It's not so hard to think about fitness and reproduction on a metaverse. When a Universe succeeds in creating one black hole, its singularity creates a new universe inheriting physical laws from parent but maybe distortions can happen in space giving rise to mutated memetic material. String theory research shows how distortion happens in six-dimensional circular Calabi-Yau shapes that might augment our three-dimensional extended space dimensions. Universes explode, grow and die, but the laws of those universes able to generate black holes live on in their offpring.
Presumably the capacity of a universe's laws to cluster matter lead both to black holes and to enough planets that life is more likely, so that our existence correlates with good universe fitness. Other universes might do pretty badly with getting stuff to stick together.
