@blog_supplement I know you are making a case above that Indo-Aryan has had a long tradition of retroflex sounds
But you also suggest that the more archaic forms of words in Vedic are usually dental consonants
In contrast, in the Dravidian languages, retroflexes persist
E.g. muraLidharan in tamil vs muralidhar in Hindi
