The world race is often wrongly used. For example, the Jews are not a race, but a religious and cultural group, who, in racial terms, are exactly the same as the Nazis who persecuted them. Many scholars say that there is only one race-the human race. However, the human family can be divided into several groups according to such features as skin, eye color and hair type. The four main groups are: Caucasoids, Mongoloids, Negroids and Australoids, who include Australian Aborigines.
