This program provides arguments in favor of continental drift and the one-time existence of a supercontinent, shows how isolation can give rise to different species and how species develop in response to their environments, and explains clines and suggests the reason for their existence. After viewing the program, students should understand the significance of the continental drift theory, the purpose of studying inherited variation in isolated populations, and the conclusions about an isolated environment in a species' ancestry that can be drawn from the presence or absence of variation.
