Anthropology - Millennium ancestor gets its walking papers

A new study conducted at George Washington University in Washington, D. C. confirms that Orrorin walked upright, a defining characteristic of being a hominin, the primate group that includes humans and our ancestors but not other apes. The data provide really strong confirming evidence that it was bipedal, which reinforces its status as a hominin. Thighbone fossils were analyzed and it was revealed that it was a hominid based on features in the teeth and the upper thighbone, or femur.
