Which of the following tribes are inhabitants of the Andaman and the Nicobar Islands ? 1. Onge 2. Jarawa 3. Sentinalese Select the correct answer using the codes given below:

1. Racial Classification of Indian Tribes (basic)

To understand the rich tapestry of India’s population, we must look at it through the lens of anthropogeography. India is often described as a "melting pot" or a "museum of races" because, over millennia, different groups of people migrated here in successive waves from Central Asia, China, and Southeast Asia Geography of India, Cultural Setting, p.6. The most authoritative framework for understanding these origins comes from Dr. B.S. Guha, the former Director of the Anthropological Survey of India. Based on physical measurements (anthropometry) taken during the 1931 Census, Guha identified six major racial groups that form the foundation of the Indian population Geography of India, Cultural Setting, p.10.

At the very root of this timeline are the Negritoes, who are widely believed to be the earliest inhabitants of the Indian subcontinent. They are characterized by distinct physical traits: short stature (usually under 150 cm), frizzy or woolly hair, a flat nose, and a dark complexion. While their presence is now limited to small, isolated pockets, they represent a vital link to India's prehistoric past. Their arrival in India is thought to have occurred via the Malay Peninsula, and they share strong cultural and physical affinities with tribes like the Semangs of Malaysia Geography of India, Cultural Setting, p.10.

Geographically, the Negrito element is most preserved in the Andaman Islands and certain hilly tracts of Southern India. In the Andamans, this includes tribes such as the Jarawa, Onge, and Sentinelese. Interestingly, even within a single archipelago, there is racial diversity; while the Andaman group is predominantly Negrito, the Nicobar group (including the Nicobarese and Shompen) belongs to the Mongoloid racial stock, characterized by different features like almond-shaped eyes and straight hair Geography of India, Cultural Setting, p.26.

It is important to remember that these classifications are based on historical and physical data. In the 21st century, due to the expansion of transport networks and social integration, there has been significant intermingling of these groups. As a result, "pure" racial representatives are increasingly rare, and the focus of modern geography is more on the shared cultural identity of these diverse groups Geography of India, Cultural Setting, p.13.

Racial Group	Key Physical Traits	Representative Tribes
Negrito	Short stature, frizzy hair, bulbous forehead	Jarawa, Onge, Sentinelese, Kadar, Irula
Mongoloid	Straight hair, oblique eyes, broad face	Nicobarese, Shompen, various North-East tribes

2. Constitutional Framework for Scheduled Tribes (basic)

In the vast landscape of Indian democracy, the Scheduled Tribes (STs) are recognized not through a rigid definition, but through a unique constitutional process. Interestingly, the Constitution itself does not define who constitutes a 'Scheduled Tribe' D. D. Basu, Minorities, Scheduled Castes and Scheduled Tribes, p.457. Instead, under Article 342, the President has the power to specify these groups in consultation with the Governor of a State. Once this list is notified, any further changes—adding or removing a tribe—can only be made by an Act of Parliament.

To ensure these communities have a voice in governance, the Constitution provides for political reservation proportional to their population. This applies to the Lok Sabha (Article 330), State Legislative Assemblies (Article 332), and even local bodies like Panchayats (Article 243D) D. D. Basu, Panchayats, p.319. In Panchayats, not only are seats reserved for STs, but at least one-third of those reserved seats must be specifically for ST women. These safeguards are designed to bridge the gap between historical isolation and modern democratic participation.

Beyond representation, the Constitution creates a specialized administrative geography to protect tribal land and culture. This is managed through two distinct frameworks under Article 244:

Feature	Fifth Schedule	Sixth Schedule
Applicability	Applies to "Scheduled Areas" in most states across India.	Applies specifically to "Tribal Areas" in Assam, Meghalaya, Tripura, and Mizoram.
Mechanism	Focuses on executive control and Tribal Advisory Councils.	Establishes Autonomous District Councils with legislative and judicial powers D. D. Basu, Administration of Scheduled and Tribal Areas, p.330.

Laxmikanth (7th ed.), Scheduled and Tribal Areas, p.415

3. Particularly Vulnerable Tribal Groups (PVTGs) (intermediate)

In our journey through Indian cultural geography, we must recognize that the term 'Scheduled Tribes' is a broad umbrella. Not all tribal communities are at the same stage of development. In 1973, based on the recommendations of the Dhebar Commission, the government created a sub-category called 'Primitive Tribal Groups' (renamed Particularly Vulnerable Tribal Groups or PVTGs in 2006) to identify those who are most at risk and require specialized protection Indian Polity, M. Laxmikanth, Scheduled and Tribal Areas, p.416. Currently, there are 75 identified PVTGs across 18 states and one Union Territory.

