OVIEDO, Spain, April 2 (UPI) -- Scientists say they've determined the age of Neanderthal remains found in a Spanish cave, an important clue in the transition from Neanderthal to Homo sapiens.
Previous estimates putting the age of the remains in the El Sidron cave, one of the westernmost Neanderthal sites on the Iberian Peninsula, at only 10,000 years was the result of inexact measurements, researchers at the University of Oviedo in Spain reported Tuesday.
