Gnxp has revelation from "pconroy "
Interestingly the inhabitants of Tierra Del Fuego were also phiosiologically unlike other Native Americans, and resembled Australoids more. Many of their initiation ceremonies were similar to Australian Aborigines too.
Curiously some early Cro-Magnon skulls from Croatia IIRC also fell way outside the range of features of modern Europeans and were more like Australoids.
Therefore I'm sticking to my idea that Australoids = Neanderthals, who have undergone some evolution in the last 40,000 years, from their classical feature in Europe.
IIRC, certain brain formation alleles (ASPM?) were at high levels in France (>50%), and in neighbouring areas at around 20-40%, but in Papua-New Guinea, were at 55%. So, if Neanderthals hybridized with early moderns in France or maybe Iberia
Of course there are people who may not have interbred with moderns in the areas other than Australoids, they are the Negritos. The Semang are one such group. Another group are the Negritos of Australis or Barrineans and the Negritos of the Andaman Islands. Of these the Sentinelese
are the most interesting, as the link above says:By their long-standing separation from any other human society they are among the most isolated and unassimilated peoples on Earth http://en.wikipedia.org/wiki/Uncontacted_peoples
For what it is ?
