Idk this 1.

Answer 3

Okay the simple answer is:
Phenotypes.

Before I explain anything in depth you have to understand what natural selection is:
Natural selection is when nature selects individuals who are best fit (adapt) for the environment. (Textbook definition.)

You can consider \(phenotypes\) another word for \(appearance\).
Examples:
Eye color.
Height (Tall or short.)
