An article published in the journal “Proceedings of the National Academy of Sciences” reports a study on fossils of Oreopithecus bambolii, an ape that lived between 6.7 and 8.3 million years ago, in the Miocene period, in today’s Italy. A team of researchers examined the lower part of the torso of an individual belonging to this species of hominoids, part of the most complete skeleton known for this species. The conclusion is that it was bipedal but didn’t walk upright and didn’t climb trees.
