Is it time for Asian Americans and Latino Americans to ask to be considered “white”? (a)

This is the next article in the series “Is it time for Asian Americans and Latino Americans to ask to be considered “white.” Please also read Razib’s  Hasan Minhaj’s Patriot Act on Affirmative Action.

This panel brought up the issue of affirmative action benefiting caucasians at the expense of people of Asian heritage. According to a 2004 analysis of 1990s data Asians on average needed 140 points more on the SAT (out of 1600) than caucasians all else being equal to have the same probability of admission to elite universities.

Do any readers support race base affirmative action that benefits caucasians at the expense of people of Asian ancestry? If so, can you please share why? I have rarely met Asians who give a strong intellectual case for race based  affirmative action that benefits caucasians at the expense of people of Asian ancestry other than the following arguments:

  • We don’t want to be personally called fascist, nazi, a supporter of the patriarchy, racist, bigoted, prejudiced, imperialist, colonialist, oppressor, hegemonic, exploiter, white supremacist (not joking, Asians are frequently called white supremacist . . . I don’t understand why) etc.
  • We don’t want Asians as a group being called fascist, nazi, supporter of the patriarchy, racist, bigoted, prejudiced, imperialist, colonialist, oppressor, hegemonic, exploiter, white supremacist etc.
  • We want to reduce the “evil eye” or jealousy towards Asians
  • We are guilty because of Asian privilege and Asian oppression of blacks and poor people (never met Asians over 22 who say this, but many K-12 rich Asians children believe this now)
  • This is our punishment because Asians are very fascist, nazi, supportive of the patriarchy, racist, bigoted, prejudiced, imperialist, colonialist, oppressive, hegemonic, exploitative, white supremacist etc. (never met Asians over 22 who say this, but many K-12 rich Asians children believe this now)
  • Xenophobic caucasians might attack us if we don’t support affirmative action.
  • Blacks might attack us if we don’t support affirmative action.

 

In the above discussion Asian Americans seemed afraid to share their actual views. Why are Asian Americans so scared?

To repeat, please share any other reasons you might have for supporting race based affirmative action that discriminates against Asians.

Podcast on South Asian genetics this week

As some of you know I co-host a podcast on genetics and history with Spencer Wells. The very first podcast we recorded in late June of 2017 was about India, but we were still getting the hang of it to be honest, and we didn’t cover much territory.

A lot has happened between then and now, and so it’s time for an “update,” which is going to cover many more topics. That being said, we haven’t recorded yet and so I’m open to “questions from the audience” that we might integrate. So please use this post to leave comments about specific topics…. (please note we have only ~1 hour or so so might not get to everything)

Update: Podcast recorded.

The Munda as upland rice cultivators


I’m reading Ben Keirnan’s Viet Nam: A History from Earliest Times to the Present. I picked it up mostly because over half the book does not consist of the history of the Vietnam War (a major failing I’ve noticed with books which are histories of Vietnam, as opposed to histories of Vietnamese-American relations).

The section on Austro-Asiatic languages (Vietnamese is one) has something of relevance to the “Munda question”. But before that, let me review a few things.

Until very recently many historians and prehistorians of India have suggested that the Munda people, who speak very distinctive dialects related to the Austro-Asiatic languages of Southeast Asia, are the primal people. That is, they are the aboriginals. The original adivasis.

I do not believe that this case is tenable. Because I am a geneticist, I make this judgment on genetic grounds. Chaubey et al., Population Genetic Structure in Indian Austroasiatic Speakers: The Role of Landscape Barriers and Sex-Specific Admixture, reveals what we know about the genome-wide patterns in the Munda.

1) They are highly enriched for East Asian ancestry compared to other South Asians.

2) Many Munda males carry a haplogroup, O-K18 (once O2a), that is very common in Southeast Asia, especially Austro-Asiatic groups. Additionally, it is more diverse in Southeast Asia. The Munda O-K18 branch seems to be a side shoot from the broader Southeast Asian tree.

3) The Munda mtDNA, defining the maternal line, is uniformly South Asian. This is in contrast to the situation with Bengalis, who have East Asia Y and mtDNA. This indicates that the Munda migration was heavily male-mediated.

4) The Munda carry mutations in genes that are associated with recent selective sweeps in East Asians (e.g., on the EDAR locus). Though this may be a parallelism, it’s unlikely. Rather, it is through shared common descent that this occurs.

