Because of admixture between Caucasoid, Mongoloid and Australoid racial groups, one cannot speak of a biologically separate "Dravidian race" distinct from non-Dravidians on the Indian subcontinent. However, northern Indians have more in common genetically with Central Asian/West Eurasian populations than southern Indian or Dravidian populations, who are more similar to East Asians, further demonstrating that there still exist significant genetic differences between Indo-European- and Dravidian-speaking populations.<ref>http://genome.cshlp.org/content/13/10/2277.short</ref>

Dravidian peoples is a term used to refer to the diverse groups of people who natively speak languages belonging to the Dravidian language family. Populations of speakers of around 220 million are found mostly in Southern India. Other Dravidian people are found in parts of central India, Sri Lanka, Bangladesh, Nepal and Pakistan. The most populous Dravidian people are the Telugus, Tamils, Kannadigas and the Malayalis. Smaller Dravidian communities with 1–5 million speakers are the Tuluvas, Gonds and Brahui.

Etymology

The English word Dravidian was first employed by Robert Caldwell in his book of comparative Dravidian grammar based on the usage of the Sanskrit word drāvida in the work Tantravārttika by Kumārila Bhaṭṭa (Zvelebil 1990:xx). The origin of the Sanskrit word drāviḍa, there have been various theories proposed. These theories are about the direction of derivation between tamiẓ and drāviḍa. Lnguists such as Zvelebil assert that the direction is tamiẓ >drāviḍa (ibid. page xxi).

Origins

Main articles: Proto-Dravidian, Dravidian homeland, Substratum in Vedic Sanskrit, and Elamo-Dravidian languages

Although in modern times speakers of the various Dravidian languages have mainly occupied the southern portion of India, nothing definite is known about the ancient domain of the Dravidian parent speech. It is, however, a well-established and well-supported hypothesis that Dravidian speakers must have been widespread throughout India, including the northwest region.[1] Origins of Dravidian people are informed by various theories proposed by linguists, anthropologists, geneticist and historians. According to geneticist Luigi Luca Cavalli-Sforza in the book The History and Geography of Human Genes, the Dravidians were preceded in the subcontinent by an Austro-Asiatic people, and were followed by Indo-European-speaking migrants sometime later.

Most linguists believe that Dravidian-speaking people were spread throughout the Indian subcontinent before a series of Indo-Aryan migrations. In this view, the early Indus Valley civilization (Harappa and Mohenjo Daro) is often identified as having been Dravidian.[2] Cultural and linguistic similarities have been cited by researchers such as Finnish Indologist Asko Parpola as being strong evidence for a proto-Dravidian origin of the ancient Indus Valley civilization.

Some scholars like J. Bloch and M. Witzel believe that the Indo-Aryan moved into an already Dravidian speaking area after the oldest parts of the Rig Veda were already composed.[3] The Brahui population of Balochistan has been taken by some as the linguistic equivalent of a relict population, perhaps indicating that Dravidian languages were formerly much more widespread and were supplanted by the incoming Indo-Aryan languages.[4]

Thomason & Kaufman (1988) state that there is strong evidence that Dravidian influenced Indic through "shift", that is, native Dravidian speakers learning and adopting Indic languages. Erdosy (1995:18) states that the most plausible explanation for the presence of Dravidian structural features in Old Indo-Aryan is that the majority of early Old Indo-Aryan speakers had a Dravidian mother tongue which they gradually abandoned. Even though the innovative traits in Indic could be explained by multiple internal explanations, early Dravidian influence is the only explanation that can account for all of the innovations at once – it becomes a question of explanatory parsimony; moreover, early Dravidian influence accounts for the several of the innovative traits in Indic better than any internal explanation that has been proposed.[5] Zvelebil remarks[6] that "Several scholars have demonstrated that pre-Indo-Aryan and pre-Dravidian bilingualism in India provided conditions for the far-reaching influence of Dravidian on the Indo-Aryan tongues in the spheres of phonology, syntax and vocabulary".

