All living things change. Over long periods of time, species must gradually adapt to meet the challenges of their environment, or they will not survive. This unit helps students explore how and why organisms-including plants, animals, and humans-adapt to their environment. It addresses the difference between physical and behavioral adaptations, as well as distinguishing between behaviors that are instincts and those that are learned.