The Genomic Formation of South and Central Asia has a graph which shows population relationships and gene flow that illustrates important aspects of the Munda ethnogenesis (Juang below):

AASI in this model = Ancient Ancestral South Indians. These are very distantly related to Andaman Islanders, Australo-Melanesian Southeast Asians, and more distantly to eastern Eurasians generally. They are likely aboriginal people to South Asia, with no West Eurasian ancestry.

The model above indicates that an East Asian (Austro-Asiatic) population encountered an AASI population and produced a daughter population. Then, that daughter population mixed with an ASI population, ASI being an old and stable mix of West Eurasian Iranian farmer (~25%) and AASI (75%).

This means two things for the Munda. First, they are very AASI enriched. This is obvious in any analysis. And, their West Eurasian ancestry is almost all Iranian farmer and not steppe. This is totally not surprising either. Using more naive model-based clustering Munda samples always seem to lack the components which are most easily adduced to be Indo-Aryan. They have very low frequencies of Y haplogroup R1a1a-Z93.

Let’s take a step back now. The fact that the Austro-Asiatic males arrived when there were unmixed AASI indicates that this was somewhat early. There are no unmixed AASI on the Indian subcontinent today. When we reach the Iron Age, by 500 BCE it is clear that Indo-Aryan society had pushed at least to Bihar. This component would bring steppe ancestry, as well as mixing into any remnant AASI.

So when could the Austro-Asiatics have arrived at the earliest? Two papers with extensive ancient DNA, Ancient genomes document multiple
waves of migratin in Southeast Asian prehistory
and The prehistoric peopling of Southeast Asia give us a good sense. It seems that the expansion of Austro-Asiatic farmers dates to about 4,000 years ago. That is when the transition seems to occur in northern Vietnam.

One thing that is also evident: the East Asian gene flow into the Munda seems to come from northern Austro-Asiatic groups in Thailand, not the southern branch which resulted in the people of the Nicobar Islands and was eventually submerged by Austronesians. On a final note, a site in northern Burma yielded an individual who was clearly Tibeto-Burman, and not Austro-Asiatic, 3,000 years ago. So even at that date mainland Southeast Asia was heterogeneous.

But, considering that there is no evidence of Tibeto-Burman ancestry Munda, whose Austro-Asiatic ancestry seems to have come through Burma through a mainland route (as opposed to up from maritime Southeast Asia), I think one should push the date of their arrival before 1000 BCE. With the expansion of farming in mainland Southeast Asia at around ~4,000 years ago, that puts the arrival of a distinctive Munda culture in South Asia to between 2000BCE and 1000 BCE. It is entirely reasonable that during this period there were unmixed AASI in eastern South Asia, though the admixture graph may also be picking up assimilation Austro-Melanesian ancestry in southern China/Southeast Asia.

This is where Viet Nam: A History from Earliest Times to the Present comes in: the author suggests that the early Austro-Asiatic farmers were dry-land rice farmers who occupied uplands. The reason being that reconstructed Austro-Asiatic common words for rice culture is indicative of dry-land practices, with later wet-rice terminology often being borrowings from Tai and Austronesians.

I don’t know enough Indian archaeology and agricultural history to comment further, but, a visual inspection of where Munda are concentrated does suggest upland farming….

American Caste (a)

Caucasian Intelligentsia

Some at Brown Pundits have expressed dismay at my using the phrase “caucasian intelligentsia”, maybe because they see this as a criticism of white people. To be clear I am not criticizing people of European ancestry or European influenced culture; but rather a very subtle, pernicious and dangerous colonization of the mind. Some caucasians and non caucasians are at the epicenter of this imperial oppressive hegemonic system. And many good caucasians and non caucasian are fighting against the caucasian intelligentsia. Malcom X and Ali ably describe this caucasian intelligentsia. They call this phenomenon the “white liberal.” Since many caucasian liberals fight against the caucasian intelligentia, I am uncomfortable with the term “white liberal.” I also do not completely agree every aspect of what Malcolm X and Ali say. With that caveat, please listen to the whole thing. the clip is only six minutes long. Some great quotes:

  • “The white liberals [caucasian intelligentsia] from both parties cross party lines to work together toward the same goal”
  • “The white liberal differs from the white conservative in only one way . . . the  liberal [caucasian intelligentsia] is more deceitful, more hypocritical than the conservative”
  • “Both want power but the white liberal [caucasian intelligentsia] is the one who has perfected the art of posing as the negroe’s friend and benefactor and by winning the friendship and support of the negroe the white liberal [caucasian intelligentsia] is able to use the negroe as a pawn or weapon”
  • Ali says that we should love our race and culture

