Thigh bone reveals timing of human-Neanderthal sex

(NEWSER) – It's no surprise that modern humans and Neanderthals used to get it on— most people of Eurasian descent are, genetically, 1.6% to 2.1% Neanderthal. The question has long been when they did, with a wide estimate putting it between 37,000 and 86,000 years ago based on the DNA of people alive today. But now the complete genetic sequencing of a man's thigh bone, which is itself roughly 45,000 years old, suggests that we took a dip in the Neanderthal gene pool 50,000 to 60,000 years ago, reports National Geographic. The bone was found in 2008 in western Siberia; it's the oldest human bone to have been recovered beyond Africa and the Middle East.
