Funnily enough, that Unidan copypasta is 100% correct. I don’t know why, for as long-winded as it is, though, he doesn’t use use more taxonomic names to make it precise: jackdaws are in genus Coloeus, and crows and ravens are in genus Corvus, both under family Corvidae. The apes are the primate superfamily Hominoidea, which Homo sapiens sits under. There, Unidan; that’s all you had to say.
