a. Members of the group called australopiths were the first to migrate from Africa.
b. Homo sapiens originated in Africa.
c. Sahelanthropus was the earliest hominin.
d. Chimpanzees are more similar to gorillas and orangutans than to humans.

Accepted Answer

Hello everyone here We have a question telling us scientists were able to identify divergence from a common african ancestor by comparing the blank of males from different geographic regions. So first up we have mitochondrial D. N. A. This is passed on from mother to fall to sons and daughters. So A. Is incorrect. B. X chromosomes both males and females have X chromosomes so that is incorrect. See why chromosomes mutations on the Y chromosome can serve as markers for tracing the ancestry and relationships among males alive today. And this is because unlike autos OEMs that undergone genetic recombination, why chromosomes are transmitted from fathers to sons. So we can compare the Y chromosome the male from various geographic regions and infer divergence from a common african ancestor. So our answer is C. Y chromosomes. Lastly we have de autos OEMs autos OEMs undergo genetic recombination so that wouldn't help us track. So our answer is C. Y chromosomes. Thank you for watching. Bye.
