“The Indus Valley culture, which according to some archaeologists is at least 6,000 years old, was not a Vedic civilization but primarily a Tantra-based civilization. The Aryans came later, after the Dravidians.” In other words, Wells' genetic research clearly supports the ideas expressed in the oral teachings of Tantra.

“The Dravidians were called Yueh and Qing in the Chinese literature. Yueh people founded the Dongson culture of Southeast Asia. In Southeast Asia the Dravidians were called Yakshas or Kamboja (Winters,1986). In China the Yueh people founded the Shang Dynasty.

In conclusion the Loulan mummy was probably of Dravidian origin. The Dravidian origin of the Loulan mummy is supported by the Xiaole DNA that corresponds to Dravidian and African DNA”

Researchers have proven that the Dravidians are related to the C-group of Nubia, given the fact that both groups used 1) a common black-and-red ware (BRW);(6) 2) a common burial complex incorporating megaliths and circular rock enclo-sures (5,6) and 3) a common type of rock-cut sepulcher.(5)TheBRW industry diffused from Nubia, across West Asia into Rajastan, and thence to East Central and South India.(11)Singh made it clear that he believes that the BRW radiated from Nubia through Mesopotamia and Iran southward into India.(12 Researchers have proven that the Dravidians are related to the C-group of Nubia, given the fact that both groups used 1) a common black-and-red ware (BRW);(6) 2) a common burial complex incorporating megaliths and circular rock enclo-sures(5,6) and 3) a common type of rock-cut sepulcher.(5)The BRW industry diffused from Nubia, across West Asia into Rajastan, and thence to East Central and South India.(11)Singh made it clear that he believes that the BRW radiated from Nubia through Mesopotamia and Iran southward into India.(12Many linguists claim that the Dravidian languages are genetically related to the Niger-Congo group especially languages spoken today in the Niger Valley and Senegambia region.(5,13–21)

"ANI ancestry ranges from 39–71% in India, and is higher in traditionally upper caste and Indo-European speakers".[24]”

“The Dravidian and Siddi people came from Africa (Winters, 2007a, 2008a,2008b,2010). The Dravidians belonged to the C-group people (Winters, 2007, 2008b). They migrated to Iran and India after 2600BC. The Dravidians carry African haplogroups M1 and  y-chromosomes (Winters, 2008b,2010).”

‘The Rgvedic hymns refer to battles with people called Dāsas and Dayus, who are clearly distinguished from the Rgvedic Aryans themselves (Zimmer 1879, 101,104-118); they are “non-Aryan” (an-ārya),have a dark skin colour, do not worship Indra (an-indra) or perform the Soma sacrifice (a-yajña), and either do not speak (vi-vāc, an-āsya) or use inimical speech (mrdhra-vāc), which probably refers to ritual silence and curses, respectively; their black magic (yātu) is much feared. In two hymns (RV 7.21.5; 10.99.3); Indra is invoked against, or as the slayer of, “those who have the phallus as their god,” or alternatively “tailed deities” (śiśna-devāh; Wackernagel 1905, II, I, 275), which can be reasonably taken to refer to these same enemies .'
