(Kinda follow-up to this.…)
I've heard before that if you put 2 ant colonies side by side they're going to attack each other.
But then from the previous question, there could be "sister" ant colonies which (assumingly) don't harm one another.
I can probably see that generation-by-generation colonies would just naturally be either too far apart in space, (or too close in "generation"), to have any fights.
But what actually makes ants decide whether to fight or to not?
And whatever it is, is it a spectrum or a limit..? (i.e would there be a case in which some ants of a colony will fight and some wont?)
