Más de 100 años después de su descubrimiento, el neandertal de La Ferrassie sigue proporcionando nueva información que nos ayuda a comprender la anatomía y comportamiento de los neandertales. Este trabajo publicado por la prestigiosa revista Journal of Human Evolution ha sido liderado por el investigador Ikerbasque Asier Gómez Olivencia que actualmente desarrolla su trabajo en la UPV/EHU.

Un equipo internacional, liderado por el investigador Ikerbasque Dr. Asier Gómez-Olivencia, que trabaja en la UPV/EHU, ha obtenido nueva información sobre el esqueleto casi completo del neandertal adulto masculino La Ferrassie 1, descubierto en 1909. Estos nuevos resultados han sido publicados en la prestigiosa revista Journal of Human Evolution.

En este trabajo, el equipo presenta: 1) nuevos fósiles incluyendo todos los huesecillos del oído (martillo, yunque y estribo); 2) nuevas patologías que no habían sido detectadas en trabajos previos, incluyendo una variante congénita en el atlas (primera vértebra cervical) y una fractura de la clavícula; y 3) nueva información tafonómica que es coherente con la hipótesis de que este individuo fue enterrado de manera intencional. En este estudio se han utilizado tomografías computerizadas para poder encontrar nuevos restos y poder caracterizar mejor las lesiones patológicas, lo que apoya el uso que se le puede dar a este tipos de técnicas en las investigaciones de paleontología humana.  [...] UPV/EHU


New technology reveals secrets of famous Neandertal skeleton La Ferrassie 1 | EurekAlert!   
Binghamton University, State University of New York - An international team of researchers, led by Dr. Asier Gomez-Olivencia of the University of the Basque Country (UPV/EHU) and including Binghamton University anthropologist Rolf Quam, has provided new insights on one of the most famous Neandertal skeletons, discovered over 100 years ago: La Ferrassie 1
.
"New technological approaches are allowing anthropologists to peer even deeper into the bones of our ancestors," said Quam. "In the case of La Ferrassie 1, these approaches have made it possible to identify new fossil remains and pathological conditions of the original skeleton as well as confirm that this individual was deliberately buried.

The adult male La Ferrassie 1 Neandertal skeleton was found in 1909 in a French cave site, along with the remains of an adult woman and several Neandertal children. All of the skeletons were interpreted as representing intentional burials, and the finds sparked much public interest at the time regarding just how human-like the Neandertals were. The La Ferrassie 1 skeleton, in particular, has been highly influential in Neandertal studies since its discovery... (Vídeo*)

Actualización. Neanderthals cared for each other and survived into old age – new research

When we think of Neanderthals, we often imagine these distant ancestors of ours to be rather brutish, dying at a young age and ultimately becoming extinct. But new findings show that at least some of these ancient Neanderthals survived into old age – despite suffering from sickness or diseases.

Neanderthals were hunter-gatherers, living in harsh environments, mostly colder than today. And of course they had to face different dangers to modern humans – not only during the hunt, but also because they shared ecosystems with large carnivores such as lions, leopards and hyenas.

But despite this harsh life of the hunter gatherer, our research indicates that some Neanderthals lived to be fairly old and even had some of the signs of age related illnesses – such as degenerative lesions in the spine, consistent with osteoarthritis. Our research also found that an adult male Neanderthal survived bone fractures. And when he died, he was buried by members of his group...
