Question

when the humas live in the earth​

Answer 1

Answer:

Some disagreement exists about the scientific definition of human. Some scientists date the Homo genus back only 100,000 years while others go back 11 million years and include Neanderthals, chimps and gorillas. Most say early humans first appeared between 2–3 million years ago.

On the biggest steps in early human evolution scientists are in agreement. The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs.
