||Great ride this episode. As with all the good plots, it got faster and faster as it went on. Nice message as well, 'under the skin, we're all alike'. I also liked the way the Romulans turned out to be the most reasonable people at the end. It's certainly a brilliant idea to have an explanation as to why so many alien species look Human. At last, 'Humanoids with bumpy heads' make sense. Trek has often been a bit short on 'real aliens'. The Silicon creatures from "The Devil in the Dark" and Odo's people are probably the best examples so far. Perhaps this idea also explains Theropod dinosaurs (presumably including the Voth), Birds, Kangaroos . . .
