Question

Why the behaviour of monkey is so similar to human?​

Answer 1

Answer:

Humans are primates–a diverse group that includes some 200 species. ... Because primates are related, they are genetically similar. Human DNA is, on average, 96% identical to the DNA of our most distant primate relatives, and nearly 99% identical to our closest relatives, chimpanzees and bonobos.

Answer 2

Answer:

Human and chimp DNA is so similar because the two species are so closely related. Humans, chimps and bonobos descended from a single ancestor species that lived six or seven million years ago. As humans and chimps gradually evolved from a common ancestor, their DNA, passed from generation to generation, changed too.
