a theory about the ridges
Well, i have always thought that the ridges are mostly a cosmetical variation of the vulcanoids, as we humans have several "etnias"(i don't know if i have written it well) with differnt colours of skin and varying sizes and even facual features.Think about the oriental's eyes in comparison with the rest of humanity. Maybe the entire romulan race has those distinctive features because they are a whole ethnia who travelled off-world...ehm...does anyone understand my poor english??:confused:
