A miniscule bit of DNA from an African American man now living in South Carolina has been traced back 338,000 years, according to a new study.
The man’s Y chromosome — a hereditary factor determining male sex — has a history that’s so old, it even predates the age of the oldest known Homo sapiens fossils, according to the report, published in the American Journal of Human Genetics.
The fellow’s chromosome turned out to carry a rare mutation, which researchers matched to a similar chromosome in the Mbo, a population living in a tiny area of western Cameroon in sub-Saharan Africa.

Still, Hammer said, “It is likely that other divergent lineages will be found, whether in Africa or among African-Americans in the U.S. and that some of these may further increase the age of the Y chromosome tree. There has been a lot of hype with people trying to trace their Y chromosome to different tribes, but this individual from South Carolina can say he did it.”
The study has even further implications. It strengthens the belief that there is no “mitochondrial Eve” or “Y chromosome Adam.” 1st African American Man Dates Back 338,000 Years : Discovery News
All of humankind, as a result, did not descend from exactly one pair of humans that lived at a certain point in human evolution.
