Ethnically speaking why are people from Papua New Guinea lighter than northern Aborigines?

[Oliver109]

Many people from PNG are similar to light skinned African Americans and Caribbean's in colour while Aborigines from the northern territories are as dark as Black Africans and even darker than many Nigerians and Congolese infact, why?

Are they really? The full blooded ones look equally black to me. Self-identified Aborigines in general are lighter because of European admixture.

Theres quite clearly a difference though they are no lighter than Africans from more equatorial areas who aren't exactly pitch black

Ha. Try not to post Papuans who've painted their skin red as examples. The difference is really not clear, regardless if they are lighter or not.

Many remote Northern Aborigines aren't exactly pitch black like that.

Here are some Papuans from Port Moresby, just as "light" as those tribals
As for the lighter Aborigines you posted are they full blooded? it was said that Aborigines from southern Australia were lighter but obviously they have been mixed more in the last century and now the only pure Aborigines are i imagine in the north and possibly the central outback?

I assume they're full blooded, they're from outback & remote Northern Australia. Anyway I'm not interested hair-splitting further, they're all as black as sin.

Obviously all Aboriginals are very swarthy but i would say that they are quite variable in colour, it isn't surprising that ones on the north coast(same latitude as Senegal) are very dark but it is curious how most New Guineans except some people from Bougainville are quite a bit lighter.
