Odia DNA: Odisha's Ancestry, Castes and Tribes
Few places in India pack as much human history into one state as Odisha. On the coast, in Puri, Cuttack and Bhubaneswar, people speak Odia, an Indo-Aryan language with a literary tradition more than a thousand years old. Travel inland to the hills of Keonjhar, Koraput or Mayurbhanj and you meet Santal, Ho, Juang and Bonda communities who speak Munda languages, a branch of the Austroasiatic family that links India to mainland Southeast Asia. Further south and west live the Kondh and Gond, who speak Dravidian languages related to Telugu and Tamil.
That mix makes Odisha one of the best places in the country to see India's ancestry layers meet. This guide walks through the history of Kalinga, the languages of modern Odisha, and what peer-reviewed genetic studies have actually found in its populations. It also explains, honestly, what a DNA test can and cannot tell an Odia family, including families who identify as Khandayat, Odia Brahmin, Karan, or as members of one of the state's many tribal communities.
The short version: Odisha is where three of India's language families live side by side: Indo-Aryan (Odia), Austroasiatic (Munda languages such as Santali, Ho and Juang) and Dravidian (Kui, Kuvi and Gondi). Genetic studies show that most Indians, Odia speakers included, carry a blend of Ancestral North Indian and Ancestral South Indian ancestry, while Munda speakers also carry roughly a quarter Southeast Asian-related ancestry, mostly arriving through the male line. A DNA test can compare you with reference groups; DNA cannot identify or prove a caste.
Why Odisha is a meeting point of India's ancestry layers
Geneticists describe most of India's population history in terms of a few deep ancestral sources that mixed over thousands of years. In 2009, Reich and colleagues, writing in Nature, analysed 25 diverse Indian groups and showed that most of them descend from a mixture of two ancestral populations they called Ancestral North Indians (ANI), related to people of West Eurasia and Central Asia, and Ancestral South Indians (ASI), a population distinct from both ANI and East Asians. Most Indian groups they studied carried between 39% and 71% ANI-related ancestry.
Later work added detail to that picture. A 2019 study in Science by Narasimhan and colleagues, which analysed 523 ancient individuals, traced South Asian ancestry to a prehistoric gradient between people related to early hunter-gatherers of Iran and of Southeast Asia, with steppe pastoralist ancestry spreading into South Asia from about 4,000 years ago. It also gave a name to the deepest local layer: AASI, the Ancient Ancestral South Indians, an unsampled indigenous population that every Indian group carries in some proportion. Our guide to AASI genetics explains that layer in more depth, and ANI and ASI ancestry explained covers the two-population model.
Odisha matters because a fourth thread runs through it. In 2016, Basu and colleagues, writing in PNAS, analysed 18 mainland Indian populations and two island populations and identified four dominant ancestries on the mainland rather than two. In addition to ANI and ASI, they found two components that are major in specific groups: one they called AAA, "Ancestral Austro-Asiatic", which is prominent in Austroasiatic-speaking tribes such as the Santal, Korwa and Birhor they sampled, and one they called ATB, "Ancestral Tibeto-Burman", prominent in Tibeto-Burman speakers of the northeast. Odisha's Munda-speaking communities speak languages of the same family as the tribes in which Basu found AAA, and they live next door to Odia speakers whose ancestry is usually described on the ANI-ASI spectrum.
From Kalinga to Odisha: a short history that shaped the population
Genes record who married whom over many generations. History explains why. Odisha's history has drawn people in, moved them about and, at times, pushed them into the hills.
Ashoka's war in Kalinga
The ancient kingdom of Kalinga lay along the Bay of Bengal, roughly where coastal Odisha is today. Around 261 BCE, in the eighth year of his reign, the Mauryan emperor Ashoka conquered it. In his own Major Rock Edict XIII, Ashoka records that 150,000 people were deported and 100,000 killed, and he describes the remorse he felt afterwards. Dhauli, near Bhubaneswar, is traditionally identified as the site of the war. No genetic study has yet isolated a signal from the war itself.
Kharavela and the Udayagiri caves
A century or two later, Kalinga rose again under Kharavela, a Jain king of the 2nd or 1st century BCE whose rock-cut Hathigumpha inscription on Udayagiri hill near Bhubaneswar is the main source for his reign. The inscription is undated and only partly legible, and scholars still argue over its details, but it describes military campaigns and public works such as repairs to his capital, Kalinganagara.
The Eastern Gangas, Jagannath and Konark
The medieval Eastern Ganga dynasty left Odisha's two most famous monuments. Anantavarman Chodaganga, the first ruler of that line in Odisha, began the present Jagannath Temple at Puri in the 12th century CE on a site that was already sacred. In the 13th century his successor Narasimha Deva I (who reigned 1238-1264, according to UNESCO) built the Sun Temple at Konark, now a World Heritage Site. Many rituals at Puri preserve elements that scholars link to tribal traditions, a reminder that Odisha's Hindu culture grew up alongside, and partly out of, the cultures of its forest communities.
Odia language and the making of modern Odisha
Odia descends from the eastern Prakrits and passed through Old Odia (10th-13th century) and Middle Odia (14th-17th century) before reaching its modern form. In February 2014 the Government of India declared Odia a classical language, the sixth Indian language to receive that status. Modern Odisha itself is a product of language politics: the Orissa Province was created on 1 April 1936 from the Odia-speaking districts of Bihar and Orissa Province, the Madras Presidency and the Central Provinces, and that date is still celebrated as Utkala Dibasa. The state's name was changed from Orissa to Odisha in 2011.
Odisha's language families, side by side
According to Statement 1 of the 2011 Census language data, 37,521,324 people in India reported Odia as their language, making it one of the larger scheduled languages. Odisha also has the third-largest Scheduled Tribe population of any state: about 9.6 million people in 2011, a little under a quarter of the state's population. The Odisha State Tribal Museum, run by the state's SC and ST Research and Training Institute, lists 62 Scheduled Tribes, 13 of them Particularly Vulnerable Tribal Groups.
The table below sets out the three main language families. Population figures for individual tribes are Scheduled Tribe counts from the 2011 census as published by the Odisha State Tribal Museum; they count people, not speakers, because many tribal families also speak Odia.
| Language family | Languages and communities in Odisha | Speakers or population (2011) | What genetics says |
|---|---|---|---|
| Indo-Aryan (Indo-European) | Odia, spoken by most of the state's caste communities, including Odia Brahmin, Karan and Khandayat families, as well as by many tribal families as a second language | 37,521,324 Odia speakers in India (Census 2011) | Most Indian groups are a blend of ANI and ASI ancestry (Reich 2009), with mixing dated to about 1,900-4,200 years ago (Moorjani 2013). Odia Brahmin and Khandayat are reference groups in our panel. |
| Austroasiatic (Munda branch) | North Munda: Santali, Ho (Kolha), Mundari. South Munda: Juang, Kharia, Sora (Saora), Gutob (Gadaba), Remo (Bonda) | Santal 8,94,764 and Kolha 6,25,009 in Odisha (ST counts); 7,368,192 Santali speakers in India | About a quarter Southeast Asian-related ancestry and high frequencies of Y-DNA haplogroup O2a, with mostly South Asian maternal lineages (Chaubey 2011). Mixing dated to roughly 2,000-3,800 years ago (Tätte 2019). |
| Dravidian | Kui and Kuvi (Kondh, also called Kandha), Gondi (Gond), Kurukh (Oraon) | Kandha 16,27,486 and Gond 8,88,581 in Odisha (ST counts) | Less studied in the genome-wide papers cited here than Munda groups. Gond, Southern Gond and Oraon/Kurukh are reference groups in our panel. |
Language and genes do not map one-to-one. Groups that speak different languages have intermarried, and groups have switched languages over centuries. The table is a guide to where the major ancestral threads are concentrated, not a set of boxes that people fall into.
What genetic studies have found in Odisha's populations
Most genome-wide research involving Odisha has focused on its Austroasiatic-speaking tribes, because they hold the key to an old puzzle: did Austroasiatic languages begin in India and spread east, or begin in Southeast Asia and spread west? Odia-speaking caste communities have been sampled less often in the studies we cite here, so it is worth being clear about which findings apply to whom.
Chaubey and colleagues, 2011: two ancestries in Munda speakers
A 2011 study in Molecular Biology and Evolution by Gyaneshwer Chaubey and colleagues remains one of the most detailed looks at India's Austroasiatic speakers. It combined maternal (mtDNA) and paternal (Y chromosome) markers with about 610,000 genome-wide SNPs, and its samples from Odisha included the Bonda, Savara and Gadaba of Koraput and the Juang. The authors found that Y-DNA haplogroup O2a is common among Indian Austroasiatic speakers and is more diverse, and older, in Southeast Asia, with a coalescent time of 17-28 thousand years ago there. That supported a Southeast Asian origin for the language family.
The genome-wide data told a more complex story. The authors estimated a "notable (23%, standard deviation 5%)" Southeast Asian genetic component among Indian Munda speakers, about a quarter of their ancestry. Roughly two-thirds of Munda Y chromosomes fell into O2a, yet they found no detectable Southeast Asian signal in the mitochondrial DNA of more than 700 Munda samples. Their conclusion: Austroasiatic speakers in India descend from a dispersal from Southeast Asia followed by extensive sex-specific admixture with local Indian populations. In plain terms, incoming men married local women, and the women's lineages, and much of their ancestry, were Indian. Our guide to the O2a haplogroup in India goes deeper into that paternal line.
A competing view: Kumar and colleagues, 2007
Not every study has read the evidence the same way. Earlier, in 2007, Kumar and colleagues analysed Y chromosomes from 1,222 individuals in 25 Indian Austroasiatic populations in BMC Evolutionary Biology. They reported a strong paternal genetic link among Indian Austroasiatic subgroups and with Southeast Asian groups, but they argued that haplogroup O-M95 (part of O2a) arose in Indian Austroasiatic populations and spread from India towards Southeast Asia. The later genome-wide studies favour the Southeast Asian origin, but the existence of this debate is a good reminder that population history is reconstructed from evidence, and interpretations change as data improve.
Tätte and colleagues, 2019: dating the mixture
In 2019, Kai Tätte and colleagues published genome-wide data from 102 Munda speakers in Scientific Reports. They estimated that the Southeast Asian-related and South Asian ancestries in different Munda populations mixed roughly 2,000-3,800 years ago, and that the best modern stand-ins for the two sources were Lao people from Laos and Dravidian speakers from Kerala. They also found that Malaysian Peninsular tribes share more DNA segments with Munda speakers than geographically closer groups such as Vietnamese and Cambodians do, and that the genetic data support the linguists' division of Munda into northern and southern branches. Their South Munda group included the Bonda, Gadaba, Juang, Kharia and Savara.
Basu and colleagues, 2016, and the AAA component
The 2016 PNAS study by Analabha Basu and colleagues, mentioned above, is the one that gave the Austroasiatic thread its own label, AAA. The same paper found that Indian populations once mixed widely, but that this was "rapidly replaced by endogamy about 70 generations ago", mainly among upper castes and Indo-European speakers, with tribal populations showing a similar but less uniform shift. That finding matters for Odisha too: long periods of marriage within communities are why reference groups can be told apart at all.
Narasimhan and colleagues, 2019, and the Juang
The 2019 Science paper by Narasimhan and colleagues singled out an Odisha community. It describes the Juang as "an Austroasiatic-speaking group in India with low West Eurasian-relatedness" and reports that some Austroasiatic-speaking groups, the Juang among them, carry ancestry from a source with more AASI-related ancestry than any group on the main modern Indian cline. The same paper notes that Austroasiatic languages are hypothesised to have spread into South Asia in the 3rd millennium BCE.

Order the Decode KitAASI and the East Asian-related component in Munda speakers
Two components come up again and again when geneticists talk about Odisha, and they are easy to confuse.
AASI: the oldest local layer
AASI is a modelling term for the ancestry of South Asia's earliest hunter-gatherers. No ancient genome from that population has been sequenced, so geneticists infer it from patterns in living people and in ancient samples. In the Narasimhan 2019 model, AASI represents an Asian lineage that split off deep in time, around when the ancestors of East Asians, Andaman Islanders and Australian Aboriginal people separated from one another. All Indian groups carry some AASI-related ancestry. Some tribal communities, including Odisha's Juang, appear to carry more of it than most caste groups do. The Adivasi tribal DNA guide covers how this layer varies across India's tribal communities.
The Southeast Asian-related (East Asian-related) component
The second component is much younger. It is the ancestry that Munda speakers share with Austroasiatic speakers of mainland Southeast Asia, which Chaubey 2011 put at about a quarter and Tätte 2019 dated to roughly 2,000-3,800 years ago. Consumer reports sometimes label it "East Asian" because the reference populations that best match it come from East and Southeast Asia. For an Odia family, any share of this component most likely reflects ancestry from Austroasiatic-speaking communities at some point in the past, although a percentage on its own cannot tell you when or through which ancestor.
Why the father's line and the mother's line disagree
The Munda story is a classic case of sex-biased admixture. The Y chromosome, passed father to son, carries a strong Southeast Asian signal in O2a. Mitochondrial DNA, passed mother to child, is almost entirely South Asian. If you are Odia and your Y-DNA haplogroup turns out to be O2a, it points to a paternal line connected to this Austroasiatic history; if your mtDNA belongs to a South Asian lineage, that matches what Chaubey and colleagues found in the maternal lines of Munda speakers. Neither haplogroup is a community label, and each traces only one line out of thousands of ancestors. Our guide to Bengali DNA covers the same East Asian-related thread in neighbouring Bengal.
Odia castes and DNA: Khandayat, Odia Brahmin and others
Many people searching for "Odia caste DNA" want to know whether a test can confirm family stories. Here the honest answer matters more than anywhere else: DNA cannot identify or prove a caste. Caste is a social category with a long and changing history. What DNA can show is how similar your genome is to reference groups of people who identify with particular communities, and that similarity is a statistical comparison, not membership. Communities are also diverse inside, and none is genetically "purer" or "better" than another. Our explainer Can a DNA test tell your caste? goes through this in detail.
Khandayat
Khandayats are a large Odia-speaking community historically described as a cultivating caste and as a landed militia. In the Khurda kingdom they held tax-free land in return for military service; after the British took Odisha in 1803 and the Paika Rebellion of 1817-1818 failed, they lost most of those lands. Historians also note that caste boundaries were not fixed: during British rule some families from other farming and tribal backgrounds came to identify as Khandayat. That kind of movement is common in Indian social history, and it is one more reason a genetic result can never settle a question of caste identity. Khandayat is one of the two Odisha reference groups in Helixline's panel.
Odia Brahmin
Odia Brahmins, also called Utkala Brahmins, are the priestly communities associated with temples such as Puri. A popular tradition holds that a medieval king, Yayati Keshari, brought Brahmins from Kannauj in the 10th century; that is a legend, but copper-plate land grants do record the settlement of Brahmins in Odisha, such as the Neulpur grant of about 795 CE under the Bhauma-Kara dynasty, which records the settlement of 200 Brahmins. Genetic studies of India generally find more ANI-related ancestry, on average, in traditionally upper-caste and Indo-European speaking groups (Reich 2009), but averages describe populations, not individuals, and any family can sit well away from its group's average. Odia Brahmin is the second Odisha reference group in our panel.
Karan and other Odia communities
Odisha has many other communities, including the Karan (Karana) community, the Chasa and other cultivating castes, artisan and trading groups, Odia Muslims and Christians, and Scheduled Caste communities. These are not yet separate reference groups in our panel. If your family belongs to one of them, your report will still show your overall ancestry composition and how similar you are to the nearest reference groups, which for many Odia families will include Odia, Bengali and eastern Indian groups.
What an Odia family can expect from a Helixline report
Helixline compares your DNA with 7,600+ global reference samples and 140+ South Asian community reference groups. For Odisha, the most relevant groups in our panel are listed below. We only list a group here if it is actually in the panel.
| Reference group in our panel | Listed under | Language family |
|---|---|---|
| Odia Brahmin | Odisha | Indo-European |
| Khandayat | Odisha | Indo-European |
| Santhal Ethnic Group | Jharkhand | Austroasiatic |
| Ho Ethnic Group | Jharkhand | Austroasiatic |
| Munda Ethnic Group | Jharkhand | Austroasiatic |
| Oraon/Kurukh Ethnic Group | Jharkhand | Dravidian |
| Gond and Southern Gond Ethnic Groups | Madhya Pradesh and Andhra Pradesh | Dravidian |
| Bengali Brahmin, Bengali Kayasth, Mahishya and other Bengali groups | West Bengal | Indo-European |
Santal, Ho (Kolha), Munda, Oraon and Gond communities all live in Odisha as well as in neighbouring states, so these reference groups are relevant to Odisha families even though our panel lists them under another state. Some communities that are important to Odisha's story, such as the Juang, Bonda, Kondh and Saora, are not yet separate reference groups.
