Historical dates do not match with that of the research results but its documented with some evidence that saint Bhrigu and Manu lived some 10,000 years ago. Manu was especially responsible for writing and compiling 'Manusmriti' that is considered to be the basis of social structure in the region he wanted the society to follow. Cast system is a result of this mass following of Manusmriti as the same was patronaged by the kings as well.
Once the caste system might have come into practice in the subsequent years, that was based on vocation and not on race or colour of skin, endogamous marriages started and thus the mixing of races ( aryan and dravidian ) stopped for some thousands of years.
