and looks said to belong to the same species?

A species is a group of organisms that are capable of interbreeding to produce a
fertile offspring. Skin colour, looks, and size are all variety of features present in
human beings. These features are generally environmentally controlled. Various
human races are formed based on these features. However, there is no biological
