It wasn’t Newton or Einstein or anyone else who inflicted as much harms to religions as Darwin, on his own, did. Darwin started and established a whole new scientific area which largely deals with evolution of species. He, at one stroke, made all those religious stories of God-created-men stories look foolish. To this day, religious authorities dismiss Evolutionary Biology as ‘just a theory’ rather than reality.
Anyway, Darwin never visited India but he was nevertheless aware of India. In fact, he was aware of literature describing Mughal kings’ habit of pigeon keeping and he indeed used pictures from those literature in his studies.
