You have to understand that the two are similar for a reason. 40k was originally meant to simply be a Sci-fi version of FB. Back then 40k still had Squats, which were meant to be thesetting's facsimile for Dwarves, and the Hrud looked like the Skaven in early editions. The Squats were removed from the setting, and the Hrud's apearance were changed because GW wanted to distance 40k from the original, making it its own Sci'fi series rather than the fantasy setting in space.
