We've seen "black" Vulcans, Romulans and Bajorans, "Asian" Romulans, "white" Klingons (TOS-style, anyway) -- are we to take this as an indication that these species also evolved along similar racial/ethnic lines to humans? Are these superficial differences of any importance to alien cultures? Have they been?
