Eh, there are, but not sorted by skin tone or location. If you consider a situation as "home" (the species cycled through crisis/conflict every generation), certain neuro-types pop out as adaptions to this situation cycle parts. A shizophren might look out of place in SF, but he might call us out of place in a warzone.

Its not a good thing though and hardly something to claim pride from or for. Nobody wants to be on team wheel chair.
