Document Summary
Foundations of biological anthropology review for exam 2. Quadrupedal: imi 80-100 (tq > 90 + aq < 90), limbs are equal in length. Bipedal: imi < 70, hindlimbs are longer than forelimbs. Suspensory: imi > 100, forelimbs are longer than hindlimbs. Power: how big of a load that can be moved. Speed: how far the load can be moved. 1st class level system: increase the force arm and decrease the load arm. Quadrupeds have a well-developed deltoid tuberosity in order to support shoulder movements and a flat capitulum. Suspensory primates will have a well-developed capitulum in order to support the elbow during pronation and supination. Protein is an important component to the diet of primates, how might a large primate acquire protein compared to a very small primate. Protein from animal sources: very difficult to get, but easy for the body to break down. Protein from plant sources: easy to get, but very difficult for the body to break down.
