And… really, even the idea that there’s some sort of “ancestral language” is debatable; Rosenfelder himself mentions the possibility in another text. And if Chomsky is right about Language being primarily to structure thought, instead of communication, it’s fairly reasonable that there’s no ancestral language to reconstruct a proto-world of.
