Can someone tell me why variation is important in selection?

variation is what makes selection meaningful. Variation can be thought of as "choices". If there is no variation (no options) ,selection wouldn't mean anything as any action of choosing would result in the same type of object being chosen. Thus, variation is the raw material upon which selection acts!
