NATURAL SELECTION

• Process by which individuals that are better adapted to their environment are more likely to survive and reproduce
• Scientists compare the DNA of living organisms to find similarities among the species to see how closely related they are
• Remains of an ancient organism or an imprint left behind by an organism
• Most species produce far more offspring than can possibly survive
