I'm a bit confused, if you kill biter nests as they "smell" your pollution wouldn't that mean that you are effectively cutting them off from evolving due to your pollution? Or at least making it easier for you to not over-evolve them with your careless pollution and thus making it easier?

Evolution is triggered by the creation of pollution, not it's absorption. This mod has no effect on evolution.

Oooh I see now, maybe mention that in the description so it is a bit more clear how it functions!

That's how evolution works in vanilla!

Also I misspoke: Evolution also advances when nests die and this mod kills nests, so this mod does have an effect on evolution.

Yeah I figured that after I posted my message XD. 1600 hours in this game and I always thought that the direct contact with pollution was what caused them to evolve and attack in the first place - welp, I learned something new!
