Ati - OK, I see what you mean but I don't think you would get these kinds of differences in a population in 2000 years' time, only with selective breeding. You also suggested that they were special from the beginning (perfect engineers), pilots needed another physical strength perhaps? Well, I also see before me scientist on LV-223 not needing this physique. Anyway, we might get some answers in the next movie . . .
