Films for the Humanities and Sciences - Relationships: Structural Homologies and Coevolution

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 simpler forms; shows by means of homologous structures that what appears to be a new or different organ may be a variant or modification of something existing in an ancestor; and presents evidence for coevolution from examples where entire orders of organisms dependent on one another have developed corresponding structural modification. After viewing the program, students should understand the concepts of structural homology and analogy and be able to cite some examples of each, and be aware of the principal types of evidence to suggest or support the theory of coevolution.
