When is the common ancestor of humans and chimpanzees thought to have lived? 5. When did the complex behaviors such as the ability to adapt to a wide range of environments and cultural diversification emerge? 6. Describe the major features of a primate skull. 7. Describe the dentition of a primate. 8. What is the dental formula for Old World monkeys and apes? 9. How is the age of a fossil determined using teeth as evidence? 10. What is a phylogenetic tree? 11. When did Austrolopithecus afarensis live in Africa? 12. Why are the fossil footprints found at Laetoli by Mary Leakey important? 13. How do we know that the Laetoli footprints were made by a hominid? 14. When did Australopithecus africanus live in Africa? 15. What is special about the Taung child? 16. What is the primary behavioral difference between Australopithecus species and Homo species? 17. What is it thought that Paranthropus boisei disappeared from the fossil record? 18.

The fossils of H. erectus found near the Solo River in Java are only 50,000 years old. What does this suggest about recent Homo populations? 23. To what species of Homo do modern humans belong? 24.
