Variation
Variation explained in an easy to understand way:
Imagine you're trying to find the perfect pair of jeans, but every store has slightly different fits, even though they're all labeled the same size. This is similar to how individuals of the same species can have variations, even though they belong to the same group. Just like how the jeans differ in length, waist size, or cut, members of the same species can have differences in traits such as height, color, or behavior, highlighting the natural variations within a single species.
