In order to evolve, there must be selective pressures which affect the survivability of specimens which vary genetically. I'm unconvinced that one Grimm of the same type differs from another in that way. Learning is for the individual, evolution is for the species.

I was asking myself whether to attempt at a theory regarding Grimm reproduction. Also by real world defininition something is alive if it moves, eats, sleeps, learns among other things. For the sake of simplicity I'll assume that they are technically alive even though they lack souls and have a very mythical vibe to them. The only possible evidence that Grimm eat is what happened to Cardin in volume 1.

My theory for right now is that Grimm do not reproduce naturally but are being generated from an unknown source. This theory is, though bizarre, not far off from the truth, or at least the real story might be similar to this. Obviously they existed prior to humanity as the first episode points out. But I think there's a reason that the Grimm exist. I'm still trying to figure out a more solid theory.
