habitual terrestrial bipedalism was achieved. While the classification tool of bipedalism remains constant, the alternative classification tools of canine and cranial size provides unreliable means by which to separate hominin and non-hominin ancestral fossils. Such as when dispute occurred involving where in time Ar. ramidus existed within the hominin lineage, or if this genus even belonged to the hominin lineage, when the characteristic of dental morphology was examined. Ar. ramidus possesses a cranial capacity similar in size to species that reside within the lineage of Pan , while simultaneously having morphological cranial parallels to Australopithecus such as more flexion involving planum sphenoideum and greater orbital kyphosis. In conclusion, a proposition for the future is that the development of a pre-determined method for which to distinguish between the hominin and the panin lineage for future and past discovered ancestral fossils needs to be developed. Due to the consistency of bipedalism having the ability to occur, or not having the ability to occur within the hominin or panin lineage respectively, is why it should be the main classification tool used in this method.

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
