''' HUMAN* EVOLUTION HUSTLE '''

MOROCCO : RESEARCHERS HAVE ANNOUNCED that fossils discovered in a Moroccan quarry are about 773,000 year old - filling a critical gap in the understanding of how human beings came to be.  The find has the potential to revise theories on early human evolution.

The bones and teeth of hominins, primates leading up through the human lineage that branched off from chimpanzees and walked upright, are described in a study published this month in the journal Nature.

The fossils come from Grotte a Hominides, a cave site in Casablanca that may have been a den of prehistoric carnivores.

The site offers a window into prehistoric coastal ecosystem, where the Atlantic meets a varied terrain of sand dunes, karsts and marine terraces.

The region once was a vibrant habitat of wetlands and swamps that supported abundant wildlife, with panthers prowling the savannas and hippos, crocodiles, hyenas, and jackals all sharing the muddy shores and surrounding areas.

The assemblage of hominin remains featured in the study includes a nearly complete adult jawbone,  half an adult jawbone, the jawbone of a child, several vertebrae and isolated teeth.

These remains are distinct from the fossils of the nearby Jebel Irhoud site, which at 300,000 years of age are currently the oldest known evidence of our species, Homo sapiens.

These rare, precisely dated bones are significant because they come from a period in the African Fossil record from 800,000 to one million years ago from which similar specimens are yet to be found.

This time frame is crucial as it is when the African lineage leading to Homo sapiens is thought to have diverged from Eurasaian hominins that produced Neanderthals and Denisovans.

The Grotte a Hominides bones turn out to be strikingly similar to those of Homo antecessor, a species characterized by a mix of primitive and modern facial features and identified in the 1990s at a site in Gran Dolina, Spain.

The Spanish fossils, which are of a comparative age, pushed back the known date for human presence in Western Europe by hundreds of thousands of years.

The Gran Dolina specimens challenged a theory that Homo sapiens originated in Africa and then replaced other hominins as they migrated to the rest of the world.

Instead, they were offered as support for the idea that early hominins migrated out of Africa and evolved into distinct groups across Asia and Europe in that evolutionary scheme, Homo antecessor was seen as a potential link between earlier African ancestors and the later European Homo sapiens and Neanderthals.

While distinct from the Spanish specimens,  the Moroccons fossils also exhibit a mosaic of traits, indicating that the last common ancestor of these lineages existed on both sides of the Mediterranean and that the divergence between African and Eurasian hominin branches was already underway when the individual lived.

Jean-Jacques Hublin, an anthropologist at the Max Planck Institute for Evolutionary Anthropology in Germany and the lead author of the new paper, argued that this evidence supported a deep Arican origin for Homo sapiens and countered theories of a Eurasian origin for our species,
