Are my sophont species, the Chamkatwe, plausible from a solely evolutionary standpoint?
Their information
Art by my very good friend @/living-dead-guyy on Tumblr.
This question is solely about whether they could hypothetically evolve, not about their culture or anything else.
Edit: for any new commenters, the Chamkatwe are primates, specifically roughly 16-inch-tall adaptiform primates distantly related to tarsiers and lemurs.
