This is the most beautiful thing, Austronesians conquering all of Oceania, whilst mixing with the Papuans. Apparently it was pretty much Papuan men who were interbreeding with Asian/Lapita-Austronesian women.

And apparently Dai and Austronesians share a common origin before they spit. 'Proto'-Dai must've looked quite Australoid back then I would think.

I don't be very original when I'll conclude that this model is pretty in line with older models bases solely on anthropometry / somatometry.

There is a 2006 paper which already found the same thing - namely that Papuan/Melanesian ancestry in Polynesians is mostly from males: http://mbe.oxfordjournals.org/content/23/11/2234.full

It looks like some conquest, considering that Early Lapita Y-DNA (but not mtDNA) was largely replaced by Papuan/Melanesian Y-DNA. A similar situation as with Indo-European expansion in Europe.

Some anthropologists consider Melanesians as background for Polynesians. There were some older theories but they claimed that in craniological materiał for example from New Zeland there is oldest Australoid /Oceanic Negroid layer. But it turns the opposite. There were some Melanesians maybe even in New Zeland also, but as later newcomers. Maybe anthropologists had problem with datation and automatically used to think about Polynesians as more progressive, hence more recent.

I always knew that the Austronesians mixed with Papuans and Melanesians before they colonized the Pacific.
