Unusual Y chromosome reveals new male lineage in human evolution


"Albert Perry carried a secret in his DNA: a Y chromosome so distinctive that it reveals new information about the origin of our species. It shows that the last common male ancestor down the paternal line of our species is over twice as old as we thought.

One possible explanation is that hundreds of thousands of years ago, modern and archaic humans in central Africa interbred, adding to known examples of interbreeding with Neanderthals in the Middle East, and with the enigmatic Denisovans somewhere in southeast Asia."
