@YuriABezmenov@diablo_crypto@ShauryaCGhoshal@agenetics1 One thing I would agree is L657 has lot of buzz due to absence in aDNA even of upstream clades. I think the Indic R1a (L657 related) had increased freq in Steppe itself somewhere in Central Asia (broadly unsampled btw), then came along with admix and further increased.
@YuriABezmenov@diablo_crypto@ShauryaCGhoshal@agenetics1 They don't even have a clear fraud position to use. Sometimes it's random Fatyanovo traveller who diffused the haplo, sometimes it's that Scythians brought it in historic era after 900/500 BCE. Both, especially the first one has miniscule chances to have happened.
@DieHenaden@NomadicBrahmin@LuvRabari Most the time Indians kang on Zagros it's actually not pure Zagros, if you remove the ANE out of Farmer, the Iran_N + Anatolian Farmer combo is actual close to "muh Zagros".
@NikhilHDE@Vast_Harrisburg@padh39892@Kautilya02 No, wrong, it's not another wave. They may have had their own V1/V2 (Swat IA samples themselves have high AASI low Steppe cluster). Swat would correspond to V3-4 type profile if we were to compare.
@YuriABezmenov@diablo_crypto@ShauryaCGhoshal@agenetics1 OITards plain dumb and just copy paste his shit blindly from 2021 blogs, or his replies from 2022 on X. Zero original thought formulation. No academic or genetics enthusiast outside of these 6-7 obnoxious retarded OITards think it didn't come with admix, because it's so unlikely.
@YuriABezmenov@diablo_crypto@ShauryaCGhoshal All the blame for this goes to @agenetics1 who back in 2021-2022 and came up with this crap garbage theory (initially it was Y3>Y2 but both were found in Steppe so the cope shifted to next downstream Y27>L657 when he became inactive 3 years ago).
@NikhilHDE@Vast_Harrisburg@padh39892@Kautilya02 That's cause the Swat samples are not V1/V2, so obviously they have lesser Steppe. They correspond to typical mid caste profile. The point is thinking there were some 60% Steppe Aryan post 1500 BC is pure load of bullshit
@NikhilHDE@Vast_Harrisburg@padh39892@Kautilya02 What higher Steppe? Point being made is admix stabilises quick and unless there is outside geneflow the profile doesn't change magically. If V1 ancestral profile was formed by ~1500 bce then it remained so. Steppe admix comes -> stabilises to 30% -> stays so over centuries
@Vast_Harrisburg@NikhilHDE@padh39892@Kautilya02 just seems obvious to me, once admix arrives to stabilises to one level and continuous uninterrupted unless there is unidirectional geneflow from outside, which in our case didn't happen. Swat Iron Age having ~20% Steppe is the proof it stabilised in north to modern levels early
@Vast_Harrisburg@NikhilHDE@padh39892@Kautilya02 That's nonsense. Even if the paternal bias is lower they're part of same cline sphere and autosomally the evidence. The line of thought that there were some high Steppe folks late as Vedic era and didn't dilute to modern levels soon after arrival is itself ridiculous
@Vast_Harrisburg@NikhilHDE@padh39892@Kautilya02 There's nothing called Proto Vedic. Early Vedic were no different from modern north Indian castes in profile. We have direct genetic evidence from Swat confirming this.
@NikhilHDE@padh39892@Kautilya02 That's not how admix comes in. It stabilises rather quick after arrival, instead of staying high for centuries then diluting. Swat had stabilised to ~20% Steppe by 1600 BCE itself, which is comparable to Swat Late IA, Historic, Medieval, Modern levels of Steppe
