Archaeologists discover ancient remains of a new human species

Scientists, perhaps for the second time in recent days, have discovered a new human species. Researchers claim that the femur of a baby who lived 45,000 years ago, found in France, belonged to an unknown human race. The remains of a prehistoric baby may belong to a previously unknown lineage of Homo sapiens. The bone is different from Neanderthal bone and looks a bit like modern human bone.

Anthropologists in France have discovered a 45,000-year-old baby’s pelvic bone that matches neither Neanderthals nor Homo sapiens. Daily Mail.

The femur of a prehistoric baby was found along with the remains of 11 Neanderthals in the Grottoes du Rennes, later inhabited by Anatomically Modern Humans (AMH), suggesting that the baby coexisted with the now extinct species.

The artifact was compared to two Neanderthal bones and 32 modern baby bones, finding that its shape differs from the bones of both species, but slightly closer to anatomically modern humans, according to the Daily Mail.

“We hypothesize that this is due to its belonging to an early lineage of modern humans, whose morphology is slightly different from modern humans,” the team wrote in a study published in Nature.

The news comes after a separate study showed that an ancient skull that belonged to a child who lived up to 300,000 years ago in China could also belong to a new human species. The fossilized remains, which included a jaw, skull and leg bones, were discovered in Hualongdong in 2019. What puzzled the experts, however, was that this individual’s facial features did not match the lineage that split to form Neanderthals, Denisovans, or us, leading them to suspect that we may be missing a branch on the human family tree.

And that’s what the latest discovery opened, continues the Daily Mail.

Anatomically modern humans appeared in Western Europe about 42,000 years ago, 2,000 years before the Neanderthals died out.

The Grotte du Rennes is a site that was home to both species during the Middle and Upper Paleolithic, but has provided evidence that Neanderthals developed aspects of modern behavior prior to contact with modern humans.

The layers of earth inside the cave give clues as to when the cave was inhabited by Neanderthals and when anatomically modern humans took over the site, but the middle layer contained a small pelvic bone, suggesting that another lineage of humanity also inhabited the structure. .

The baby’s bone was found at the same level as the remains of 11 Neanderthals, the newspaper writes.

This level refers to the Châtelperron cultural complex that existed 45,000-40,000 years ago, followed by the Mousterian culture.

The Châtelperron period was the era when stone tools and flint knives are considered to be a turning point in the evolution of Neanderthals, although some scientists believe that these items were made by early humans.

The pelvic bone of an infant was found to have a very different curvature than that of immature Neanderthal bones, but differed only slightly from that of anatomically modern humans.

The team said the mysterious artifact was in samples taken from modern humans. “Thus, this overlap may indicate variability in the curvature of the ilium [тазовой кости]common to Neanderthals and Homo sapiens,” the study says.

The researchers suggested that the infant was likely a member of an anatomically modern human population that coexisted with the last Neanderthals during the transitional period.

If this hypothesis is confirmed, the team stated that the Châtelperrons may have “arose as a result of processes of cultural diffusion or acculturation, with possible mixing of the population between the two groups.” This, the Daily Mail notes, means that Neanderthals learned from modern humans and used tool making to develop their technology.
