The '''Onge''' (also '''Önge''', '''Ongee''', and '''Öñge''') are an [[Andamanese peoples|Andamanese ethnic group]], indigenous to the [[Andaman Islands]] in [[Southeast Asia]] at the [[Bay of Bengal]], currently administered by [[India]]. They are traditionally [[hunter-gatherers|hunter-gatherers and fishers]], but also practice [[plant cultivation]]. They are designated as a [[Scheduled Castes and Scheduled Tribes|Scheduled Tribe]] of India.<ref>{{cite web |url=http://censusindia.gov.in/Tables_Published/SCST/ST%20Lists.pdf |page=27 |title=List of notified Scheduled Tribes |publisher=Census India |access-date=15 December 2013 |archive-url=https://web.archive.org/web/20131107225208/http://censusindia.gov.in/Tables_Published/SCST/ST%20Lists.pdf |archive-date=7 November 2013 |url-status=dead }}</ref>
 
== History ==
[[File:Andamanese comparative distribution.png|thumb|left|200px|Distribution of Andamanese tribes in early 1800s and 2004; the Onge areas are in blue.]]
In the 18th century the Onge, or Madhumitha, were distributed across [[Little Andaman Island]] and the nearby islands, with some territory and camps established on [[Rutland Island]] and the southern tip of [[South Andaman Island]]. After they encountered British colonial officers, friendly relations were established with the [[British Empire]] in the 1800s through Lieutenant [[Archibald Blair]]. British naval officer [[Maurice Vidal Portman|M. V. Portman]] described them as the "mildest, most timid, and inoffensive" group of Andamanese people he had encountered.<ref name="weber">{{cite web|first=George|last=Weber|url=http://www.andaman.org/BOOK/app-a/a-portman.htm|title=Maurice Vidal Portman (1861–1935)|work=The Andamanese (Appendix A – Pioneer Biographies of the British Period to 1947)|access-date=2012-07-03|archive-url=https://web.archive.org/web/20120805204050/http://www.andaman.org/BOOK/app-a/a-portman.htm|archive-date=5 August 2012|url-status=dead|df=dmy-all}}</ref><ref name="portman"/> By the end of the 19th century they sometimes visited the [[South Brother Island, India|South]] and [[North Brother Island, India|North Brother Islands]] to catch [[sea turtle]]s; at the time, those islands seemed to be the boundary between their territory and the range of the [[Great Andamanese people]] further north.<ref name="portman">M.

A major cause of the decline in Onge population is the changes in their food habits brought about by their contact with the outside world.<ref>Devi, L. Dilly (1987).

=== Tsunami surviving tactics ===
The semi-nomadic Onge have traditional stories that tellstell of the ground shaking and a great wall of water destroying the land. Taking heed of this story, the Onge survived the [[tsunami|tsunami catastrophe]] caused by the [[2004 Indian Ocean earthquake]] by taking shelter in the highlands.<ref>{{cite web |url=http://www.culturalsurvival.org/publications/cultural-survival-quarterly/mariana-budjeryn/and-then-came-tsunami-disaster-brings-atte |title=And Then Came the Tsunami: Disaster Brings Attention and New Challenges to Asia's Indigenous Peoples |access-date=22 February 2010 |last=Budjeryn |first=Mariana |publisher=[[Cultural Survival Quarterly]]}}</ref>
 
=== Poisoning incident ===
In December 2008, eight male tribal members died after drinking a toxic liquid{{spnd}}identified as [[methanol]] by some sources{{spnd}}that they had apparently mistaken for [[ethanol|drinking alcohol]].<ref name="alcerr">{{cite news|last=Bhaumik|first=Subir|date=9 December 2008|title=Alcohol error hits Andamans tribe|work=[[BBC News]]|url=http://news.bbc.co.uk/2/hi/south_asia/7772952.stm|access-date=10 December 2008}}</ref> The liquid apparently came from a container that had washed ashore at Dugong Creek near their settlement on the island, but Port Blair authorities ordered an investigation into whether it had originated elsewhere. A further 15 Onge were taken to hospital with at least one critically ill.<ref name="bottle">{{cite web|author=Buncombe, Andrew|date=12 December 2008|title=Washed-up poison bottle kills eight members of island tribe|url=https://www.independent.co.uk/news/world/asia/washedup-poison-bottle-kills-eight-members-of-island-tribe-1062908.html|url-status=dead|archive-url=https://web.archive.org/web/20081212223232/http://www.independent.co.uk/news/world/asia/washedup-poison-bottle-kills-eight-members-of-island-tribe-1062908.html|archive-date=12 December 2008|access-date=12 December 2008|location=London|format=online edition|newspaper=[[The Independent]]}}</ref>
 
