Question

How many years of cumulative evolution separate chimpanzees from humans?

A. 7-8 million years
B. 2-3 million years
C. 130-140 million years
D. 130-140 thousand years
E. 14-16 million years

Answer 1

Answer: A. 7-8 million years

Explanation:

Chimpanzees are considered the closest species to humans and so a logical question to ask is why they haven't evolved as well or rather why they are still chimps and we are human.

The reason is that our ancestors split and went on different evolutionary paths. This split happened sometime 7 - 8 million years ago which therefore represents the years of cumulative evolution that separates chimpanzees from humans.
