It’d be interesting to look at old Indiginal DNA for evidence of Maori interbreeding.
I agree. It would be interesting to look at how it varied by location around Australia – whether the Polynesian influence is stronger in the north and if so by how much.
There is this. “Denisovan ancestry”: http://dienekes.blogspot.com.au/2011/09/widespread-denisovan-admixture-reich-et.html
It appears from this that polynesians, such as Maori, are descended from Australian aboriginals and others. ie. there was interbreeding but it went to other way – from Aboriginals to Maori – and may be very old.
>>Adele’s supervisor, Dr Geoff Chambers found a match between one of the same variant genes for alcohol with people from Taiwan. So it seemed the original homeland of the Polynesian people was in fact Taiwan. Or was it?
When Geoff’s team decided to study the male y chromosome, they got a shock, because it told a completely different story. While the female line is entirely Asian, most of the males came from Melanesia. In fact the men appear to come from PNG, and the women are from Taiwan. So now he believes he finally has the story that makes sense of all the different pieces.
It goes like this… Around 6,000 years ago, a small group of people migrated from mainland Asia and settled in Taiwan. They became a great seafaring culture, and from there they travelled down past Papua New Guinea, they met and took on board local Melanesian guides. The guides were male. And clearly, they must have married and had children. This mix of seafarers reached Fiji, and then eventually moved on again, finally settling in New Zealand just 700 years ago.<<

Any Australian aboriginal DNA in the Maori people would have been from a common PNG ancestor, some of which had migrated across the land bridge to Australia during the last Ice Age. Maori are not directly descended from Australian aborigines.
