The releases we have of Copland are "pre-alpha", and they need System 7.5 to bootstrap them. They are driver-development releases to help companies write copland drivers for their hardware. How they're supposed to do that when the system doesn't stay up for more than a couple moments is a mystery to me, but who's asking me?
Copland is totally different than any other OS that runs on Macs; it looks like MacOS 8, and it's not UNIX-based, but it sits on top of Mach (like MacOS X) and (in the versions we have) doesn't do much but show a pretty-looking boot screen (big MacOS face starts out blurry and comes into focus) and crash a lot.
The ResEdit 3.0 beta that's floating around is a native Copland application and should get the fancy Copland features (multitasking and protected memory) if and when it ever runs.
