Could Sino-Tibetan be distantly related to Yeniseien / Na-Dene? (Not a Dene-Caucasian post)
On the Dene-Yeniseien Wiki, Vajda said he was open to other language families being connected.
I know Dene-Caucasian is pretty much long range pseudo-science at this point, but i looked at some vocabulary between sino-tibetan languages and na-dene and yeniseien, and found that Sino-Tibetan has some very similar typology to Yeniseien, and a bit of Na-Dene. I dont have any examples off hand because im writing this kinda on a whim, but some swadesh words from proto-tibeto-burman and old Chinese, and noticed words for body parts seem to look superficially similar to Dene-Yeniseien reconstructions. Maybe its a complete coincidence or maybe im seeing something that's not really there. Sino-Tibetan is very agglutinative and I believe Na-Dene and Yeniseien are supposed to be more synthetic, meaning the morphological evidence doesn't hold up. But damn, its hard to ignore their typology. Maybe they aren't related, but simply shared a convergence zone in the distant past?
