Polynesian autosomal DNA question

What ancient mix are they? australoid+Mongoloid? or what?

Yeah. Here is a native Samoan in Gedrosia K6 calculator:

2 Ancestral_South_Eurasian 28.24
3 Sub_Saharan 1.45

By comparison an Australian Aborigine in Gedrosia K6:

This is the component that indians have and peaks in southernmost part of the subcontinent?

Yeah. ASE admix, I think that it also peaks among Andamanese Negritos:

About 3/4 East Asian + 1/4 Australoid.

Probably closer to 2/3 + 1/3 because Tibetans are partially ASE themselves, IIRC.

===============

There is also a recent publication about Polynesians (it models them as 3/4 + 1/4, but it is about Tongans, not about Samoans - maybe Samoans have slightly different admixture proportions):

"Genomic insights into the peopling of the Southwest Pacific" (http://sci-hub.cc/doi/10.0000/www.nature.com/nature/journal/v538/n7626/nature19844), 2016.

Oh and Polynesian Y-DNA is mostly Australoid, while their mtDNA is mostly Mongoloid.

So it looks like conquest of Lapita Culture by Papuan slayers = modern Polynesians.

Maybe, it's something around 70% either way. We lack a fine sub structure between Australoid/Onge/Papuan and generally in East Asians. When Dai, Han or Ulchi, score close to 100% E.Asian they are certainly made of different ancestral genomes that we lack of, it's bit like Europeans scoring "100% European".

[Peterski]

What is interesting is that Lapita culture was 100% Mongoloid while modern Polynesians only 70%. And Y-DNA of modern Polynesians seems to be mostly of Non-Lapita origin. So contrary to old theories, it was most likely not conquest of Papuans or Melanesians by East Asians, but probably the other way around:

I am Polynesian however score some Native American. What does this mean?

Polynesians from Easter Island and natives of South America met and mingled long before Europeans voyaged the Pacific. One study by Erik Thorsby suggests Native Americans likely arrived on Easter Island shortly after Polynesians. Other scientists’ state Pacific currents and Polynesian mastery of the waves make it more likely that the Polynesians were the voyagers. They may have sailed to South America, swapped goods for sweet potatoes and other items—and returned to their island with South American women. It is possible those Polynesians on Easter Island traveled back west to trade with east Polynesian countries. As you can see there are many possibilities.

You may have had a Native American ancestor, but unless you score a good chunk of it on an autosomal test, it will be hard to confirm. The study by Thorsby stated that in the 27 living Easter Islanders who were tested, there was around 8% Native American in their genomes.

This article probably explains the South Indian - Oceanian connection:

"Genetic study reveals some Aetas and Indians share ancient ancestry":

http://www.gmanetwork.com/news/story/328467/scitech/science/genetic-study-reveals-some-aetas-and-indians-share-ancient-ancestry

Aetas are a Negrito ethnic group from South-East Asia (the Philippines).

It seems that Negrito groups also share this purple component at K14:
