Which of the following describes the order in which traits and practices evolved in human ancestors?
Tomtit [17]

Answer:

The order of development has been large brains, bipedalism, tool use, modern behavior.

Explanation:

A is not correct because the human ancestors had large brains before they become bipedal, which is not weird considering the fact that all primates have proprtionately large brains, even for mammals.

B is correct because the large brains were already a trait of the human ancestors, with the change of environment they developed bipedalism, with the further growth of the brain and anatomic changes in the fingers the humans developed tools, and last but not least came to modern behavior.

C is not correct because bipedalism occurred before the usage of tools.

D is not correct because the tool usage did not occur at the beginning of human evolution, but several million years later.

E is not correct because the bipedalism occurred later than the large brains, and the modern behavior came the last, not in the early stages.

andrew-mc [135]

Answer: (D)

That also means that biotic factors everywhere including the surrounding area need to be thought of in this sense so that they are able to survive in the environment they are in.
