Kirk and Russo Publish Study in Journal of Human Evolution

Fri, October 11, 2013

Associate Professor Chris Kirk and postdoctoral research fellow Gabrielle Russo have published a study in an issue of the Journal of Human Evolution that shows a direct link between upright two-legged (bipedal) walking and the position of the foramen magnum, a hole in the base of the skull that transmits the spinal cord.

The study confirms a controversial finding made by anatomist Raymond Dart, who discovered the first known two-legged walking (bipedal) human ancestor, Australopithecus africanus. Since Dart’s discovery in 1925, physical anthropologists have continued to debate whether this feature of the cranial base can serve as a direct link to bipedal fossil species.
