Genetic Adam and Eve Lived Together

AdamEve 386x260 Genetic Adam and Eve Lived TogetherScientists may have tracked down the origins of the biblical Adam–sort of. By studying the Y chromosomes of men from many different populations, researchers have discovered that their male most recent common ancestor (MRCA) lived sometime between 120,000 and 156,000 years ago.

The original ancestor for the X chromosome has been tracked down before by studying DNA carried down through the human race’s female line. This woman probably lived between 99,000 and 148,000 years ago, which correlates nicely with the recent findings. Yet actually tracking the Y chromosome wasn’t easy. Technical limitations previously limited scientists in their search for MRCA.

The scientists used Y chromosomes obtained through the Human Genome Diversity Project and from other sources. In all, it included chromosomes from 69 men in several populations in sub-Saharan Africa, Siberia, Cambodia, Pakistan, Algeria and Mexico. After studying and tracing back these chromosomes, the researchers were able to determine when the MRCA existed.

Our human ancestors in Africa spread out across Asia and Europe and, eventually, into the Americas. Tracing back the genetics of these populations could allow scientists to understand a little bit more about our ancient past.

Almost every man alive can trace his origins to one man who lived about 135,000 years ago, new research suggests. And that ancient man likely shared the planet with the mother of all women.

The findings, detailed today (Aug. 1) in the journal Science, come from the most complete analysis of the male sex chromosome, or the Y chromosome, to date. The results overturn earlier research, which suggested that men’s most recent common ancestor lived just 50,000 to 60,000 years ago.
