JameL: It is a bit true, but the the Native Australians are same kind of people, but not same people.
To easly understand, I ewill now describe the four human races (or what you will call it):
Europid: Lives in Europe, Middle Eastern, North America and some in India and South America. Have soften straight hair, some of them (like me) have blue eyes.
Negroid: Lives in Africa, have black color skin and crusaly (right?) hair.
Mongolid: People from Asia, some of them emigrated to South America and became Natives there. Have "slim" eyes.
Australid: The Native Japanese and Austalians.
Did you understand now?
