Step One: Anatomical Developments
Match the following anatomical developments (A-J) with the number where they occur on the Hominin Anatomy Phylogeny (below).
A. decreased prognathism, moderate sized molars, phalanges not curved (derived), Found in South Africa, still relatively small brain (~450cc)
B. canine reduction, lower jaw tooth row shape intermediate between parallel and parabolic, have footprints explicitly displaying bipedal patterns, curved phalanges
C. further brain expansion, decrease in teeth size, decrease in brow ridges, flattening of the face, mental eminence, vertical forehead
D. megadontia complex (huge molars, jaws, and chewing muscles), slight increase in cranial capacity (410-530cc)
E. femur and pelvis indicate capable of bipedalism
F. brain expansion, megadontia reduction, smaller less projecting face, smaller jaws
G. occipital bun common, retromolar space, robust postcrania, relatively short limbs
H. further brain expansion, reduction in teeth, face, and jaws, increased brow ridges, increased body size
I. loss of honing complex, obligate bipedalism, curved phalanges (primitive), parallel tooth row shape
J. foramen magnum position indicates likely capable of bipedalism
