[00:00:00]Mutations might seem like a bad thing, but actually they can also be neutral or even beneficial. For example, a species of yellow grasshoppers might mutate and become green, which makes them blend in with the grass and get eaten less. Over time, you can expect to see more and more green grasshoppers as their fitness has increased. Not that kind of fitness, fitness as in they can have more offspring because they get eaten less.
