What is mutation?

A mutation is when something changes in a special way that can affect how it works or looks.

Imagine you have a toy robot that follows commands like "go forward" or "turn left." One day, you notice the robot starts moving backward instead of forward when you press the same button. That change, from going forward to going backward, is like a mutation. It’s not magic; it's just something inside the robot changed.

Think of the robot's instructions as words in a sentence. If one letter gets switched around, like changing "go" to "do," that can make the whole meaning different. That’s what a mutation is, a small change in the instruction or building block that makes something new happen.

It’s kind of like when you write your name and accidentally switch two letters, so it says "Elipea" instead of "Elipedia." You still know it's you, just with a little mix-up. That small change is a mutation, too!
