Genetic variation increases survival rate. Natural selection works on phenotypes differently. Wide range of phenotypes = greater chance of survival with changing environment.

The Smallest Unit of Evolution. A common misconception is that organisms evolve during their lifetimes. Natural selection acts on individuals, but only populations evolve. Consider, for example, a population of medium ground finches on Daphne Major Island. A mechanism for change in populations..
