Off topic: Where does the group wheel come from?

Hi

A buddy of mine asked me this question to which I haven't a clue:

"History of Unix question for you: where does group wheel come from? 

"I unzipped the classes that come with Netscape, and like a lot of
stuff, the files I unzipped were group wheel. I think there might
have been a uid that went along with that, and I suspect they come
out of ucb.  

"Clues? 

Anybody have a historical bent? Where does the group wheel come
from?
