There would still be evolution without people being afraid of leaving the towns for fear of swarms of monsters killing them. They said nomads would be enigmatically wiped out due to unknown reasons. I doubt that most people leave towns unless it's nearby or by ship if it's far. There's still animals and dangers in the world. Grimm are too big a danger, there's no balance to them. They just kill with no need to do so if they're not eating humans or using human essence for something.
