This program shows the structure and replicating processes of DNA and the effect of genetic mutation; demonstrates the Lederberg Experiment; and recapitulates the evidence provided by fossils and structural and biological homologies that the process of adaptation and the selection of adaptors rests on a wide range of genetic variability. After viewing the program, students should have a general understanding of the general structure and functioning of DNA and of the Lederberg Experiment and its significance, and should be familiar with the range and types of evidence for evolution presented in the review section.

		Selection in Action: Natural Selection 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 su...(more details)		DVD $99.95 DVD + 3-Year Streaming $149.93 3-Year Streaming $99.95
		Selection and Adaptation This program illustrates the selection by environmental constraints of the more favorable variations in a population and the inheritance of these variations by succeeding generations, resulting eventually in a population of plants and animals most of...(more details)		DVD $99.95

		Relationships: Structural Homologies and Coevolution This program presents physical evidence of structural homologies between many types of vertebrates, insects, and plants and explains why these homologies suggest a common ancestry; uses fossils to show the development of specialized structures from s...(more details)		DVD $99.95
