The vegetarian ant
Colony
So, as the title says, I think there should be a mutation system, because it is realistic but more importantly because it would balance a few issues that I have got with the game, so, it would work as a random upgrade or downgrade of a random gene and the closer the parents are genetically the more mutations there would be it would make the game way more dynamic because currently, even if you have like 2 beetles you can reproduce them indifinately and you will end up with an perfectly stable specie which is not really realistic, also, in end game, your species often hit a kind of ceiling, so having mutations would allow you to downgrade some stats, as currently there aren't any way of reliably downgrading stats, it would make end game a lot easier
