Question

1) One of the reasons that the later record of human evolution from about 500,000 to 40,000 year ago is so difficult to sort out is because

A. no fossil hominids are found in direct context with stone tools B. the fossil record for this time period is inadequate C. mostly sites are known by archaeological evidence only D. few reliable dating techniques can be used during this interval

2) Supporters of the "multireginal" hypothesis for modern human origins point to evidence for the long-term continuity of certain anatomical traits among many human populations, but "out of Africa" proponents counter this claim by arguing that A. these traits are likely to be symplesiomorphies rather than synapomorphies B. these traits could represent independently evolved responses to climate-related selection pressures C. these traits are likely synapomorphies rather than symplesiomorphies D. these traits have no adaptive value E. A and B

3) The "out of Africa" hypothesis for modern human origins would be __ if fossils that could be attributed to this species were found in Africa and dated to 150,000 years ago. A. (there would be no impact) B. strengthened C. unchanged D. invalidated

4) The "out of Africa" hypothesis for modern human origins would be __ if fossils that could be attributed to this species were found in Asia and dated to 250,000 years ago. A. strengthened B. unchanged C. invalidated D. (no impact at all)

5) The evolution of the brain is difficult to study because the only information available from the fossil record is that of the endocranial volume.  Still, the is evidence suggests that A. brain size must be considered relative to the size of the body B. modern humans demonstrate an increase in relative brain size above that of archaic Homo sapiens C. brain size is not relative to the size of the body D. brains decrease in relative size from neanderthals to modern humans E. A and B 6) The land-bridge between Asia and North America at what is now the Bering Strait allowed the first people into the New World between 50,000-100,000 years ago. True
False
7) The out of Africa model of human origins states that anatomically modern Homo sapiens evolved A. in a number of different regions at the same time B. multiple times in the same place C. once, in one place D. in a number of different regions at different times 8) When compared to other hominin species, Homo sapiens appear to have developed more efficient foraging methods and higher degrees of social cooperation. True
False 9) Which of the following is/are changes identified in the skull of modern Homo spaiens when compared to early hominin species? A. reduced supraorbital torus B. development of a "chin" C. rounded overall cranial shape D. decrease in midfacial prognathism E. All of these F. A and B only
