Contested domains of biological similarities and sociocultural diversity.

Scientists and social scientists often read the same text differently. They also construct categories having the same nomenclature independently. Many of us also work in isolated domains, rarely reading texts researched and documented by others. We conduct our research within the defined format of our disciplines. We engage with others only when contestations emerge and challenge some of the rooted paradigms of each other's disciplines. This paper reflects the reactions of a social scientist to texts on population genetics and attempts to arrive at the genetic theory of the origin of ethnological history of human populations in India. Inadvertently, most of these intensely researched and passionately documented DNA evidence present a serious challenge to the discourse of cultural pluralism and social diversity that the humanist perspective of science and social science takes pride in documenting. This paper is based on secondary resource materials and the methodology adopted is that of narrative research.
