According to a new study by the University of Texas at Austin, anthropologists Gabrielle A. Russo and Liza Shapiro, the ape from seven to nine million years old in Italy did not constantly walk on two legs.

The study, which will be published in future issues of Journal of Human Evolution confirms that anatomical features related to the process of standing on your feet they are uniquely associated with humans and their ancestors.

The discovery brings a new perspective to the debate of the motor capacity of the Oreopithecus”Said Russo, who is participating in postdoctoral research at Northeast Ohio Medical University.

Although it is possible that the Oreopithecus walked on its feet, since apes show short periods of this activity, more and more evidence shows that it did not do so frequently.”.

The researchers analyzed the ape fossil to see if he had consistency in the spine to be able to walk upright. They compared measurements of the lumbar vertebrae and the sacrum (a triangular bone placed at the base of the spine) with those of humans, hominin fossils and pieces of tree-dwelling mammals, including apes, sloths and an extinct lemur.

The lower part of the column serves as the base for test your bipedalism hypothesis Since the lumbar vertebrae and the sacrum of humans have different features that facilitate the transmission of body weight while making it possible to walk upright, confirms Russo.

According to the findings, the lumbar vertebrae and the sacrum of the Oreopithecus It is different from that of humans, and more similar to that of apes, which makes it impossible to stand on your feet.

The lower part of the human spine is specialized for bipedalism, which is why it is a fundamental area to evaluate if this way of moving, exclusive to humans, also occurred in the Oreopithecus«Says Shapiro, professor of anthropology. He also adds that so far the debate on the locomotor apparatus of the Oreopithecus has focused on the extremities and pelvis, but no one had ever evaluated the controversial claim that his lower back was like that of humans.

I am currently studying Journalism and Audiovisual Communication at the Rey Juan Carlos University, which has made me inclined towards the international section, including the study of languages. For this reason, I do not rule out teaching myself. I also like to practice physical exercise and spend a pleasant time chatting with my acquaintances and with new people. Finally, I enjoy traveling to know the authentic culture of each region of the world, although I admit that before I need to find out as much as possible about the place I'm going to visit, to fully enjoy the experience.
