On 22 June 2026, the Archaeological Survey of India (ASI) formally handed over human skeletal remains excavated at Rakhigarhi in Haryana to the Anthropological Survey of India (AnSI), a research body under the Ministry of Culture, for detailed scientific study. Under a freshly signed MoU between the two institutions, three complete skeletons (plus fragments) recovered in the 2025–26 field season from Mound No. 7 — a cemetery zone — were moved to AnSI's ancient-human-skeletal repository and laboratory in Kolkata. There they will undergo ancient-DNA (aDNA) analysis, stable-isotope studies, osteology and palaeopathology, in collaboration with the Birbal Sahni Institute of Palaeosciences (Lucknow), University College London and a Banaras Hindu University aDNA team.
For an NDA/CDS aspirant the news itself is small, but the doorway it opens is enormous: Rakhigarhi is one of the largest sites of the Indus Valley (Harappan) Civilisation, the IVC is a guaranteed slice of the General Studies history syllabus, and the aDNA angle touches the much-discussed Aryan-migration debate. This is exactly the kind of release where the smart move is to learn the whole topic cluster behind the headline — and that is what we will do.
What Rakhigarhi is, and why it matters
Rakhigarhi sits in the Hisar district of Haryana, on the now-dry bed of the ancient Saraswati–Drishadvati river system, about 150 km northwest of Delhi. It is widely recognised as the largest Harappan settlement in the Indian subcontinent — the PIB release puts its spread at roughly 550 hectares, and even the more conservative commonly-cited figure of about 350 hectares makes it larger than Mohenjo-daro. The site is a cluster of mounds (often counted as eleven), showing continuous habitation from the Early Harappan through the Mature Harappan phases, with planned streets, a drainage system, craft-production areas, trade networks and burial grounds.
What makes Rakhigarhi a current-affairs favourite is the 2018–2019 ancient-DNA study of a skeleton from the site. The aDNA recovered showed no trace of the "Steppe" (Central Asian) genetic ancestry associated with later Indo-European/Aryan migrations — a finding that fed directly into the long-running scholarly debate on the origins of the Harappans and the Aryan question. The 2026 transfer of fresh skeletons to AnSI is a continuation of that scientific project: more genomes mean a sharper picture of ancestry, migration, diet and disease in the Indus population. If you track our daily NDA current affairs, you will see history-and-science crossovers like this appear again and again.
The Indus Valley Civilisation: the essentials
The Indus Valley Civilisation (IVC), also called the Harappan Civilisation after its first-excavated site, was one of the world's three earliest urban civilisations (alongside Mesopotamia and Egypt). Fix this chronology, because dates are the most-asked element:
- Early Harappan phase: c. 3300–2600 BCE
- Mature (urban) phase: c. 2600–1900 BCE — the peak, with the great cities
- Late Harappan / decline: c. 1900–1300 BCE
It is named Harappan because Harappa (on the Ravi, now in Pakistan's Punjab) was the first site excavated, in 1921 by Daya Ram Sahni under the ASI. Mohenjo-daro (on the Indus, in Sindh) was excavated in 1922 by R.D. Banerji. The civilisation was an urban, Bronze Age culture: it knew bronze, but not iron.
The defining achievement was town planning. Remember the standard package:
- A grid layout of streets crossing at right angles, dividing the city into blocks.
- A two-part plan: a raised, fortified Citadel to the west (public/administrative buildings) and a lower residential town to the east.
- An advanced covered drainage system running along the streets — the single most-quoted marvel of Harappan engineering.
- Standardised, kiln-fired bricks in a fixed ratio (typically 4:2:1), used across sites hundreds of kilometres apart — evidence of a shared culture and standard weights and measures.
- The Great Bath at Mohenjo-daro — a large watertight tank, probably for ritual bathing — and large granaries for grain storage.
The Harappans had a script, written mostly on seals, but it remains undeciphered to this day and is generally read right to left. The economy rested on agriculture, craft and trade, including long-distance trade with Mesopotamia (where the Harappans were called "Meluha"). The famous artefacts — the bronze "Dancing Girl", the steatite "Priest-King" bust, and the "Pashupati" seal showing a horned figure — all come from this milieu.
Major sites, their rivers and their modern locations
NDA loves "match the site to its river / state / feature." This table is worth memorising cold:
- Harappa — river Ravi — Punjab, Pakistan. First excavated (1921); granaries, cemeteries (R-37).
- Mohenjo-daro ("Mound of the Dead") — river Indus — Sindh, Pakistan. The Great Bath, the Great Granary, the Priest-King and Dancing Girl.
- Rakhigarhi — Saraswati/Drishadvati belt — Haryana, India. Largest site in the subcontinent; the aDNA work.
