Baffling 400,000-Year-Old Clue to Human Origins. Scientists have found the oldest DNA evidence yet of humans’ biological history. But instead of neatly clarifying human evolution, the finding is adding new mysteries. The fossil, found in Spain, had previously seemed to many experts to belong to a forerunner of Neanderthals. But its DNA tells a very different story. It most closely resembles DNA from an enigmatic lineage of humans known as Denisovans. click through

This recent and relatively quick process of natural selection suggests that the traits which spread rapidly were advantageous within that environment.
