It's an understandable thing to get confused about, because Nitowikwe and Wawlika are basically the only examples of this.

If we saw some hrothgar casually hanging out with the Hanuhanu in Kozuma'uka that would bridge that, but the only places we see a diversity of races are in the places where we'd expect a bunch of cultural crossover anyway.
