Selection in Action [electronic resource]: 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 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.

African-American Lives 2 [electronic resource]: The Past Is Another Country

The science of genetics has created an exciting new dimension in the study of black history and heritage. In this program, DNA analysis leads to fascinating discoveries about the lineages of participants-and the ancestry of host Henry Louis Gates, Jr., himself. A groundbreaking study links Professor Gates to a powerful ancient Irish warlord, while genetic evidence suggests that Peter Gomes' direct paternal line reaches back to a Portuguese Jew who fled the country in the early 1500s to escape the Inquisition.

The Evolution of Human Purpose [electronic resource]

All other life forms except humans exist to propagate themselves and pass on their genes; humans alone work to other ends. In this lecture, Richard Dawkins distinguishes between the result of eons of natural selection which has resulted in, say, a bird's tail, whose purpose is to enable the bird to fly-purpose with a survival value-and deliberate design, like an airplane's tail. Dawkins shows the relationship between the two in explaining the evolution of human purpose.

The Origins of Darwin's Theory [electronic resource]

Sir Andrew Huxley-grandson of Darwin's great defender, Thomas Huxley-describes Darwin's motivations, discoveries, and search for a logical theory to explain his observations of both geological and biological evidence in South America, focusing on Darwin's importance as the first to present strong, scientific evidence for descent with modification and to posit a plausible mechanism for its occurrence, namely natural selection.

The Record of the Rocks [electronic resource]

This program shows the process of sedimentation, which has preserved those life forms extant at the time the rock was formed and-most strikingly where the Colorado River has cut through the Grand Canyon-exposes a veritable history of life on earth; presents the stratified evidence that simple organisms populated the earth first, followed by increasingly complex forms; demonstrates modern techniques for dating rock samples; and explains why fossils provide important evidence of the theory of evolution. After viewing the program, students should understand the mechanisms that made possible the Colorado River rock record, where the oldest and youngest rocks are and why, how the absolute age of rocks is determined, and the nature and extent of the record provided by rocks.

Fossils [electronic resource]: Reptiles and Mammals

This program presents fossil evidence for the evolution of reptiles and amphibians; explains the reasoning processes scientists must use when no direct evidence is available for examination; illustrates field techniques for collecting fragile fossils for transportation to the laboratory, where examination can take place under controlled conditions; and traces the evolution of some modern mammals back through time. After viewing the program, students should know which major features distinguish amphibians from reptiles, when and for how long reptiles were the dominant land animals and by whom they were replaced, and recognize the feature in the fossil remains of land reptiles that may indicate that they gave rise to mammals.

Darwin's Theory Today [electronic resource]

Since Darwin's day, explanations for the causation of evolution have come and gone, Lamarckism, mutationism, and the existence of a built-in mechanism driving to perfection all dismissed for lack of evidence and the proofs of molecular biology. Ernst Mayr examines and evaluates the modifications and adaptations to Darwin's theory of natural selection, to determine whether the resulting synthesis is indeed still Darwin's theory.

Evolution [electronic resource]

Since Charles Darwin formulated his theory of natural selection, our view of the world has changed. Although Darwin's theory itself has "evolved," scientists agree that living species slowly but surely diverged from common ancestors. This program begins with a segment on fossils, one of the most convincing proofs of evolution. It then retraces the major steps of evolution as they were uncovered by science. It also presents the major theories of evolution.
