- Proto - Australoids or Austrics
- Mediterranean or Dravidian
- Western Brachycephals
- Nordic Aryans
The Negritos or the Brachycephalic (broad headed) from Africa were the earliest people to have come to India. They have survived in their original habitat in Andaman and Nicobar Islands. The Jarawas, Onges, Sentinelese and the Great Andamanese are some of the examples. Some hill tribes like Irulas, Kodars, Paniyans and Kurumbas are found in some patches in Southern part of mainland India.
Pro-Australoids or Austrics
These groups were the next to come to India after the Negritos. They are people with wavy hair lavishly distributed all over their brown bodies, long headed with low foreheads and prominent eye ridges, noses with low and broad roots, thick jaws, large palates and teeth and small chins. The Austrics of India represent a race of medium height, dark complexion with long heads and rather flat noses but otherwise of regular features. Miscegenation with the earlier Negroids may be the reason for the dark or black pigmentation of the skin and flat noses.
The Austrics laid the foundation of Indian civilization. They cultivated rice and vegetables and made sugar from sugarcane. Now these people are found in some parts of India, Myanmar and the islands of South East Asia. Their languages have survived in the Central and Eastern India.
These people are found in the North eastern part of India in the states of Assam, Nagaland, Mizoram, Meghalaya, Arunachal Pradesh, Manipur, and Tripura. They are also found in Northern parts of West Bengal, Sikkim, and Ladakh. Generally they are people with yellow complexion, oblique eyes, high cheekbones, sparse hair and medium height.
These are the people of South India. They have been believed to come before the Aryans. They have different sub-groups like the Paleo-Mediterranean, the true Mediterranean, and the Oriental Mediterranean. They appear to be people of the same stock as the peoples of Asia Minor and Crete and pre- Hellenic Aegean's of Greece. They are reputed to have built up the city civilization of the Indus valley, whose remains have been found at Mohenjo- daro and Harappa and other Indus cities.
These include the Alpinoids, Dinarics and Armenoids. The Parsis and Kodavas also fall in this category. They are the broad headed people living mainly on the western side of the country such as the Ganga Valley and the delta, parts of Kashmir, Kathiawar, Gujarat, Maharashtra, Karnataka and Tamil Nadu.
Nordics or the Indo-Aryans
This group were the last one to immigrate to India. They came to India somewhere between 2000 and 1500 B.C. They are now mainly found in the northern and central part of India.
