Two articles published in the journal “Nature” describe different aspects of a study on various fossil bones including a skull and a jaw uncovered at a site in Jebel Irhoud, Morocco. Several researchers led by the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, studied the bones but also the remains of animals found with them to conclude that those were Homo sapiens of about 300,000 years ago, more than 100,000 years older than the most ancient Homo sapiens fossils so far known.
