Not really claiming; I was hypothesizing. Unless you can find me a genome of an R1 man with fair-skin, then I might take this theory back. But Loschbur man was haplogroup I2 and had dark skin:

Also, have you taken a look at the map of the haplogroups timeline here on Eupedia?
Attachment 7191
If you look at the timeline, you should notice that Asian Y-DNA R1 is slightly older than European Y-DNA I. So how did Loschbur man; who is haplogroup I2 and is 8,000 years old, have dark-skin as a Mesolithic European? Also...if you observe closely; theoretically, R1b and R1a broke off from R1 at a similar time as I1 and I2 from I.
Also sir, Australoid is merely a subrace of Negroid in the field of anthropology. We are meant to look for
Caucasoid, Mongoloid and Negroid skulls of the deceased. You do realize, that a
Semitic Arab with
darker skin than a
European is considered a Caucasoid as well? Saying "Australoid" in terms of race is like saying "Europeanoid" or something similar.
