Denisovans, Xiahe and Penghu are the only three in that lot that have any genetic link between them, with the tooth from Vietnam being “morphologically similar” to the Denisovans tooth fragment and the two skull caps being guesses based on their robusticity. More testing is needed to group these all together in to a new species, especially so with H. longii, but the researchers with access to the dragon man specimen so far are refusing.
