Looking at pigmentation genes is interesting, but many of these
are known to have been under selection. So if there has
been selection in India since ANI/ASI mixing they are not
good choices to figure out mixing proportions.

This is a somewhat off-topic question, but how far over on the "light-complexion" end of the Bell Curve do Indians have to be for their fellow Indians to regard them as "non-Indian looking?" For example, I have read some internet comments (Sepia Mutiny, etc.) from Indians who regard GOP gubernatorial contender Nikki Haley as "non-Indian looking."

nick, yeah. what would i would be curious about is if derived slc24a5 lines up perfectly with your estimates of ANI. if so, that's awful suspicious.

Razib,

But another issue is that Andronovo Culture individuals are part of the ancestry of the invading Indo-Iranians, the other part was BMAC

That should be BMAC

"Perhaps Europeans changed after ANI left. Or perhaps ANI changed when it arrived in India."

Or perhaps they weren't Europeans at all? Perhaps they were Middle Easterners - the same Middle Easterners who brought agriculture to Europe?

The scenario of a small South Indian deme constantly surrounded by an ocean of North Indians does not really seem to fit the conventional wisdom about Aryan migration (relatively small tribes taking control of a larger indigenous population, even in the North).

Perhaps the North Indians were actually the stock of the Indus Valley folks, presumably the first people who grew enough to have such a significant impact on India as a whole? That would imply that both the Harappans and the Aryans were actually of "Foreign" (European or Middle Eastern) descent. If confirmed, I predict mass fits of hysteria in the Hindutva rank and file...

jan,

I am thinking that the Indus Valley civilization was populated mostly by people of Middle Eastern descent - perhaps relatives of the Elamites. By this model, the pre-agricultural South Asians did better than the pre-agricultural Europeans, who are even less well represented in the modern European genome.

would be interesting for preform the same analysis as here on northern europeans.

Razib,

Based on what I've seen on 23AndMe of Northern Europeans, Scandinavians show affinities with South/Central Asians, whereas Southern Europeans show affinities with Middle Easterners.

autosomal? not just Y?

Right, automsomally

I share genomes with about 250 people, and my top 10 overall autosomal matches on 559259 SNPs are:
1. Irish-English-Dutch
2. Swedish
3. Irish
4. Swedish-Scots-German
5. Irish-German
6. English-German
7. Irish
8. English
9. Cornish-English-Irish
10. English-Spanish


But on certain traits my matches are not as expected, say for instance the 502 SNP's tested under pigmentation, my top matches are:
1. Estonian
2. Finnish
3. Hungarian
4. English-French-Italian
5. Finnish
6. English-Scottish-Irish
7. Russian (Google co-founder)
8. English-German-French
9. Cornish-English
10. English

So my overall matches are mostly Irish, English, Swedish and German as might be expected, while my pigmentation skews towards North Eastern Europe.

1) People from Northeastern states have had situations when they were not considered as 'Indian', due to thir looks.
2)We see a significant number of 'Fair' south indians and very dark Sikhs and other north Indians.

even i have a tendency to "look asian" in some photos, though i'm obviously brown. so i think this is particularly retarded. i'm sure that some people in my extended family would fall under the 'not brown' category because of their asian appearance (i've got relatives nicknamed "jackie chan" for their resemblance).

as to people looking "not indian," i think the key is can they pass as white. to white people. but honestly, i think white looking indians get more slack than asian looking indians. why else would so many people in bollywood be white indians?

So my overall matches are mostly Irish, English, Swedish and German as might be expected, while my pigmentation skews towards North Eastern Europe.

really strange for a 'black irish' like you :-)

why else would so many people in bollywood be white indians?

Historically Bollywood had many heros/ male leads from Punjab, where people tend to be fair. The early female leads were Parsi/Anglo Indian/Muslim, who all tend to be fair.

That there is a preference for 'Fair' skin cannot be denied, given the huge profits skin creams are making.

one thing that i think is important. SM readers are mostly american. they've probably been the "brown person" their whole life, blah, blah. might have some resentment issues with brownz who can "pass" if they want. i knew a half-brown kid who americanized his first name and easily passed as white. i got a sense his brother who was a touch too tan to pass easily resented him for that (though most of the racism directed at him was because people assumed he was puerto rican).
