Caste system to have been with us be much earlier, namely in people who were already in India in the Pleistocene era, between 30,000 – 10,000 years ago.
How does one address this question of the origin of the caste system in India?
A recent paper by G. Arun Kumar (of the Genographic Laboratory of Madurai Kamaraj University (MKU) Madurai) and others, published in the Journal PLoS ONE on November 28, 2012 (accessible free online at <PLOS ONE 7(11): e50269.doi:10.1371/journal.pone.0050269>) has taken a combination of genetic and anthropological analysis to address this question.
And it concludes that social stratification was already present among the Adivasis or tribal groups of Tamil Nadu well before the ‘Aryan’ migration.
In other words, it was and has been an indigenous invention.
.......
The results were revealing. They found strong evidence for genetic structure associated primarily with the mode of subsistence; in other words, fathers passed on their occupation and way of life to their sons.
Plus, since the group analyzed specifically one part of the Y chromosome that does not get diluted by recombination, they could do what geneticists refer as coalescence analysis, which allowed them to understand the genetic ancestry of traits and habits.
This let them suggest that social stratification of these indigenous sons of the soil had already occurred between 4000 to 6000 years ago, well before the West Asian influx.
The authors note that “the overall Y-chromosome patterns, the time depth of population diversifications and the period of differentiation were best explained by the emergence of agricultural technology in South India”.
In other words, population differentiation occurred well before the ‘Varna’ caste system. Patrilineage and demographic events seem to have brought in social strata and restricted gene pools, not external intervention.
