Before discovering the EU, I always thought that the Stormtroopers were all clones. Now I know that they're actually all regular human recruits, at least in the current canon, but then why did Lucas in the PT decide to make Clone Troopers almost identical to the Stormtroopers? I've been thinking about this for years, but I've never found a satisfactory answer. Is it because they are the same thing for Lucas? What's the "Lucas canon" answer for this?
