This is called "microevolution." But natural selection is also capable of much more.

Given enough time and enough accumulated changes, natural selection can create entirely new species, known as "macroevolution." It can turn dinosaurs into birds, amphibious mammals into whales and the ancestors of apes into humans.

Natural selection can change a species in small ways, causing a population to change color or size over the course of several generations.
