"You" as an entity are really just a process emergent from chemical reactions on some area, and your "will" is just the result of feedback between many regions of that process and outside stimuli.
Biological evolution is a process happening in more dispersed reactions, but still has all manner of internal feedback mechanisms and responds to external stimuli.
I don't see how you've drawn a meaningful distinction between them, except to say that one os easy to observe in total (eg, you can draw a box around it) and is sort of like you, so you feel you can understand it.
Homeostasis and physical locality don't seem partocularly germane traits when discussing whether or not something has a will.
Further, you (just as evolution) are ongoing until you're not, and "physically discrete meaning" sounds like a dressed up "well, I just know it when I see it".
