Problem 1: Why are the finds at Malapa remarkable compared to other fossil sites in Africa?
Problem 2: Does A. sediba support the "killer ape" hypothesis of human ancestry? Explain.
Problem 3: Linear evolution suggests that there is a ladder, or step-progression, to evolution over time -- one species building and transitioning into another species. A bushy interpretation of evolution suggests multiple overlapping species of hominins, with some species short-lived, and others existing for a long period of time. What type of evolutionary model does A. sediba support?
