1. Average genetic heterogeneity decreases in populations further away from the African continent in accordance with the migratory history of anatomically modern Homo sapiens. True False 2. Naturalists like Comte de Buffon and Johann Blumenbach proposed that a. different groups of people had different origins. b. differences in environment could lead to biological changes between different groups of people. c. humans are not closely related to any living animal species. d. the differences between people are a result of their desire to improve or stay the same.

1/ Because mating occurred between humans and Neanderthals, researchers unanimously agree that they must have had peaceful interactions and politely shared resources. A. True B. False 2/ In regard to human origins, the Multiregional Continuity model explains that A. modern humans left Africa and continued to destroy the lives of all other hominins. B. modern humans evolved because of gene flow that occurred across Africa, Europe, and Asia. C. modern humans migrated to different regions, but never mated with the Neanderthals. D. modern humans originated in Asia, then spread to other regions of the world.

The surprisingly low rates of genetic differences between different current human populations (about only 6.5%) and the fact that most genetic diversity occurs person-to-person within a population rather than population to population points to: A. a common origin of Homo sapiens sapiens in Africa from a small number of people B. a fairly high rate of gene flow between human populations C. a fairly short time, perhaps 200,000 years existing as a new species in Africa D. all of the above
