There are enough physical similarities for that to make sense, but we should keep in mind that parallel evolution is a thing that happens- two entirely disparate organisms can end up with remarkably similar body plans because said body plan is most effective for their ecological niche- and there are numerous sentient races that patently don't share a common primate ancestor with hyurs et al. There's no way Amalj'aa, Mamool Ja, Ixal, Sahagins, Qiqirns, or even Sylphs come from the same immediate primate ancestors. Â There's precedent for Miqo'te not having a common ancestor with elezen, roegadyn, hyur, and lalafell.
My own point of view on this -- not my opinion, but what I've chosen to think based on the story presented to me, in which I am either correct or incorrect and willing to discuss it -- is that all the player races are in fact the same species. They are different races of the same species, that species being human. There are references to the "races of man" and "mankind" in-game, and the physiological differences of the player characters (even Roe versus Lalafel) are minor compared to those between the "races of man" and the beast tribes.
Put simply: player characters are all humans and the beast tribes are not, thus the distinction. Player characters share an single ancestor. The beast tribes have alternative origins. That's why they're beast tribes.
This is why I'm confident in saying that Miqo'te are primarily human and secondarily beastly. The beast is there, but it's subservient to the human-ness.