To be classified as a PVTG, a community generally meets four specific criteria:

• A pre-agricultural level of technology (like hunting and gathering).
• A stagnant or declining population.
• Extremely low levels of literacy.
• A subsistence level of economy.

Because these groups are often isolated, they preserve ancient cultural traits and biological lineages that are found nowhere else on Earth.

A prime example of this cultural isolation is found in the Andaman and Nicobar Islands. The archipelago is a microcosm of human migration history, housing tribes from two distinct racial stocks. The tribes of the Andaman group—the Great Andamanese, Onge, Jarawa, and Sentinelese—are of Negrito origin and have maintained a Paleolithic lifestyle for millennia Geography of India, Majid Husain, Cultural Setting, p.26. In contrast, the tribes of the Nicobar group, such as the Shompen, belong to the Mongoloid racial stock.

Racial Stock	Tribal Groups (PVTGs)	Location Focus
Negrito	Jarawa, Onge, Sentinelese, Great Andamanese	Andaman Islands (South/Middle/Little)
Mongoloid	Shompen	Great Nicobar Island

4. Physiography of Andaman and Nicobar Islands (intermediate)

The Andaman and Nicobar Islands represent a magnificent arc-shaped archipelago in the Bay of Bengal, consisting of over 500 islands, islets, and rocks. Geologically, these islands are not merely isolated landmasses but are the elevated peaks of a submerged mountain range. This range is an extension of the Arakan Yoma mountains of Myanmar, which themselves are part of the broader Tertiary fold mountain system that includes the Himalayas Exploring Society: India and Beyond, Landforms and Life, p.45. These islands are situated approximately 2,000 km from the Indian mainland, with the Ten Degree Channel serving as a deep-sea fracture that physically separates the Andaman group in the north from the Nicobar group in the south Geography of India, Physiography, p.66.

The Andaman group is subdivided into North, Middle, South, and Little Andaman. The highest point in this northern cluster is Saddle Peak. In contrast, the Nicobar group includes islands like Car Nicobar, Little Nicobar, and Great Nicobar. The southernmost tip of the entire Indian union, known as Indira Point, is located on Great Nicobar Island Geography of India, Physiography, p.66. While the Andaman islands are predominantly characterized by rugged terrain and dense tropical forests, the Nicobar islands often feature more level land and are home to different ecological and tribal characteristics.

From a cultural geography perspective, this physical separation by the Ten Degree Channel has led to distinct human habitations. The Andaman group is the ancestral home of Negrito tribes (like the Jarawa and Sentinelese), while the Nicobar group is inhabited by tribes of Mongoloid origin (the Nicobarese and Shompen) Geography of India, Cultural Setting, p.26. This distinction highlights how physical barriers in geography often dictate the distribution of human races and cultures.

Feature	Andaman Islands	Nicobar Islands
Racial Stock	Negrito (e.g., Jarawa, Onge)	Mongoloid (e.g., Shompen, Nicobarese)
Highest Peak	Saddle Peak	Mount Thullier (Great Nicobar)
Key Island	Little Andaman	Great Nicobar (Indira Point)

5. Legal Protection: PAT Regulation 1956 (exam-level)

To understand the protection of indigenous communities in the Andaman and Nicobar Islands, we must look at the **Andaman and Nicobar Islands (Protection of Aboriginal Tribes) Regulation, 1956 (PAT)**. This landmark legislation was enacted to create a 'protective shield' around the islands' original inhabitants—specifically the **Jarawa, Sentinelese, Onges, Great Andamanese, Shompen, and Nicobarese**. Given that the tribal population in these islands has been dwindling due to contact with outsiders and diseases, this regulation empowers the administration to declare specific areas as **Tribal Reserves**, where the entry of any person other than the members of the aboriginal tribes is strictly prohibited or regulated via permits Geography of India, Majid Husain, Physiography, p.68.

