Exciting Find Through FamilyTree DNA Find Dates Back 338,000 Years

Exciting Find Through FamilyTree DNA Find Dates Back 338,000 Years
A DNA test on an American hoping to trace his family tree has come up with a stunning result - the roots of the human tree date back much further than previously thought.

Researchers were shocked when they analysed the DNA of Albert Perry, a recently deceased African-American from South Carolina.

'This lineage diverged from previously known Y chromosomes about 338,000 years ago, a time when anatomically modern humans had not yet evolved,' said Michael Hammer of the University of Arizona.

Either interbreeding with Neanderthals or other populations led to the unusual genetic makeup, he said, or humans evolved far earlier than the extant fossil record suggests.

The new divergent lineage - which was found when Mr Perry contacted Family Tree DNA, a company specializing in DNA analysis to trace family roots - branched from the Y chromosome tree before the first appearance of anatomically modern humans in the fossil record.

The DNA analysis proves last common Y chromosome ancestor lived 338,000 years ago, even though oldest fossil of modern man is only 200,000 years old

Or possibly this proves there is a flaw in DNA testing.

I doubt that! DNA don't lie like humans

Actually, I was thinking the same thing. What if there were radiation flares that accelerated the rate of DNA change which would be unaccounted for in the statistical calculations.just a for instance.
