According to this tree, with which other living species do modern humans share their most recent common ancestor? 1. Gibbon 2. To which living species is the common chimpanzee most closely related? 1. Modern Human 3. What is the sister group of all gorillas? 1. Gibbon 4. To which species in this tree are gibbons most closely related? 1. Gorilla 5. According to this tree, are Great Apes (traditionally defined as gorillas, chimpanzees, and orangutans) a monophyletic group, polyphyletic, or a paraphyletic group? 1. Polyphyletic 6. What do these results suggest about the proper taxonomy of primates? In other words, which groupings of primates should we consider taxa and therefore give names to? 1. 7. It has generally been thought that the "knuckle walking" of great apes and the upright bipedalism of humans both evolved after the split between apes and humans. According to this tree, when did knuckle-walking evolve, and when did bipedalism evolve? Does our analysis challenge previous thinking? How? 8. How might we improve our confidence that we have constructed the tree that accurately represents evolutionary relationships among ape species?
