    Pollution also prompts them to attack.

    Terrain can naturally absorb some of it and trees can absorb even more but will eventually die from it, so they’re just a temporary stopgap. Eventually when it reaches the aliens, they too will absorb it until they reach their limit then they’ll organize attacks.

    That being said, I can’t remember if it’s specifically pollution they absorb that causes them to evolve into stronger forms or if it’s any pollution you produce that does it.

      Seems to be the latter:

      The evolution factor is increased by three kinds of events:

      • The passage of time very slightly increases the evolution factor.

      • The global pollution production increases the evolution factor.

      • Destroying nests significantly increases the evolution factor.

        I’ve never understood how destroying nests logically accelerates evolution if none of them survive

          This other nests pickup on pheromones that tell them what the others died from.

          That or its a hive mind so they learn from each encounter.
