They can play it off however they want, but that doesn't make what they actually are any less obvious, unless they dramatically change their designs in the anime.
Like I said, Homo Erectus.
Evolution is a major theme, so they have a reason to look like that. It's not the designs that are the problem, but rather certain scenes that could be taken as totally stereotypical (like that car one above). Whether that was the author's intention or not, I have no idea, but they might need to be changed.
Wait there is literally a character named Adolf?
Not exactly an uncommon name in German-speaking countries. The crew is made up of people from everywhere.