How to read your results
- Composition, not identity. Your ANI/ASI, steppe and AASI percentages describe a mix of ancient sources. They do not place you in a caste or a tribe.
- Similarity scores are relative. A top match with the Khandayat or Odia Brahmin group means your DNA resembles that reference group more than others in the panel. Neighbouring groups often score close together because they share so much history.
- A small East Asian-related share is normal in eastern India. For Odia families it can reflect Austroasiatic-related ancestry; for families with roots near the northeast it can have other sources. On its own, a percentage does not say which.
- Haplogroups trace one line each. Your Y-DNA (for men) and mtDNA haplogroups follow a single paternal and a single maternal line. They are interesting history, not a community label.
- Test more than one relative. Siblings share about half their DNA, so two siblings can show slightly different results. Testing parents or grandparents from different districts gives a fuller picture.

Frequently Asked Questions
Are Odia people Indo-Aryan or Dravidian?
Odia is an Indo-Aryan language, the eastern branch of the Indo-European family, and about 37.5 million people in India reported it as their language in the 2011 census. Genetics does not follow language neatly, though. Like most Indian groups, Odia speakers carry a mix of ancestry related to Ancestral North Indians and Ancestral South Indians, and Odisha is also home to many Austroasiatic (Munda) and Dravidian speaking tribal communities. The language a family speaks tells you about history and culture; the DNA tells you about a mix of ancestral populations.
Do Munda tribes in Odisha have East Asian ancestry?
Research says yes, partly. A 2011 study in Molecular Biology and Evolution by Chaubey and colleagues, which sampled Bonda, Savara, Gadaba and Juang people from Odisha among other Munda speakers, estimated about a quarter Southeast Asian-related ancestry in Indian Munda speakers. The signal is strongest on the father's line: roughly two-thirds of Munda Y chromosomes fell into haplogroup O2a, while their maternal lineages were almost entirely South Asian. A 2019 study by Tätte and colleagues dated this mixing to roughly 2,000-3,800 years ago.
Can a DNA test tell if I am Khandayat or Odia Brahmin?
No. DNA cannot identify or prove a caste. Caste is a social and historical category, and the boundaries between Odia communities have shifted over centuries. What a test can show is how similar your DNA is to reference groups, such as the Khandayat and Odia Brahmin groups in Helixline's panel. A high similarity score is a statistical comparison, not membership, and it is never a ranking of communities.
What is AASI and why does it matter for Odisha?
AASI stands for Ancient Ancestral South Indian, the name geneticists use for the deep, unsampled indigenous ancestry of South Asia. A 2019 study in Science by Narasimhan and colleagues described it as an Asian lineage that separated very early from other Eurasian lineages, and it singled out the Juang, an Austroasiatic-speaking group of Odisha with low West Eurasian-related ancestry, as carrying ancestry from a source with more AASI-related ancestry than any group on the main Indian cline. Every Indian population carries some AASI; Odisha's tribal communities help geneticists study it.
Which Odisha communities are in Helixline's reference panel?
Helixline's panel of 140+ South Asian community reference groups includes two groups listed under Odisha: Odia Brahmin and Khandayat. It also includes Santhal, Ho and Munda reference groups (listed under Jharkhand, and all three communities also live in Odisha), Gond and Southern Gond groups, the Oraon/Kurukh group and several neighbouring Bengali groups. Some Odisha communities, such as the Juang, Bonda, Kondh and Saora, are not yet separate reference groups.
Can I gift a DNA kit to my parents in Odisha from abroad?
Yes. Kits ship within India as standard, so you can order from abroad at helixline.in/buy, choose Someone in India at checkout, and the kit is delivered to your parents' home with free doorstep pickup of the saliva sample. The Decode kit (₹12,999) adds health, traits and pharmacogenomics reports and a Health Coach consultation to the ancestry report. You can also see the gifting page at helixline.in/gift.
