Think of it in terms of a bag of coins. If they are all the same any removal of ten will give the same result and no advancement of those remaining.
If the bag has a mixture, then the value of those remaining in the bag after ten are taken out becomes a variable depending on the selection. In a bag where coins of more value have an innate trait of being harder to extract, then the net value of the coins remaining in the bag increases after the removal of ten coins of lesser value above the net value of random selection.

If I make a natural selection in choosing a mate..I'm sending their genes into posterity. If I have three mates to choose from and they are identical (no variation) it doesn't matter who I choose. But if they are different (and they are) I choose one or the other because I like something about them, they are stronger, better looking, smarter...I decide what qualities are important in my environment and choose to select accordingly.

Because if u dont have a large enough pool to choose from eventually u'll be stuck with the same alleles so there's no selection. Nothing to choose from.

Without variation, there would be nothing to choose or select.
