Document Summary
"teetering on the brink of catastrophe: skeletal adaptations for bipedality, skull, foramen magnum- hole at the bottom of the center of the skull, in a bipedal animal is more centrally located underneath the skull. The hole is for the spinal cord and goes into vertebrate. Your head sits right on top of your vertebrate, you are then allowed to have a forward facing face. In an ape it is more posterior located for the spinal cord. It allows them to look closer near the ground. (quadrapedalism: spinal curvature, we have a "s" shaped curve. In a biped it helps you balance and hold chest upright (in order to hold organs) They are not necessarily visible but if they are they are just cracks in the ground. This then causes a hard substance called breccia: breccia- concrete like matrix of soil, fossils, shells, this is very hard.
