The Indo-Aryans were united by shared cultural norms and language, referred to as aryā 'noble'. Over the last four millennia, the Indo-Aryan culture has evolved particularly inside India itself, but its origins are in the conflation of values and heritage of the Indo-Aryan and indigenous people groups of India.[20] Diffusion of this culture and language took place by patron-client systems, which allowed for the absorption and acculturation of other groups into this culture, and explains the strong influence on other cultures with which it interacted.
Genetically, most Indo-Aryan-speaking populations are descendants of a mix of Central Asian steppe pastoralists, Iranian hunter-gatherers, and, to a lesser extent, South Asian hunter-gatherers—commonly known as Ancient Ancestral South Indians (AASI). Dravidians are descendants of a mix of South Asian hunter-gatherers and Iranian hunter-gatherers, and to a lesser extent, Central Asian steppe pastoralists. South Indian Tribal Dravidians descend majorly from South Asian hunter-gatherers, and to a lesser extent Iranian hunter-gatherers.[21][22][23] Additionally, Austroasiatic and Tibeto-Burmese speaking people contributed to the genetic make-up of South Asia.[24]
Indigenous Aryanism propagates the idea that the Indo-Aryans were indigenous to the Indian subcontinent, and that the Indo-European languages spread from there to central Asia and Europe. Contemporary support for this idea is ideologically driven, and has no basis in objective data and mainstream scholarship.[25][26][27][28][29]
