Natural Selection

Charles Darwin

Gregor Mendel

A body part, feature, or behavior that helps a living thing survive and function better in its environment.

Humans choose a plant or animal to breed based on specific traits.

Studied finches on the Galapagos Islands, and theorized that the 13 species had a common ancestor.

Organisms better adapted to their environment tend to survive and produce more offspring.
