This sounds like a no-brainer, but the scientific debate has lingered for almost 90 years. Finally, the relationship between the foramen magnum (the hole at the base of your skull through which the brain stem transmits) and bipedalism has been proven beyond doubt.
This is important to us bigfooters in regards to future cranial discoveries of apes, and particularly hominids and our ancestors. As we learn more about bigfoots, humans, and our relationship on the primate family tree, we need to know where the big hairy guys belong. Are they hominids? Are they Silvapithecus offshoots? Are they something else entirely? Only by learning about our ancestors can we shed any light onto these mysteries. Certainly, chief among the concerns about possible ancestory would be bipedalism.
Anthropologists Confirm Link Between Cranial Anatomy and Two-Legged Walking
Sep. 26, 2013 — Anthropology researchers from The University of Texas at Austin have confirmed 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.
