The idea that the Aryans were natives of the Indian subcontinent rather than immigrants from other countries is postulated and argued within the "The Indigenous Aryan Theory".
There is increasing evidence to suggest that historic populations inhabiting the Indo-European regions across Eastern Europe, Eurasia, Iran, And India may have been in cultural contact across millennia resulting in admixtures that contain DNA belonging to the Yamnaya peoples among other native Neolithic Indo-Iranian Agro-pastoral peoples.
There is reason to argue and theorize that these networks of Human tribes could have originated in the Indian sub continent or the Indo-Iranian plateau rather than the other way round.
An eventual migration into Western Europe might have occurred after this event.
A lack of archaeological and genetic evidence, perhaps yet to be discovered, is not sufficient grounds to rule out the theory, or to conclusively/widely accept another based solely on circumstantial genetic forensic studies and instances of scattered artifacts.
The individuals who wrote the Vedas, the first Hindu
religious writings, gave themselves the moniker Arya, which means
"noble." The structural relationships between Sanskrit and classical
European languages were uncovered by nineteenth-century European scholars, who
theorized that all of these languages had a common ancestor.
These researchers speculated that individuals speaking this
parent language originated in central Asia, maybe around the Caspian Sea, based
on additional investigation.
From there, some traveled west to Europe, some southwest to
Turkey, and yet others south to Iran and then India.
Comparisons between the Avesta and the Veda, Iranian and
Indian religious writings, led to the conclusion that these Indian pilgrims
came from Iran.
These writings have a lot of grammatical similarities,
suggesting that the people who spoke the languages were connected.
Thus, the whole hypothesis is based purely on observable
linguistic commonalities and hypotheses about how they developed.
Supporters of the indigenous Aryan idea dispute this
assertion, claiming that the Aryans were the first occupants of India, citing
artifacts discovered in the Indus Valley civilization, an ancient urban network
in northeastern India, as evidence.
Both of these assertions are flimsy at best, and they ignore
the philological data that supports the original Aryan idea.
Political consequences have aided in the establishment of
the Indigenous Aryan idea.
Some supporters are responding to what they consider to be a
colonialist bias in the Aryan migration hypothesis, which was devised by
Europeans and implies that the dominant populations in contemporary India must
have arrived from outside.
Hindutva proponents, for example, argue that all Indians are
“truly” Hindus, and hence belong to the same social group, regardless of their
religious views.
In contemporary India, where Christians and Muslims are not
simply religious communities, but also social and political ones, this
assertion has significant political implications.
Hindutva supporters marginalize Christians and Muslims as outsiders by equating Hindu identification with good Indian citizenship.
