individual’s ability to survive and reproduce in a

particular environmentAdaptation

Species

Page 4: Chapter 7 Evolution of Living Things. A characteristic that improves an individual’s ability to survive and reproduce in a particular environment Adaptation

characteristics within a population change

over generations such that new species sometimes arise

Evolution

of an organism preserved by

geological processes

The process by which individuals that are

better adapted to their environment survive and

reproduce more successfully than less

well adapted individuals do; a theory to explain

the mechanism of evolutionNatural Selection