Most but not all of the caucasian intelligentsia comes from post modernism. A sizable minority of the caucasian intelligentsia comes from other caucasian pathologies that can be elaborated on in another post. To massively oversimplify post modernism seeks to negate all metanarratives and universalist norms to observe the world as it truly is. In practice however, modern post modernists see the world through a very narrow incomplete, misleading and biased western ethnocentric filter. In practice they dispute the core of European Enlightenment liberalism and Eastern philosophy, three features of which are:

  • All humans are created equal and endowed with inalienable rights, including the right of life, liberty and pursuit of happiness (eastern philosophy conforms)
  • All humans have the right to freedom of art, speech and thought (eastern philosophy conforms but adds freedom of intuition and feeling)
  • All human beings are potentially powerful, potentially wise and sovereign (eastern philosophy conforms but adds “divine”)

Post modernists disagree with all of these, seeing them as tools of oppression, hegemony, exploitation, colonialism, imperialism, sectarianism, bigotry, prejudice, racism. Post modernists see free expression, liberty or the concept of everyone being potentially wise, powerful and sovereign; as potentially violent and potentially oppressive.

Post modernists are trying to damage the self confidence (Atma Vishwaasa in Sanskrit) of black Americans of African ancestry similar to what they did to former European colonies in Africa and Asia during the 1800s and 1900s. To quote from a previous Brown Pundit post:

Ancient Indian Genetics At ASHG

At ASHG next Monday Niraj Rai will be presenting this poster, Reconstructing the peopling of old world south Asia: From modern to ancient genomes.

South Asia was one of the first geographic regions to be peopled by modern humans after their African exodus. Today, the diverse ethnic groups of South Asia comprise an array of tribes, castes, and religious groups, who are largely endogamous and have hence developed complex, multi-layered genetic differentiation. From such a complex structure, several questions have stood out from the research of our group and others that are only beginning to be resolved using modern sequencing techniques and targeted sampling of populations and archaeological specimens. Here, for the first time we have used ancient genomics approach to understand the deep population ancestry of Indian Sub- continent. Despite the rich sources available of modern Indian populations, success from ancient DNA specimens in the subcontinent have been limited. We have successfully analysed several museum samples and fresh excavation from the different part of India which provides us a wonderful opportunity to be able to relate these modern populations genetically with those in the past and build complex models of population mixture and migration in India. Using ancient genomics data from the human remains who have lived about 4-5 thousand years before present in North West and South of India, we are trying to understand the population history of Iron age people and their genetic relation with the North West of Indians and Iranian Farmers. Furthermore, we are providing a solid Genetic evidence that substantiates archaeological and linguistic evidence for the origins of Dravidian languages and the language of the Indus valley people.

I’ll probably be trying to make sure I catch Rai at the poster. I’m most interested in the South Indian samples. If they date to more than 4,000 years before the present, it will be quite interesting.

Below the fold is my response to a comment on The Roots of Indo-Iranian cultural genesis. My response is in bold. JR’s responses to my original comment are in italics.

Takeaways from the golden age of Indian population genetics

There are lots of strange takes on the India Today piece, 4500-year-old DNA from Rakhigarhi reveals evidence that will unsettle Hindutva nationalists. I’m friendly with the author and saw an early draft. So I’m going to address a few things.

The genetic results are becoming more and more clear. A scaffold is building and becoming very firm. In the 2020s there will be a lot of medical genomics in India. But before that, there will be population genetics. Ancient DNA will be the cherry on the cake.

Here’s what genetics tells us. First, a component of South Asian ancestry, especially in North India, and especially in North Indian upper caste groups, seems to be the same as ancient agro-pastoralists who ranged between modern Ukraine and modern Tajikistan. Genetically, these people are very similar to certain peoples of Central and Eastern Europe of this time, though there is a varied dynamic of uptake of local Central Eurasian elements as they ranged eastward.

This ancestral component is often called “steppe.” This ancestral component is a synthesis of ancient European hunter-gatherer, Siberian, and West Asian. The steppe component seems to arrive in Central and South Asia after 2000 BC.

