Aryan Invasion of India: Myth or Reality?

 DNA evidence has shed new light on the origins of the Indian people, the Hindu religion and the Sanskrit language. Pastoralists of the Andronovo culture from the Bronze age steppe invaded India from the North West and brought Indo-European languages to the Indian subcontinent. These pastoralists were ethnically white people, and they mixed with Indians to create the modern genetic diversity of India. This theory has been developed over 200 years, and has often been attacked as a colonial fable or even as Nazi propaganda, but now genetic science has vindicated the Victorian scholars who said the roots of the Aryans lay in the Corded Ware culture of Europe.
