Someone explain the aborigines in Australia......very dark skinned, sometimes blue/green eyes and nearly blond hair.

I remember reading a while back that aborigines have a different mutation for blonde hair than what Europeans have. I don’t recall about the eye color.

As for the dark skin - the aborigines are descended from one of the very first migrations of modern Homo sapiens out of Eastern Africa. Over thousands of years they made it to Australia and due to natural selection, having dark skin (protection from the sun) gave them the best reproduction rates and so those traits were kept.

For more learning, do some research on out of Africa Y-haplogroups and mitochondrial DNA mutations.
