Neanderthals were walking upright like today's people

The reconstruction of the pelvis and spine of the Neanderthal skeleton shows that Neanderthals can walk upright like modern people.

Visual reconstruction of the pelvis and spine of a Neanderthal skeleton in France, which is almost completely preserved in France, shows that the Neanderthals can anatomically walk vertically like modern people. An upright and balanced posture is one of the features that define Homo sapiens. On the contrary, the first reconstructions for Neanderthals in the 20th century were in a way that they walked in a partially upright manner.

These reconstructions were based on an old male Neanderthal, who was almost completely preserved in La Chapelle-aux-Saints, France. Scientists have known since the 1950s that the perception of the hunchbacked caveman created for Neanderthals is not true. Both evolutionary and behavioral similarities have been known for a long time. Martin The fame of focusing on differences has come back, mod says Martin Häusler, an evolutionary medicine specialist at the University of Zurich. For example, in recent studies, several isolated vertebrae were used to show that Neanderthals did not have a well-developed double S-shaped spine.
However, the visual reconstruction of the La Chapelle-aux-Saints skeleton now provides evidence of a contrary. This anatomical model was directed by Martin Häusler. Louis created a computerized research group by Erik Trinkaus of the University of Washington. The researchers were able to show that this individual and also the Neanderthals had a curved lumbar area and neck, just like today's people.

Sacrum, vertebrae and signs of wear Researchers have discovered that the sacrum is anatomically identical to modern people when performing pelvis reconstruction. This led to the conclusion that the Neanderthals had a lumbar region at a well-developed level of curvature. When they combined the individual lumbar and cervical (neck) vertebrae, they were able to realize that the spine curvature was even more obvious. Spinous processes, the close distance between the bony protrusion at the back of each vertebrae, become apparent, and at the same time, the wear marks occurring by the spine curl. Recognition of similarities The traces of wear in the hip joint of the La Chapelle-aux-Saints skeleton also show that Neanderthals are anatomically steep as modern people. Pel The pressure in the hip joint and the pelvis is no different from the one we're in, H says Häusler. This finding is also supported by analysis of the spine and pelvic bone remains of other Neanderthal skeletons. . There is very little evidence that the Neanderthals have a fundamentally different anatomy, H says Häusler. It is time to recognize the basic similarities between Neanderthals and modern anatomically modern people, and to direct our focus to the biological and behavioral changes that have emerged in the late Pleistocene, and he explains.
