Extended data

Race is a human group with the same genetic characteristics.

Race is also called race. In biology, all human races belong to the same species, namely Homo sapiens.

Different races are equivalent to several varieties under one species.

Although there are differences in skin color, eyes, hair color, hairstyle, head shape and height among different races, these differences are caused by long-term adaptation to the local natural environment and long-term isolation from human beings in a certain area.

At present, only melanesians and Papua people in Oceania are still the main residents of the islands.
