The DNA from the 45,000-year-old bone of a man from Siberia is helping to pinpoint when modern humans and Neanderthals first interbred, researchers say. Although modern humans are the only surviving human lineage, others once lived on Earth. The closest extinct relatives of modern humans were the Neanderthals, who lived in Europe and Asia until they went extinct about 40,000 years ago. Recent findings revealed that Neanderthals interbred with ancestors of modern humans when modern humans began spreading out of Africa 1.5 to 2.1 percent of the DNA of anyone living outside Africa today is Neanderthal in origin. It remains uncertain when interbreeding between modern humans and Neanderthals occurred. Previous estimates of these events ranged from 37,000 to 86,000 years ago. [See Photos of Humanity's Closest Relative] To help solve this mystery, scientists analyzed the shaft of a thighbone found by an artist and mammoth ivory collector, Nikolai Peristov, on the left bank of the river Irtysh near the settlement of Ust'-Ishim in western Siberia in 2008. They calculated the age of the man's bone to be about 45,000 years old. "This is the earliest directly dated modern human outside of Africa and the Middle East, and the oldest modern … Continue reading
