re: Seems Bogus
Apparently you didn't read the whole article.
The model also had to allow for migration based on what historians, anthropologists and archaeologists know about how frequently past populations moved both within and between continents. Rohde, Chang and Olson chose a range of migration rates, from a low level where almost nobody left their native home to a much higher one where up to 20 percent of the population reproduced in a town other than the one where they were born, and one person in 400 moved to a foreign country.
Now, if you wish to question the methodolgy, the statistics or the range of migration rates used, that's fine. But to simply state they didn't account for regional separation when the article clearly says that they did seems disingenuous to me.
