New DNA evidence has revealed that the oldest known common male ancestor is 340,000 years old, more than twice as old as previous estimates. News 92 FM’s Norm Uhl has the story:
After an African-American man named Albert Perry died in South Carolina, one of his relatives submitted a sample of his DNA for analysis. New Scientist magazine reports that all previously compared DNA samples pointed to a common Y chromosome traced back to man who lived between 60,000 and 140,000 years ago. But Perry’s DNA sample didn’t match.
Geneticists at the University of Arizona conducted further tests and found that Perry’s DNA matched up with 11 men who all lived in one village in cameroon. the finding suggests there may have been an earlier species of humans that went extinct—but not before interbreeding with the more modern version of man.
