Anthropologists confirm 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.

On the bottom of your skull, there is a distinctive hole. The technical name for the opening is the foramen magnum the great hole that the spinal cord and other critical soft tissues run through.

The foramen magnum, a large opening at the base of the skull, is critical in neurosciences, forensic anthropology and bioarchaeological research. Recent investigations into its morphometry have ...

Another look at the foramen magnum in bipedal mammals. Journal of Human Evolution, 2017; 105: 24 DOI: 10.1016/j.jhevol.2017.01.018 Gabrielle A. Russo, E. Christopher Kirk.

The key feature is a forward-shifted foramen magnum, the hole in the bottom of the skull through which the spinal cord passes. Scientists argue the adaptation ensured the brain remained centered ...

Chiari malformation type I (CMI) is a congenital neurological disorder characterized by the herniation of the cerebellar tonsils through the foramen magnum, which impairs cerebrospinal fluid ...

The present paper is concerned with the phenomenon of interspecific allometry in primates and its relationship to the concept of adaptation. A metrical study of the primate skull was performed to ...

ABSTRACT: The postcranial skeleton of the Late Miocene hominoid Sahelanthropus tchadensis is unknown; because of this the possibility of bipedal posture and locomotion has been based on cranial ...
