I'm working on a conlang that (in my alternate history) was substrate to the dravidian and indo-aryan languages. Is there a list anywhere of the language changes, in order, from PIE to sanskrit? or for that matter, any proto language to its modern descendant/s? I've done plenty of googling and all that's turning up is article about the literary history of a language, maybe a couple notable sound laws, but no order or anything really useful.
