In this episode, Razib Khan explores the historical, cultural, and genetic aspects of the Indian caste system. He discusses the concepts of Varna and Jati, the impact of caste in the Indian subcontinent, its relevance to equity considerations, and its expression among Muslims and Christians. The podcast also touches on comparisons with feudal Japan, the consequences of removed Germanic warriors, and the presence of caste systems in different parts of the world. The genetic variation within the caste system, diversity within the Hindu system, and the potential future decline of the Indian caste system and vegetarianism are also discussed.
The Indian caste system is not limited to Hinduism and extends to Muslims, Christians, and Sikhs as well, with high levels of genetic distance between castes.
Caste is associated with both the varna system, which is a broad categorization used in an academic context, and the jati system, which is a more specific set of social norms and practices where caste identity becomes more pronounced.
The caste system in India has significant levels of genetic variation and stratification, with individuals from different castes being as genetically different as individuals from different continents, indicating historical intermixing and common origins.

The Complexity of the Caste System in India
The caste system in India is a complex social and cultural structure that has been in place for thousands of years. It is not limited to Hinduism, as there are castes among Muslims, Christians, and Sikhs as well. The system is characterized by endogamous marriage practices, with high levels of genetic distance between castes. The four primary ancestral groups in India, including steppe pastoralists, Indus Valley civilization people, Aboriginal hunter-gatherers, and Iranian farmers, have contributed to the genetic makeup of castes. Genetic variation and stratification differ across regions and castes, with higher caste groups generally having more steppe ancestry. However, there are exceptions to this pattern, and caste status is not solely tied to genetic ancestry. It is also influenced by cultural and ritual factors, such as Varna rank and endogamy within castes.
Caste and Ritual Purity
Caste is closely associated with the concept of ritual purity and impurity in Indian society. The varna system, which is associated with the four main ritual ranks of Brahmins, Kshatriyas, Vaishyas, and Shudras, is a broad categorization used in an academic and intellectual context. However, within the Jati system, which is a more detailed and specific set of social norms and practices, caste identity becomes more pronounced. Jati refers to endogamous community groups that have their own rituals, customs, and societal organization. These Jati identities are often more significant to individuals than the overarching Varna identity. The notion of purity and impurity is also important within the caste system. For example, certain castes are traditionally considered 'untouchable' and are believed to transmit pollution. These groups, known as Dalits, are excluded from many social and religious practices and face discrimination in various aspects of life.
Genetic Variation and Stratification
The genetics of the caste system in India reveal significant levels of genetic variation and stratification. Studies have shown that castes in India exhibit high genetic distance from one another, with individuals from different castes often being as genetically different as individuals from different continents. The endogamous marriage practices within castes have led to strong genetic isolation between them, resulting in distinct genetic profiles for each caste. The genetic variations observed between castes are influenced by a combination of factors, including historical population movements, social and cultural practices, and geographic location. Despite genetic variation, there are also shared genetic ancestries between castes, indicating historical intermixing and common origins.
Persistence and Impact of the Caste System
The caste system has persisted for thousands of years in India and continues to have a profound impact on society and individuals. The system affects various aspects of life, including social interactions, marriage, occupation, and access to resources and opportunities. While efforts have been made to address inequalities and discrimination related to caste, the system's influence and effects are deeply ingrained in Indian society. Understanding the complex genetic and cultural dynamics of the caste system is crucial for comprehending the societal dynamics and challenges faced in India.
The Decline of the Caste System in India
The podcast explores the future of the caste system in India, noting that endogamy rates have decreased over time. As urbanization and free market economics increase, the caste system is expected to degrade, becoming more of a cultural artifact. The reservation system, which provides affirmative action for marginalized groups, also plays a role in the various caste dynamics. The complexity of caste classifications and identities can vary by region, making it a fluid and political question. With changing societal dynamics, intermarriage, and a more class-stratified society, the solidities of the caste system are likely to dissolve in the coming generations.
Caste and Power Dynamics in India
The podcast discusses the correlation between caste and power, highlighting that the wealthiest individuals in India are not necessarily Brahmins. Business communities, such as Banias and Jains from Western India, hold great wealth and political influence. While upper castes and land-owning groups may dominate certain regions, there is significant variation across the country. The reservation system, while providing opportunities for marginalized groups, also creates resentment among some upper caste individuals. The changing landscape and rise of backward castes are reshaping the power dynamics in India.

What is caste? This is a question many Americans have been asking since the publication of Isabel Wilkerson’s Caste: The Origins of Our Discontents (an Oprah's Book Club selection). On this episode of Unsupervised Learning, Razib talks at length about the historical, cultural and genetic aspects of caste. He explains the genetic origins and impacts of the practice in the Indian subcontinent, and how that contrasts with “caste” in other societies like feudal Japan. Razib also explores how caste, a European-origin word, came to bracket a sociological phenomenon that includes two related concepts, varna and jati, and how the former is abstract while the latter is concrete.
Caste in the Indian subcontinent has massive social and political implications. Razib talks about the demographics of caste, and how this is relevant to considerations of equity in a nation-state originally founded on socialistic principles. In the subcontinent, caste is not simply a Hindu phenomenon but extends to Muslims and Christians. And in a subcontinent of nearly 2 billion people, caste expresses itself in varied ways depending on region.
Finally, Razib ponders the future of the institution. If diasporic communities like Mauritius and Guyana are any guide, caste has a dim future. With urban jati exogamy rates increasing constantly over the last generation, Razib predicts that in the 22nd century caste in the subcontinent will be viewed as a outmoded practice continued only by a few communities. Caste is a question that is relevant to both the past and the present, but the forces of modernization will eat away at its foundations going forward.