Genetic anthropology

Main article: Genetics and archaeogenetics of South Asia

Genetic views on race differ in their classification of Dravidians. Classical anthropologists, such as Carleton S. Coon in his 1939 work The Races of Europe, argued that Ethiopia in Northeast Africa and India in South Asia represented the outermost peripheries of the Caucasoid race. In the same vein, the geneticist L.L. Cavalli-Sforza of Stanford, based on work done in the 1980s, classified Indians as being genetically Caucasian. Cavalli-Sforza found that Indians are about three times closer to West Europeans than to East Asians.[7] In the 1960s, genetic anthropologist Stanley Marion Garn considered the entirety of the Indian subcontinent to be a "race" genetically distinct from other populations.[7][8] More recently, other geneticists, such as Lynn B. Jorde and Stephen P. Wooding, demonstrated that South Indians are genetic intermediaries between Europeans and East Asians.[9][10][11] While a number of earlier anthropologists held the view that the Dravidian peoples together were a distinct race, a small number of genetic studies based on uniparental markers have challenged this view. Some researchers have indicated that both Dravidian and Indo-Aryan speakers are indigenous to the Indian subcontinent; however, this point of view is rejected by most researchers in favor of Indo-Aryan migration, with racial stratification among Indian populations being distributed along caste lines.[12][13][14][15] Upper castes of North India have genetically more in common with Central Asian/West Eurasian populations than South Indian upper castes, who are more similar to East Asians.[16]

In a 2009 study of 132 individuals, 560,000 single-nucleotide polymorphisms in 25 different Indian groups were analyzed, providing strong evidence in support of the notion that modern Indians (both Indo-Aryan and Dravidian groups) are a hybrid population descending from two post-Neolithic, genetically divergent populations referred to as the 'Ancestral North Indians' and the 'Ancestral South Indians'. According to the study authors, ASI ancestry is significantly correlated with Dravidian speakers, suggesting that ASI may have been a Dravidian-speaking population before mixing with ancestral ANI groups.[17] Major interminglings of ANI's and ASI's happened 1,200-3,500 years ago, which roughly coincides with the Aryan invasion of the Indian subcontinent.[18]

Language

Main article: Dravidian languages

The best-known Dravidian languages are Tamil (தமிழ்), Telugu (తెలుగు), Kannada (ಕನ್ನಡ) and Malayalam (മലയാളം). There are three subgroups within the Dravidian language family: North Dravidian, Central Dravidian, and South Dravidian, matching for the most part the corresponding regions in the Indian subcontinent.

Dravidian languages are spoken by more than 200 million people. They appear to be unrelated to languages of other known families like Indo-European, specifically Indo-Aryan, which is the other common language family on the Indian subcontinent.

Dravidian grammatical impact on the structure and syntax of Indo-Aryan languages is considered far greater than the Indo-Aryan grammatical impact on Dravidian. Some linguists explain this anomaly by arguing that Middle Indo-Aryan and New Indo-Aryan were built on a Dravidian substratum.[19]

List of Dravidian peoples

  • Bhil: Mostly found in the Tharparkar district of Sindh in Pakistan
  • Bonda: People belonging to the Munda subgroup, mostly found in the isolated hill regions of the Malkangiri district of southwesternmost Orissa, India, near the junction of the three states of Orissa, Chhattisgarh, and Andhra Pradesh.
  • Brahui people: People belonging to the north-Dravidian subgroup, mostly found in the Balochistan province of Pakistan.
  • Gond people: A prominent group of Dravidian-speaking tribal people inhabiting the central region of India.
  • Kannadiga: People belonging to the south-Dravidian subgroup. Mostly found in Karnataka and parts of northern Kerala and parts of southern Maharashtra.
  • Khonds/Kondha: Tribal people who speak the Dravidian Kui language. Mostly found in the eastern Indian states of Orissa and Andhra Pradesh.
  • Kodavas : People belonging to the south-Dravidian subgroup, found in Karnataka and parts of northern Kerala who speak the Kodava language.
  • Kurukh: People belonging to the north-Dravidian subgroup. Found in India and Bangladesh. It is the only Dravidian language indigenous in Bangladesh.
  • Malayali: People belonging to the south-Dravidian subgroup found primarily in Kerala.
  • Tamil: These people belong to south-Dravidian linguistic subgroup. Mostly found in Tamil Nadu, Singapore, Andaman and Nicobar, Sri Lanka, Malaysia and parts of Kerala, Andhra Pradesh, Karnataka and South Africa.
  • Telugus: These people belong to south-Dravidian subgroup (formerly classified with the Central Dravidian but now more specifically in the South Dravidian II or South Central Dravidian inner branch of the South Dravidian (Krishnamurti 2003:p19)). Mostly found in Andhra Pradesh also in Orissa, Tamil Nadu and Karnataka.
  • Tuluvas: People belonging to the south Dravidian subgroup, found in coastal Karnataka and northern Kerala, alternatively named Tulu Nadu.