The PAT Regulation is essential because it respects the distinct racial identities of these groups. In the Andaman group, tribes like the Jarawa and Sentinelese belong to the **Negrito racial stock** and maintain a hunter-gatherer lifestyle, whereas the Nicobar group is home to the **Mongoloid-origin** Shompen and Nicobarese Geography of India, Majid Husain, Cultural Setting, p.26. The law ensures that their land cannot be transferred or sold to non-tribals, thereby preventing the exploitation of their resources. This is further bolstered by the **Island Protection Zone (IPZ) Notification 2011**, which aims to ensure livelihood security for these communities while conserving the islands' thriving biodiversity hotspots Environment, Shankar IAS Academy, Aquatic Ecosystem, p.59.

Enforcement of these protections often falls under the jurisdiction of the **Chief Wildlife Warden**, especially when tribal reserves overlap with National Parks or Sanctuaries. They serve as the authority to control, manage, and maintain these protected areas, ensuring that activities like tourism or scientific research do not infringe upon the sovereignty or health of isolated groups like the Sentinelese Environment, Shankar IAS Academy, Protected Area Network, p.214. This legal framework is what allows the Sentinelese to remain the most isolated group in the world, maintaining a Paleolithic lifestyle free from external interference.

6. Major Tribes of the A&N Archipelago (exam-level)

The Andaman and Nicobar Islands represent one of the most unique anthropological zones in the world. To understand their cultural geography, we must first divide the archipelago into two distinct clusters: the Andaman group in the north and the Nicobar group in the south, separated by the 10-degree channel. This geographical split corresponds to a significant racial and cultural divide between the indigenous inhabitants.

In the Andaman group, the indigenous tribes belong to the Negrito racial stock. These groups are characterized by their hunter-gatherer lifestyle and have remained relatively isolated for thousands of years. The four major tribes here are the Great Andamanese, the Onge (who primarily inhabit Little Andaman), the Jarawa (residing in South and Middle Andaman), and the Sentinelese. The Sentinelese are famously the most isolated, inhabiting North Sentinel Island and maintaining a Paleolithic lifestyle while fiercely resisting outside contact Geography of India, Regional Development and Planning, p.90. The Jarawa, also known as Angs, are currently considered one of the most endangered tribes globally, though their population has shown a slight recovery in recent years Geography of India, Cultural Setting, p.26.

In contrast, the Nicobar group is home to tribes of Mongoloid origin. These include the Nicobarese and the Shompen. While the Nicobarese have integrated more with the modern economy—often engaging in the trade of coconut and arecanut—the Shompen remain semi-nomadic and live in the interior of the Great Nicobar Island Geography of India, Physiography, p.68. It is important to note that while these indigenous cultures are the historical soul of the islands, they are now a minority; the majority of the current population consists of migrants from mainland India, Bangladesh, and Myanmar Geography of India, Physiography, p.68.

Feature	Andaman Group Tribes	Nicobar Group Tribes
Racial Stock	Negrito	Mongoloid
Major Groups	Jarawa, Onge, Sentinelese, Great Andamanese	Nicobarese, Shompen
Contact Status	Highly isolated to semi-isolated	Relatively integrated (Nicobarese)

7. Solving the Original PYQ (exam-level)

Now that you have mastered the ethnographic distribution of India, you can see how the distinction between the Negrito and Mongoloid racial groups is the critical building block for this question. This PYQ tests your ability to precisely categorize the Particularly Vulnerable Tribal Groups (PVTGs) of the Andaman and Nicobar Islands. As you learned in the conceptual modules, the Andaman group is historically home to the Negrito tribes—specifically the Great Andamanese, Jarawa, Onge, and Sentinelese—while the Nicobar group is inhabited by those of Mongoloid descent, such as the Nicobarese and Shompen.

To arrive at the correct answer (D), use a geographic walkthrough: the Onge are primarily settled on Little Andaman, the Jarawa inhabit the South and Middle Andaman, and the Sentinelese remain the world's most isolated group on North Sentinel Island. Since all three listed groups belong to the Andaman division of the archipelago, they are all correctly identified as inhabitants of the islands. The logical bridge here is recognizing that 'Andaman and Nicobar' is treated as a single administrative and geographical unit in the question, even though the tribes are localized to specific islands within that chain.

UPSC frequently uses Options (A), (B), and (C) as traps to see if you will second-guess the status of the Sentinelese due to their lack of contact or the Onge due to their small population size. A common distractor in similar questions is the inclusion of the Shompen or a mainland tribe like the Toda; if those were present, you would need to eliminate them to find the specific Andaman-centric list. By referring to Geography of India by Majid Husain, we confirm that these three, along with the Great Andamanese, form the core indigenous identity of the Andaman region, making the all-of-the-above choice the only accurate synthesis.