- Dholavira — in the Rann of Kutch, Gujarat, India. Famous for water-conservation reservoirs, a unique three-part city plan, and a signboard of Harappan script; a UNESCO World Heritage Site (2021).
- Lothal — Gujarat, India (Bhogavo/Sabarmati area). A dockyard — a port for maritime trade — plus a bead-making industry.
- Kalibangan — river Ghaggar — Rajasthan, India. Evidence of a ploughed field and fire altars.
- Banawali — Haryana, India. Both Early and Mature Harappan layers.
- Chanhudaro — Sindh, Pakistan. A bead-and-craft manufacturing town (no citadel).
- Surkotada — Gujarat, India. Disputed evidence of horse remains.
A clean revision shortcut: the famous "P" sites (Harappa, Mohenjo-daro, Chanhudaro) are in Pakistan; the showcase Indian sites (Rakhigarhi, Dholavira, Lothal, Kalibangan, Banawali, Surkotada) cluster in Haryana, Gujarat and Rajasthan along the Saraswati–Ghaggar system. The civilisation as a whole stretched from Sutkagendor (near the Iran border in the west) to Alamgirpur (Uttar Pradesh, east), and from Manda (Jammu, north) to Daimabad (Maharashtra, south) — making it the largest in area of the early civilisations.
The Aryan-migration / aDNA debate, kept factual
This is a sensitive but examinable area, so handle it at the level of established fact, not opinion. Two old positions framed the debate: an "Aryan invasion/migration" view (Indo-European-speaking pastoralists entered the subcontinent from the Central Asian Steppe in the second millennium BCE, after the IVC's mature phase) and an "indigenous/Out-of-India" view (the Vedic culture was native).
Modern ancient-DNA science has reframed the question. The headline findings most cited in current affairs:
- The Rakhigarhi genome lacked detectable Steppe ancestry, suggesting the mature Harappans themselves were a mix of local South-Asian hunter-gatherer ancestry and an Iranian-related (agricultural) component, without the Steppe element.
- Broader studies of the region (the so-called "Indus Periphery" samples) indicate that Steppe-related ancestry arrived later, after roughly 2000–1500 BCE, consistent with gene flow (migration), not a single violent invasion.
The exam-safe takeaway is simply this: aDNA shows the Indus population predates the Steppe genetic input, and that input came later as migration — which is why fresh Rakhigarhi skeletons going to AnSI for genome study is treated as scientifically important. You do not need to take sides; you need to know what the data shows. This kind of factual, source-based reasoning is exactly what we train at The Cavalier.
AnSI vs ASI: don't confuse the two
The release hinges on a handover between two bodies whose names look alike but whose work is different — a classic trap:
- ASI — Archaeological Survey of India. Founded 1861 (under Alexander Cunningham), now under the Ministry of Culture, HQ New Delhi. It excavates, conserves and protects monuments and archaeological sites — it digs up the past (it ran the Rakhigarhi excavation).
- AnSI — Anthropological Survey of India. Established 1945, HQ Kolkata, also under the Ministry of Culture. It is the premier body for anthropological research — the study of human beings: their biology (osteology, genetics), society and culture. It studies the people (it received the skeletons).
So the logic of the news is tidy: ASI dug up the bones; AnSI will study the bones. AnSI is one of a family of "Survey" institutions you should be able to list — alongside the Geological Survey of India (GSI), Botanical Survey of India (BSI) and Zoological Survey of India (ZSI) — several of which AnSI plans to partner with on the palaeoclimate angle. The "scientific institutions" mentioned in the release — CCMB Hyderabad (genetics), BSIP Lucknow (palaeosciences) — are themselves frequent GK names. For a deeper consolidation of bodies, dates and sites like these, our NDA general knowledge study material is built around exactly this kind of fact-mapping.

📋 How this gets asked (PYQ pattern)
The Indus Valley Civilisation is one of the most reliably-tested chunks of NDA/CDS ancient history. Past papers favour a few stable patterns: match-the-site items (site → river → modern state → signature feature: Mohenjo-daro/Great Bath, Lothal/dockyard, Kalibangan/ploughed field, Dholavira/reservoirs); chronology (the c. 2600–1900 BCE mature phase); "first excavated" and excavator trivia (Harappa, 1921, Daya Ram Sahni); the undeciphered script; and the standard town-planning marvels (grid streets, covered drains, standardised bricks, the citadel-and-lower-town split). Statement-based "which of the following is/are correct" questions on IVC features are common, so precision matters. The fresh 2026 hook is twofold: Rakhigarhi as the largest site + the aDNA/Aryan-migration angle, and the ASI-versus-AnSI institutional distinction (who digs vs who studies people; AnSI's 1945/Kolkata/Ministry-of-Culture profile). Expect either a direct "Rakhigarhi is in which state?" item or a body-identification question pairing AnSI with its parent ministry.
