<p><b>New page</b></p><div>Can occur at random, or if the conditions show that the current dna is failing overall, a forced mutation can occur. Mutations cause changes to your robot's behavior through the DNA. Mutations are key to the theory of Darwinism, it can be both effective and lmiting, depending on the effectiveness of your bot's DNA. .mrepro causes the bot to reproduce with an imperfect DNA.</div>Rsucoop
