A child born to Tamil parents but raised in Tokyo will dream in Japanese. The hereditary claim is a cultural fiction—a powerful, necessary fiction. In the annals of human linguistics, most languages
Yet, recent studies in epigenetics suggest that trauma and cultural markers can leave chemical tags on DNA. The trauma of colonization, the struggle of the plantation worker, and the resilience of the Sangam poets do echo in the cortisol levels and stress responses of hereditary speakers.
