Darwin’s Hypothesis (pg. 72) Individuals with certain inherited variation are better suited to life in their environment than other individuals.

Adaptation (pg 72) Any heritable characteristic that increases an organism’s ability to survive and reproduce in its environment.

Fitness How well an organism can survive and reproduce in its environment.

Natural Selection
