Polynesian DNA in South Asians

[SardiniaAtlantis]

So I have been watching a number of DNA testing videos, and whenever South Asian people have their DNA tested it seems that a majority of them score at least a small amount of Polynesian. This to me is very interesting, doesn anyone have any idea as to why that may be?

Aren't Australoids related to Polynesians?

Some Polynesians have Austroloid admixture but they have distinct markers.

I uploaded Andamanese Negrito on GEDmatch Genesis - kit number UC8931952 - and he scores South Asian in a lot of calculators:

Here is how they look like: https://theuniverseandman.files.wordpress.com/2012/09/3p29xkwpauy98-y4c1fi-negrolitos-4a.jpg

I don’t believe the two things are related.

Well, the point is that Indians are partly descended from Onge-like Negrito groups.

And this is also the case with your question - Polynesians have Indian-like DNA.

These DNA tests results are example of confusing chickens with eggs:

I am not so sure about that because Polynesian DNA markers recognized by results are those inherited from Taiwanese aboriginals which look nothing like australoids or negritos and are far removed from them.

Well this is a classic "chicken or egg" dilemma - what was first?

I don't think that Indians have actual Polynesian admixture. It is shared ancestry.

And it is either Onge-like (Andaman-like) shared ancestry, or shared Mongoloid ancestry (North-East Indians have some Mongoloid).

Aren't Australoids related to Polynesians?

Polynesians are mixed race - they emerged from mixing of Lapita Mongoloids with Australoids (Papuans or Melanesians):

I am half Indian, my mum had some Polynesian DNA with AncestryDNA actually but it was only like 2%. My 23andme test didn't show any for me though.

There are Austroasiatic-speakers in North-Eastern India, and they have Mongoloid admixture:

Taiwanese Aboriginals in Eurogenes K36 score: Malayan, Indo-Chinese, South Chinese (some of them also minor East Asian).

For comparison Andamanese Negrito also scores Malayan (so there is shared DNA between Taiwanese Aboriginals and Onge):

Did your mum also have austronesian?

[Peterski]

Did your mum also have austronesian?

Do they have "Austroasiatic" among their reference populations?

[arkas]

Did your mum also have austronesian?

For ancestrydna? I don't think so. Her original results gave her a very high East Asian percentage, 21%, not sure if that counted as Austronesian but that all decreased since the update.

[Borealis]

Eastern non-African ancestry, simple as that. It's also very common for them to score east Asian, same reason.

[Thambi]

Those were the results before the update. The updated ancestrydna results show most desis getting south asian with a split of gujarati and south asian.

Basically before the update, they used to have punjabi and sindhi groups as references for south asian. Thats why many pakistanis used to get 95%-100% south asian on those tests while indians used to get 85% or so with rest being east asian/pacific islander due to the ASI shift compared to pakistanis. It gets complicated with some groups like bengalis though since they have good amount of ASI and actual east asian. they got results with 20% East asian on AncestryDNA.

I used to have 8% east asian and 5% melanesian. Most south asians showed melanesian, which is related to australian aboriginal group, and thats basically shared dna with south asian native groups. Now after the update most south asians get almost nothing besides south asian.

East asian stretches from east siberia to indonesia so Indians get higher east asian than pacific islander due to the SE asian shift as many tribes in india, like peterski pointed out, are quite similar to austronesian groups in mainland SE asia. After that they get melanesian, then polynesian. This is due to having more affinity towards australian aborigines than tongans/samoans.

I'd guess it relates to the wider Austronesian realm. Asia-->South East Asia-->Polynesia

[Iloko]

could maybe just be SE-asian-like admixtures or 'austronesian" dna,,,i believe there may be a lil austronesian influence in some parts of south asia..i'm guessing not all that much though unless we're speaking of 'NE-india' and such

but what percentages do they seem to score from what you have seen?

but if we're talking about thailand, burma, and cambodia...there there IS some austronesian/taiwanese-aborigine-like admixture in there for sure