With their population estimated at only around 100 before the incident, the director of [[Survival International]] described the mass poisoning as a "calamity for the Onge", and warned that any more deaths could "put the survival of the entire tribe in serious danger".<ref name="bottle" /> [[Bhopinder Singh]], the [[List of lieutenant governors of the Andaman and Nicobar Islands|Lieutenant Governor of the Andaman Islands]], ordered an inquiry into the incident.<ref>{{cite web|date=11 December 2008|title=Inquiry ordered into death of Onge tribesmen|url=http://www.hindu.com/thehindu/holnus/001200812111313.htm|url-status=dead|archive-url=https://web.archive.org/web/20121103151921/http://www.hindu.com/thehindu/holnus/001200812111313.htm|archive-date=3 November 2012|access-date=13 December 2008|work=[[The Hindu]]|df=dmy-all}}</ref> The Onge have been rather vulnerable toward any option for radical change, they deserve close, careful attention to ward off any untoward impact of change-initiatives.<ref>{{Cite book |last=Danda |first=Dipali |last2=Mukherjee |first2=Sumit |title=Dilemma of Development among the Onge of Andaman |date=2021 |publisher=Taylor & Francis |isbn=9781032151274}}</ref>
 
== Culture and religion ==
The native Andamanese religion and belief system is a form of [[Animismanimism]]. [[Ancestor worship]] is an important element in the religious traditions of the Andaman islands.<ref>{{cite journal|vauthors=Bxown AK|date=30 September 1909|title=The Religion of the Andaman Islanders|journal=Folklore|volume=20|issue=3|pages=257–371|doi=10.1080/0015587X.1909.9719883}}</ref> The Andamanese probably had no government or clan leader, but made decisions by group [[Consensus decision-making|consensus]].<ref>{{Cite book|title=The Andaman Islanders|vauthors=Brown AR|publisher=Cambridge University Press|year=1933|location=Cambridge|pages=44}}</ref>
 
== Language ==
The Onge speak the [[Önge language]]. It is one of two known [[Ongan languages]] (southern [[Andamanese languages]]). Önge used to be spoken throughout Little Andaman as well as in smaller islands to the north, and possibly in the southern tip of [[South Andaman]] island. Since the middle of the 19th century, with the arrival of the British in the [[Andaman Islands|Andamans]], and, after [[Partition of India|Indian independence]], the massive inflow of Indian settlers from the mainland, the number of Onge speakers has steadily declined. However, a moderate increase has been observed in recent years.<ref>{{cite web |url=http://www.combatlaw.org/information.php?article_id=23&issue_id=9 |title=The Colonisation of Little Andaman Island |access-date=23 June 2008 }}{{dead link|date=January 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> {{As of|2006}}, there were 94 native Onge speakers<ref name="Ethnologue">{{cite book |editor1-first=M.&nbsp;Paul |editor1-last=Lewis |editor2-first=Gary&nbsp;F. |editor2-last=Simons |editor3-first=Charles&nbsp;D. |editor3-last=Fennig |year=2013 |title=Ethnologue: Languages of the World |chapter=Öñge |edition=17th |location=Dallas, Texas |publisher=SIL International |chapter-url=http://www.ethnologue.com/17/language/oon |archive-url=https://web.archive.org/web/20160309160836/http://www.ethnologue.com/17/language/oon/ |archive-date=9 March 2016 |url-status=live |df=dmy-all }}</ref> confined to a single settlement in the northeast of Little Andaman Island (see map above), making it an [[endangered language]].
 
