Question

Explaln the evolution of four great apes on the time period scale.

Answer 1

Gibbons diverged from the main line about 10 million years ago; orangutans about 8 million years ago; ancestors of gorillas and chimpanzees about 4 million years ago; and gorillas and chimpanzees separated about 2.3 million years ago. These are evolutionary divergence estimates, not a sequence in which one living ape evolved from another.
