Family Tree Test (changes human history?)

Recently, a cousin had me submit a DNA sample to these people. This story is more interesting to me as a result. would like feedback from the resident scientists.

DNA traced to Mbo, a population living in a tiny area of western Cameroon
Proves last common Y chromosome ancestor lived 338,000 years ago, even though oldest fossil of modern man is only 200,000 years old

'This pushes back the time the last common Y chromosome ancestor lived by almost 70 percent.'

This time predates the age of the oldest known anatomically modern human fossils.

The fossil record dates back about 200,000 years, said Hammer.

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.
