Revision summary
* The Andaman and Nicobar Islands are home to four Negrito PVTGs (Great Andamanese, Onge, Jarawa, Sentinelese) and one Mongoloid PVTG (Shompen). * These groups survive on pre-agricultural lifestyles like hunting, gathering, and fishing within tropical rainforest ecosystems. * They suffer from extremely low populations, placing them at perpetual risk of demographic extinction. * Centuries of geographic isolation mean they possess very low physiological immunity to mainland diseases, making epidemics catastrophic. * The 1956 ANPATR regulation provides legal safeguards against territorial intrusion and external exploitation. * State policy has shifted from early assimilation attempts to a current doctrine of "isolation with guarded care." * Long-term survival requires strict territorial buffers, targeted healthcare, and absolute respect for tribal autonomy.

Introduction
The Andaman and Nicobar archipelago hosts several Particularly Vulnerable Tribal Groups (PVTGs) representing distinct Negrito and Mongoloid migrations. These groups, including the Sentinelese, Jarawa, Onge, and Great Andamanese, exhibit high vulnerability due to small populations, pre-agricultural lifestyles, and geographic isolation.
Body
Demographic Profile and Classification
- Tribal Diversity: Comprises four Negrito tribes in the Andaman group (Great Andamanese, Onge, Jarawa, Sentinelese) and two Mongoloid tribes in the Nicobar group (Shompen, Nicobarese, though only Shompen and the Andaman groups are officially classified as PVTGs).
- Population Vulnerability: Most groups suffer from historically low population numbers, ranging from a few individuals for the Sentinelese to a few hundreds for the Onge and Jarawa, placing them at perpetual risk of demographic extinction.
Socio-Cultural and Ecological Adaptation
- Subsistence Strategies: Traditionally dependent on hunting, gathering, fishing, and honey collection, maintaining a sustainable harmony with the tropical rainforest ecosystem.
- Isolation and Immunity: Centuries of geographic isolation have resulted in low physiological immunity against common mainland infectious diseases, rendering epidemics catastrophic.
Protective Policy and Contemporary Challenges
- Legal Safeguards: Protected under the Andaman and Nicobar Islands (Protection of Aboriginal Tribes) Regulation (ANPATR), 1956, which penalises intrusion and exploitation.
- Shift in Approach: Transitioned from historical colonial policies of decimation and subsequent post-independence welfare assimilation to the present doctrine of 'isolation with guarded care' and non-interference.

Conclusion
The PVTGs of the Andaman Islands represent irreplaceable nodes of human biological and cultural diversity. Ensuring their survival necessitates strict enforcement of territorial buffers, empathetic public health interventions, and absolute respect for their autonomy under the constitutional framework.

Evolution of the Indian Culture and Civilization
L. K. Ananthakrishna Iyer is a pioneering figure in Indian anthropology, known for his monumental ethnographic surveys like The Cochin Tribes and Castes and The Mysore Tribes and Castes. Working during the colonial era, he bridged western anthropological methods with indigenous scholarship. His documentation of social stratification, material culture, and folklore laid the empirical foundation for Indian sociology and anthropology. Iyer also established the first department of anthropology in India at the University of Calcutta, shaping institutional teaching and research.

Article 371A of the Indian Constitution.
Evolution of the Indian Culture and Civilization
Article 371A of the Indian Constitution grants special autonomous status to Nagaland, protecting its traditional socio-religious practices, customary laws, and land ownership rights. Enacted via the 13th Constitutional Amendment Act, 1962, following the 16-point Agreement, it reflects the asymmetrical federal framework of India. The article places a special responsibility on the Governor regarding law and order and regional financial allocations. It balances tribal autonomy with national integration, though it faces implementation challenges in modern governance.
