Scientists have uncovered what they believe is the oldest human DNA sample ever found, a discovery that could help unravel the mystery of how humans spread out over the planet. Phys.org reports that DNA came from a Homo Sapiens femur bone that was found accidentally on the bank of a west Siberian River in 2008; it is believed to have belonged to a man who died about 45,000 years ago. The DNA found in that bone holds traces of Neanderthals, a cousin of early humans who lived nearby in Eurasia before suddenly disappearing.
