Adaptation Quote by Stephen Jay Gould
“Natural selection is just three factors - over-production, variation, and inheritance combined to produce adaptation to changing local environments. It's not a principle or progress; it's just a principle of local adaptation. You don't make better creatures in any cosmic sense; you make creatures that are better suited to the changing climates of their local habitats.”

In simple terms: Natural selection fits organisms to local conditions.
