**Headline: Genetic Studies Unravel the Complex Ancestry of the Indian Population**

**New Delhi, July 13, 2025** – Groundbreaking genetic research is providing a clearer picture of the origins and evolution of India’s diverse population. A landmark 2009 study, “Reconstructing Indian Population History,” using genetic analysis of 25 groups across India, presented strong evidence for two distinct ancestral populations: the Ancestral North Indians (ANI) and the Ancestral South Indians (ASI).

The study, co-authored by researchers from Harvard, MIT, and CCMB Hyderabad, revealed that ANI are genetically closer to people from West Asia, Central Asia, and Europe, with a higher proportion of ANI ancestry found predominantly in northern India. In contrast, ASI are distinctly different and believed to be of East Eurasian origin. More detailed analysis suggests that ASIs are direct descendants who live in tribal groups in South India. These migrations and the subsequent mixing of populations are believed to have occurred over 3,000-4,000 years ago.

Further research, including a recent paper in Cell, supports the theory that all people of Indian descent can trace their roots back to a single, major migration out of Africa approximately 50,000 years ago.

The genetic studies also shed light on the origins of the Indian caste system. Research indicates a correlation between caste and ancestral components, with “upper” castes often exhibiting a higher proportion of ANI ancestry. However, a 2003 paper pointed out that haplogroup details of various populations across India provide insights into the caste system of India, with certain ancestral components being highest in tribes, somewhat less in lower castes, and least in upper castes.

While the caste system has been a source of discrimination for centuries, with inter-caste marriages historically discouraged, experts say that modern trends are gradually changing this dynamic. Increased access to education, migration for employment, and greater social mobility are leading to a rise in inter-caste and inter-faith marriages. The 2011 Census reported approximately 6% of marriages were inter-caste, and 1% were inter-faith. Observers anticipate a significant increase in these figures when the 2027 Census data becomes available, particularly within urban communities.

This research underscores the intricate and fascinating history of the Indian population, highlighting the interplay between migration, genetic diversity, and social structures.
