While the look and feel of the Mac interface is different from the PARC model, the Mac's predecessor's (Lisa) interface was not.

I disagree. The look-and-feel of Lisa was much more Mac-like than PARC-like because both Lisa and Mac shared Apple's QuickDraw technology, which was far more advanced that anything PARC had. Some other Lisa technologies were invented by ex-PARC employees who were hired away from Xerox by Apple.

Not to mention that PARC is where the whole idea of a mouse-driven interface originated.

The credit for the mouse is generally given to Douglas Englebart, not PARC.

Which version of the Lisa interface are you referring?

I stand corrected.
