Consider the following mtDNA sequences obtained from chimpanzee and humans in the following geographic regions: Chimp: ATGCGCATTCAATG China: ATGGGCTTTCAATC Ethiopia: ATGGGCATTCAATC England: ATGGGCTTTCAATC Kenya: ATGGGCATTCAATA
Which of the following statements is NOT correct: A. These data depict a higher level of sequence divergence between human and chimp than is to be expected based on overall levels of genetic similarity between human and chimp. B. These data are consistent with the multiregional hypothesis for the origin of humans because the Asian and European sequences are more closely related to each other than either is to the African sequences. C. These data are consistent with an "out of Africa" hypothesis for the origin of humans because the Kenya and Ethiopian samples exhibit an ancestral character state at position 7. D. The African sequences represent older evolutionary lineages than the European sequences because they have one polymorphic site.