The [[Ongan languages]], to which Onge belongs, have been proposed by [[Juliette Blevins]] to be related to [[East Asian languages|Mainland Asian languages]], such as [[Austronesian languages|Austronesian]].<ref>Blevins, Juliette (2007), "A Long Lost Sister of Proto-Austronesian? Proto-Ongan, Mother of Jarawa and Onge of the Andaman Islands" (PDF), ''Oceanic Linguistics'', '''46''' (1): 154–198, [[Doi (identifier)|doi]]:10.1353/ol.2007.0015, [[S2CID (identifier)|S2CID]] 143141296</ref> However, this proposal has not been well received by other linguists, such as [[Robert Blust]], who concludes that the hypothesis is not supported by the [[comparative method]] (used in linguistics), and also cites non-linguistic (such as cultural, archaeological, and biological) evidence against Blevins' hypothesis.<ref>Blust, Robert (2014). "Some Recent Proposals Concerning the Classification of the Austronesian Languages", ''Oceanic Linguistics'' 53:2:300&ndash;391. "To put it bluntly, the AON hypothesis is a castle built on sand, an elaborate illusion fostered by the misplaced hope that a major discovery has been made that somehow eluded the investigations of all other scholars."|url=https://www.researchgate.net/publication/279031484_Some_Recent_Proposals_Concerning_the_Classification_of_the_Austronesian_Languages</ref> and [[George van Driem]] (2011), who considers Blevins' evidence as "not compelling", although he leaves the possibility open that some resemblances could be the result of contact/borrowing, a position also held by Hoogervorst (2012).<ref>{{cite book |last=van Driem |first=George |year=2011 |chapter=Rice and the Austroasiatic and Hmong-Mien homelands |chapter-url=https://www.researchgate.net/publication/256442016 |accessdate= 13 November 2021 |editor=N.J Enfield |title=Dynamics of human diversity: the case of mainland Southeast Asia |location=Canberra |publisher=Pacific Linguistics}}</ref><ref>{{cite thesis |last=Hoogervorst |first=Tom |year=2012 |title=Southeast Asia in the ancient Indian Ocean world: combining historical linguistic and archaeological approaches |type=PhD thesis |publisher=University of Oxford |url=https://ora.ox.ac.uk/objects/uuid:b8b47816-7184-42ab-958e-026bc3431ea3 |accessdate=13 November 2021 |quote=Nevertheless, it is conceivable that some of the given forms are genuinely related, though better explained as loans than common inheritance (p. 91).}}</ref>

Genetically, the Onge, as well as other Andamanese people, are distantly related to [[East Asian people]]. The Andamanese Onge show the highest affinity towards some Southeast Asian [[Negrito]] ethnic groups, such as the [[Aeta people]], but also ancient remains of [[Hoabinhian]]s, which are all characterized by Basal-East Asian ancestry. It was found that Andamanese (Onge) split from the common ancestor of modern day East Asians between 50,000BC000&nbsp;BC toand 25,000BC000&nbsp;BC, before becoming isolated on the [[Andaman Islands]]. The Andamanese (Onge) as well as East Asians, are also distantly related to the Indigenous population of [[South Asia]]. Recent genetic evidence suggest that a Basal-East Asian population (close or ancestral to Andamanese and East Asians) was widespread in [[Asia]] and contributed to the formation of modern South Asians ([[Indian people]]).<ref>{{Cite journal|last1=Carlhoff|first1=Selina|last2=Duli|first2=Akin|last3=Nägele|first3=Kathrin|last4=Nur|first4=Muhammad|last5=Skov|first5=Laurits|last6=Sumantri|first6=Iwan|last7=Oktaviana|first7=Adhi Agus|last8=Hakim|first8=Budianto|last9=Burhan|first9=Basran|last10=Syahdar|first10=Fardi Ali|last11=McGahan|first11=David P.|date=2021|title=Genome of a middle Holocene hunter-gatherer from Wallacea|journal=Nature|volume=596|issue=7873|pages=543–547|doi=10.1038/s41586-021-03823-6|issn=0028-0836|pmc=8387238|pmid=34433944|bibcode=2021Natur.596..543C}}</ref><ref>{{Cite journal|last1=Larena|first1=Maximilian|last2=Sanchez-Quinto|first2=Federico|last3=Sjödin|first3=Per|last4=McKenna|first4=James|last5=Ebeo|first5=Carlo|last6=Reyes|first6=Rebecca|last7=Casel|first7=Ophelia|last8=Huang|first8=Jin-Yuan|last9=Hagada|first9=Kim Pullupul|last10=Guilay|first10=Dennis|last11=Reyes|first11=Jennelyn|date=2021-03-30|title=Multiple migrations to the Philippines during the last 50,000 years|journal=Proceedings of the National Academy of Sciences of the United States of America|volume=118|issue=13|pages=e2026132118|doi=10.1073/pnas.2026132118|issn=0027-8424|pmc=8020671|pmid=33753512|bibcode=2021PNAS..11826132L |doi-access=free }}</ref><ref name="LipsonReich2017">{{cite journal|last1=Lipson|first1=Mark|last2=Reich|first2=David|year=2017|title=working model of the deep relationships of diverse modern human genetic lineages outside of Africa|url= |journal=Molecular Biology and Evolution|volume=34|issue=4|pages=889–902|doi=10.1093/molbev/msw293|pmid=28074030|issn=0737-4038|pmc=5400393}}</ref>

A study by Reich et al. (2009) found that while the Onge are distantly related to modern Indian people, they have none of the admixture from [[Neolithic]] Iranian farmers or [[Yamnaya culture|steppe pastoralists]] which is widespread on the mainland.
