What Genetics Can, and Cannot, Explain About Caste

A recent WhatsApp exchange between GL and Sbarr captures a recurring Brown Pundits problem: how genetic data, textual tradition, and social history get collapsed into a single argument and then talk past one another. The immediate trigger was a table circulating online, showing ancestry proportions across South Asian groups; Indus Valley–related, Steppe, AASI, and East Asian components. The numbers vary by region and language group. None support purity. None map cleanly onto caste. That much is uncontroversial. What followed was not a dispute about the data itself, but about what kind of claims the data can bear.


GL’s Position (Summarised)

GL’s argument operates at three levels: historical, linguistic, and genetic.

  1. Caste as fluid history

    GL argues that the four-fold varna system hardened late. Terms like Vaishya did not always mean “merchant” but originally derived from viƛ—“the people.” In this reading, Vaishya once referred broadly to non-priestly, non-warrior populations, including farmers and artisans.

  2. Elite religion thesis

    Early Úramaáč‡a movements, Buddhists, Jains, Ajivikas, are framed as elite projects. Renunciation, non-violence, and philosophical inquiry required surplus. Most people, GL argues, worshipped local deities and lived outside these doctrinal systems.

  3. Genes as complexity, not identity

    GL points out that Steppe ancestry and Y-DNA lineages are unevenly distributed. Some peasant groups show higher Steppe ancestry than some Brahmin groups. Maternal lines are largely local. The conclusion is not reclassification, but complication: caste cannot be reverse-engineered from genes. GL’s underlying claim is modest: simple caste narratives do not survive contact with deep history.


Sbarr’s Position (Summarised)

Sbarr’s objections are structural and definitional.

  1. Varna as stable social fact

    In lived Hindu society, Vaishya has meant merchant since at least the Dharmashastra period. Etymology does not override usage. Peasants were not Vaishyas. Shudras worked the land. Dalits lay outside the system.

  2. South Indian specificity

    Sbarr stresses that the North Indian varna model does not transplant cleanly into the Tamil world, where Brahmins, non-Brahmin literati, Jain monks, and Buddhist authors all contributed to classical literature. Claims of universal Brahmin authorship are rejected.

  3. Genes do not make caste

    Even if some peasant or tribal groups show Steppe Y-DNA, this does not make them Brahmins or twice-born. Genetic percentages are low, overlapping, and socially meaningless without institutions.

Sbarr’s core concern is different from GL’s: the danger of dissolving concrete social history into abstract theory.


Where the Debate Breaks Down

The argument falters because the two sides are answering different questions.

  • GL is asking: How did these categories emerge over millennia?

  • Sbarr is asking: How did people actually live, identify, and reproduce hierarchy?

Genes describe populations. Texts describe ideals. Caste describes power. None substitute for the others.


The Takeaway (Without a Verdict)

The ancestry table does not refute caste. The Manusmriti does not explain population genetics. Etymology does not override social practice. What the exchange shows, usefully, is the limit of WhatsApp as a medium for longue-durée history. Complex systems resist compression. When they are forced into slogans, everyone ends up defending a position they did not fully intend. That, more than Steppe percentages or varna theory, is the real lesson here.

Where Do Brahmins Come From?

The Historical, Genetic, and Mythic Answer

The idea that “all Brahmins come from Kannauj” is neat, flattering, and wrong. Kannauj is one important node in a much older, wider story. Brahmins do not descend from a single tribe or city. But they do share ancestry. That ancestry is older than Kannauj, older than caste, and visible in both texts and genes. To understand it, we must keep two truths in view at once: Brahmins have many regional origins, yet they descend—paternally—from a small circle of Vedic founders whose lineages spread across India.

This is the cleanest way to explain it without euphemism or ideology.

1. What the Kannauj Narrative Actually Refers To

When groups claim origin from Kānyakubja (Kannauj), they refer to the medieval centre that produced, housed, and exported Brahmins—especially after the Ghaznavid and Ghurid invasions pushed scribal and priestly families south and west. These migrants seeded communities in Maharashtra, Gujarat, the Konkan, Karnataka, Tamil Nadu, and Andhra. Their prestige shaped memory: “coming from Kannauj” became a shorthand for ritual pedigree. But Kannauj was only one centre among many. It cannot explain the full map of Brahmin origins.

The Aryan Cleft: Pakistan as the Cradle and Cusp of Indo-Iranian Civilisation

The traditional Mercator worldview slices our imagination. It distorts the unity of the Indo-Iranian zone; a civilizational belt that has resisted rupture, even across millennia of empire, religion, and state.

And yet, if you look again, linguistically, genetically, geographically, the facts are harder to ignore. Pakistan sits at the inflection point. Continue reading The Aryan Cleft: Pakistan as the Cradle and Cusp of Indo-Iranian Civilisation
