Using statistical clustering analysis of radio-carbon dates for Neolithic sites spread from the Near East to South Asia, Gangal et al (1) argue that the Indus Valley civilization came from the Near East. Even though the researchers model the data, they fail to present any archaeological data to support the statistics (1).

Gangal et al (1) claims continuity between the Indus Valley civilization and Mehgarh culture. The researchers failed to recognize that Mehrgarh dates back to 8-6kya in Baluchistan, while the Indus Valley civilization originated 4kya. Granted, Mehrgarh extended to a period of early Harappan, but they represent two distinct cultures.

There is no evidence of cultural continuity between Indian civilizations. The best example is Mehrgarh and the Indus Valley which are separated by 1000's of years. A comparison of the art shows a lack of continuity. Finally, while the people at Mehrgarh and the Near East cultivated Wheat, the Dravidians at Harappa grew Millet (2-3).

The people of the Indus Valley spoke Dravidian languages(4) . This is supported by the fact that Dravidian languages are still spoken in the area; 2) they used the same pottery and writing, and 3) the place names in the Indus Valley are of Dravidian origin (5).

The Dravidians came from Africa (6). They originated in Nubia and belonged to the C-Group people (7-8). The Dravidians used a type of pottery called black-and red ware (BRW) (9).
Archaeologists agree that black and red ware (BRW) unearthed on many

South Indian sites is analogous to Indus valley BRW used by Dravidian-speaking people in South India (10). The BRW style has been found on the lower levels of Madurai and Tirukkampuliyur (10).

B.B. Lal showed that the South Indian BRW was related to Nubian ware dating to the Kerma dynasty(6) . Singh (9) believes that BRW radiated from Nubia through Mesopotamia and Iran southward into India. BRW is found at the lowest levels of Harappa and Lothal dating to 2400 BC (10-11).

The South Indian civilization was created by Dravidian speakers (5, 10-11). Like the people in the Indus Valley they cultivated wheat and possessed the identical writing found on the Indus Valley seals (2-3,11-12).

This is supported by the appearance of Harappan signs on India pottery . Dr. Lal also found that 89% of the graffiti marks on the megalithic red-and-black ware had an affinity to Indus Valley signs (13).

In summary the Indus Valley civilization was founded by Dravidian speaking people who came from Africa (5-6). The Near East populations cultivated wheat. These Harappans of the Indus Valley used black-red pottery, writing and cultivated millets identical to the Dravidian speakers of megalithic India (2-3).