Second, another component of South Asian ancestry is very distinctive to the region. It is deeply but distantly related to branches of humanity which dominate Melanesia and eastern Eurasia, up into Siberia. The magnitude of the distance probably dates to ~50 thousand years ago, when the dominant element of modern humans expanded outward from West Asia, east, north, and west. These people are called “Ancient Ancestral South Indians,” or AASI. Their closest relatives today may be the natives of the Andaman Islands, but this is a very distant relationship.

AASI is the dominant component of what was once called “Ancestral South Indians,” or ASI. It turns out that “ASI” themselves were a compound synthetic population. This was long suspected by many (e.g., David W.). What was ASI a compound of? About ~75 percent of its ancestry was AASI, but the balance seems to have been a West Eurasian component related to farmers from western Iran. We can call this group “farmers.”

With a few samples from outside of the IVC region, and one (or two) samples from within the IVC region, geneticists are converging upon the likelihood that the profile in the greater IVC region before 2000 BC was a compound of these farmers with the AASI. But even within the IVC region, there seems to have been a range of variation in ancestry. The IVC was a huge zone. It may not have been dominated by a single ethnolinguistic group (even today there is the Burusho linguistic isolate in northern Pakistan). Note that the much smaller Mesopotamian civilization was multiethnic, with a  non-Semitic south and a Semitic north (Sumer and Akkad).

The key point is that it is very likely the IVC lacked the steppe ancestral component. That it did have AASI component. And, it did have a farmer component with likely ultimate provenance in western Iran. Additionally, there were smaller components derived from pre-steppe Central Eurasian people.

While the steppe people arrived in the last 4,000 years, and at least some of the ancestors of the AASI are likely to have been in South Asia for 40,000 years, the presence of the AASI-farmer synthesis genetically is conditional on when a massive presence of western farmers came to affect the northwestern quarter of South Asia. It seems unlikely to have been before Mehrgarh was settled 8,500 years ago. The genetic inferences to estimate the time of admixture between AASI and farmer are currently imprecise, but it seems likely to have begun at least a few thousand years before 2000 BC.  range of 8,500 and 6,000 years ago seems reasonable.

So 4,000 years ago the expanse of the IVC was dominated by a variable mix of farmer and AASI. One can call this “Indus Valley Indian” (IVI).

Just like ASI, there was an earlier abstract construct, “Ancestral North Indian” (ANI). Today it seems that that too was a compound. To be concise, ANI is a synthesis of steppe with IVI. The Kalash of northern Pakistan are very close genetically to ANI. This means that while ASI had West Eurasian ancestry, albeit to a minor extent. And ANI had AASI ancestry, albeit to a minor extent. The main qualitative difference is that ANI had a substantial minority of steppe ancestry.

To a great extent, the algebra of genetic composition across South Asia can be thought of as modulating these three components, farmer, steppe, and AASI.* Consider:

  • Bhumihar people in Bihar tend to have more steppe than typical, but not more farmer than typical, and average amounts of AASI.
  • Sindhi people in Pakistan tend to have lots of farmer, some steppe, and not much AASI.
  • Reddy people in South India have lots of farmer, very little steppe, and average amounts of AASI.
  • Kallar people in South India have some farmer, very little steppe, and lots of AASI.

For details of where I’m getting this, you can look at The Genomic Formation of South and Central Asia for quantities. But as a stylized fact farmer ancestry tends to peak around the Sindh. In Pakistan steppe ancestry increases as you go north. As you go east and south AASI increases pretty steadily, but there are groups further east, such as Jatts and Brahmins, who have a lot of steppe, almost as much as northern Pakistani groups. And curiously you get a pattern where some groups have more steppe and AASI, and less farmer, than is the case to the west (you see this in the Swat valley transect, as steppe & AASI increase in concert).

Going back to the history, by the time the steppe people arrived in South Asia, in the period between 2000 BC and 1000 BC, it may be that the IVI ancestry is what they mixed with predominantly. Though it is likely that the southern and eastern peripheries had “pure” AASI, by the time steppe people spread their culture to these fringes they were already thoroughly mixed with IVI populations, and so already had some AASI ancestry.

In contrast, the farmer populations likely mixed extensively with AASI in situations where the two populations were initially quite distinct.

Please note I have not used the words “Aryan” or “Dravidian.” The reason is that these are modern ethnolinguistic terms. Genetics is arriving at certain truths about population changes and connections, but we don’t have a time machine to go back to the past and determine what language people were speaking 4,000 years ago.

