Researchers have uncovered a new clue about human origins after discovering the oldest known human DNA in a legendary Spanish archeological site called Sima de los Huesos, or the Pit of Bones.. Researchers were able to extract DNA from a leg bone that was estimated to be 400,000 years old. After extracting the DNA from a femur bone, Matthias Meyer, who published his findings in a study in the journal Nature, was able to replicate the entire genome for the ancient human relative.
