Do genetically 50% South Asian 50% East/SE Asian ethnic groups existed in South Asia?

[Tsakhur]

It is already known that a lot of SE Asians tend have on average around 5-25% or more South Asian ancestry with some ethnicities such as the Rakhine of Western Myanmar and Acehnese of Northern Sumatra likely possessing up to 30-40%. But I wonder are their any ethnic groups in South Asia who are in the middle aka 50-50 mixes between South Asians and East/SE Asians? I heard of some recent mixes such as Chindians aka half Indian half Chinese in places like Singapore or Malaysia but they seem to be a rather recent phenomenon but I am eager to know do such ethnic groups/populations like this exist in the Indian subcontinent since ancient times?

I would say the Nepalese are mix of south asian and east asian

Nepalese are mostly skewed on one or another different genetic poles/sides due to caste endogamy. Really hard to find tribes that are in the middle from Nepal.


Newars of Kathmandu valley, Nepal are in the exact middle. They look like half Gangetic Rajput (or mix of Gangetic Rajput-Vaishya) - half Chokhopani.

Nepal Tharus are also around similar since Chokhopani itself is one-sixth South Asian like.

Why is it hard to find such tribes who are exactly intermediate?

Their East Asian ancestry is Tibeto-Burman-like?

Sorry for my ignorance but I noticed Chokhopani tend to be prefer in estimating the amount of East Asian ancestry in some South Asians rather than Mebrak or Samdzong. Why is that?

Do you know any groups in the subcontinent who are close to half South Asian half SE Asian (Austroasiatic, Tai-Kadai, Austronesian, etc)?

There's a tribe/caste endogamy among Nepalese and strong identification with respective racial groups that prevented extensive mixing. I don't suggest Samdzong becoz it's from 1500 BP which could bear additional non-TB admixes.

Half SE Asian could be found in East India Jharkhand-Bihar-Bengal region; Idk honestly. Maybe try PCA plots to find.

I am only using NPL_Chokhopani_2700BP as a East Eurasian source. Kusunda is a language isolate and not linked to any other language in South Asia.

Acehnese probably aren’t 30% South Asian on average lol. And Chokhopani definitely isn’t 1/6th South Asian (unless there’s some AASI and Iran_N ancestry in there I don’t know about)

[Kapisa]

No because they are temporally not consistent.