Our inferences rest on supposition, and a shaky synthesis of historical linguistics and archaeology and genetic demography, a synthesis which is unlikely to ever be brought together in one person due to vast chasm of disciplinary method and means.

It is highly likely that the steppe component is associated with Indo-European speaking peoples. Probably Indo-Aryan speaking peoples. The reason is that by historical time, the period after 1000 BC, Iran and Turan seem to already have been dominated by Indo-Iranian peoples. But, in the period around 2000 BC, western Iran was not Indo-Iranian. People like the Guti and the Elamites were not Indo-European, and they were not Semitic. We have some genetic transects which show that steppe ancestry did arrive in parts of Turan and Iran in the period after 2000 BC.

Where did the Dravidian languages come from? We don’t know. They could have been spoken by an AASI group. Or, they could be associated with farmers from the west. We don’t know. Ultimately, we may never know. Unlike Indo-European languages, there are no Dravidian languages outside of South Asia.

Various toponymic evidence indicates that Dravidian languages were spoken at least as far north and west as Gujurat. And Brahui exists today in Balochistan. Though I don’t have strong opinions, I think Dravidian languages probably are descended from a group of extinct languages that were present in Neolithic Iran.

Though unlike Indo-Aryan languages, Dravidian exploded onto the scene after a long period of incubation within South Asia, as part of at least one of the language groups dominant with the IVC and pre-IVC societies.

At least that’s my general assessment. I have strong opinions about the genetics. But am much more curious about what others have to say about linguistics and archaeology.

* Some groups, such as Munda and Indo-Aryan groups in Northeast India, have East Asian ancestry. Some groups in coastal Pakistan have African ancestry.

Genetics stories in India Today

4500-year-old DNA from Rakhigarhi reveals evidence that will unsettle Hindutva nationalists:

The ‘petrous bone’ is an inelegant but useful chunk of the human skull — basically it protects your inner ear. But that’s not all it protects. In recent years, genetic scientists working to extract DNA from ancient skeletons have discovered that, thanks to the extreme density of a particular region of the petrous bone (the bit shielding the cochlea, since you ask), they could sometimes harvest 100 times more DNA from it than from any other remaining tissue.

Now this somewhat macabre innovation may well resolve one of the most heated debates about the history of India.

And, from me, 3 strands of ancestry.

Nothing new for close readers. I would caution

1) Many Hindu nationalists really don’t care and are not perturbed by these findings. I know, because I know them.

2) I don’t know if the paper is going to be published soon. It may, but we’ve been waiting two years now.

On the genetics of Bengal and Southeast Asia

Over at my other weblog, genetics post some readers might have an interest in. I think in the near future I’ll be talking more about the genetics of Southeast Asians and how they were influenced by Indians. Long story short: there’s a significant Indian genetic impact in many areas of Southeast Asia that can’t be ascribed to colonialism. Rather, the spread of Indian culture in the region was probably catalyzed by Indians….

Genetics is not about “dunking” on Hindu nationalists

I need to weigh in real quick about something I’ve been noticing: geneticists don’t do genetics because they are excited about debunking views promoted by some Hindu nationalists and other Indians of a variety of political stripes. In fact, most non-Indian scientists (as in people who don’t live in India) are not totally savvy to the political and social context in South Asia, and so are not aware of how their results may be taken.

Unlike some scientists, I tend to take a dim view of those who assert we need to be careful about how results are going to be interpreted. Science is science. Interpretation is society. Therefore, I don’t particularly care if someone’s cherished views are refuted.

That being said, I have seen on Twitter and elsewhere exultation by anti-Hindu nationalists about new genetic findings, where individuals are wrong in many details of the implications. In the general broad sketch, they understand some implications, but they clearly haven’t paid attention to the science closely, nor do they comprehend it.

There are many examples of confusions and misimpressions. Here is one: the idea that “Vedic civilization” is exogenous to South Asia. I think we need to be very careful about this because I think one can make the case (and this is my position) that by the time most of the archaic mythos of the Indian Aryans crystallized these people were already highly Indianized. To put the political implications on the table, they were much more assimilated in their elite culture than the Muslim rulers of India or the British ever were (and let’s be honest, these are the comparisons people care about).

Rough back-of-the-envelope calculations on my part suggest that ~15% of the total ancestry of all South Asians is steppe derived. That is, about 50% ANI, which is 30% steppe (70% Indus Periphery). Is this a lot? Or not a lot?

Interpretations differ.
