HOW DID HUMANS COME TO THIS WORLD

All human beings regardless of their skin, colour, place of origin, and other features belong to a single species. They are known as Homo sapiens.

Human evolution is studied using radioactive carbon-dating methods with the study of fossils and DNA sequences. It has been discovered that both human beings and chimpanzees have evolved from a common ancestor (i.e. from primates).

Human beings (Homo sapiens) evolved from primates in Africa between 100,000 and 200,000 years ago.

Human beings are sociable (i.e. society forming) and upright walking species. The earliest member of the human species  (Homo sapiens) can be traced back to Africa.

Evolution of Homo sapiens

From Africa, humans moved to West Asia, Europe, central Asia, and so on. They then moved to Indonesia, Philippines, and  Australia. At last, they moved to America.

Human evolution began around 4 - 5 million years ago. Those ancestors had a brain capacity of about 450 cc. Homo sapiensare modern humans, which appeared around 120,000 years ago.
