You keep saying this, but it still have nothing to do with Evolution.
People of different races or speak different languages or have different cultures or customs, etc, none of these mean white Europeans are not more evolved or aborigines are less evolved, biologically.
What constituted as “races”, have more to do with cultures and politics, not biological advantages to survive because of changed environments.
Aborigines are Homo sapiens sapiens, just like the Irish, Germans, Jews, Chinese, Africans, etc; they are not of different species, nor of different subspecies.
How many times must we say this, before it dawned on narrow-minded brain of yours?
