    That’s not exactly how this works…

    Like, I’m assuming you mean it happened but died out, but because what we’re talking about is insanely small, if it happens once, it’s happens all around it at roughly the same time. And it’s not a question of if it’s more efficient than alone, it will be more efficient and out co.oete it’s separate components.

    That’s not the barrier to entry. The barrier is two compatible things finding each other. An extreme change like this can’t be selected for.

    It’s literally a freak chance that it can even happen. Which is why it’s so infrequent

      I think you mean that the initial bit - where the smaller bacterium is swallowed but stays alive in its host - is the “can’t be selected for”. After this, if the chimera survives, then most definitely the natural selection process is in action and selection is taking place.
