"The Ranis cave site provides evidence for the first dispersal of Homo sapiens across the higher latitudes of Europe. It turns out that stone artifacts that were thought to be produced by Neanderthals were, in fact, part of the early Homo sapiens toolkit," said Jean-Jacque Hublin, a professor at the Collège de France in Paris and the former director of the Max Planck Institute for Evolutionary Anthropology where Zavala first began this work. "This fundamentally changes our previous knowledge about the period: Homo sapiens reached northwestern Europe long before Neanderthal disappearance in southwestern Europe."
