What’s debatable? The definition of ‘evolved’ is ‘developed gradually’.
So. Let’s think about what’s developed gradually on PRS guitars; I can think of a few: CNC, the finish (at least three times that we know of plus the nitro stuff), the bridge (the trem at least three times that we know of, the stop tail with the 2 piece, the adjustable, the piezo, and the materials) the tuners, the nut material, the inlays, the pickups and electronics, the choice of models, and probably dozens of other things.
So except for the fact that they’re largely made of wood, everything that touches the strings, everything that transduces sound, and everything that transmits it to the output jack (including the switching system) has ‘gradually developed’, i.e., evolved.
Honestly, I don’t see what there is to debate.
You may be confusing “evolved” with “improved”.
Improvement? That’s not a requirement in the definition of ‘evolved’ though it’s often taken to mean that.
I suppose you can debate whether the changes in a musical instrument used for self-expression improve it, but that’s going to boil down to mere opinion. It makes no sense to debate opinion. Allow me to demonstrate a debate of opinion:
“I like it better.”
“I don’t.”
“Oh yeah, well f you.”
“Same to you buddy.”
There’s your opinion debate. But the guitars certainly have evolved.
