Summary: How do humans influence changes in other species? Has Homo sapiens itself stopped evolving? This program explores natural selection as an ongoing phenomenon, showing how evolutionary processes continue to shape the future of all life on Earth. Exploring the competition for resources, territory, and mates that occurs in any ecosystem, the video illustrates how species differentiation takes...

Summary: When On the Origin of Species appeared in 1859, it quickly took hold in the popular imagination-but it also glossed over significant and rather disturbing questions. This program explores Darwin's ideas on human evolution, which he developed and made public toward the end of his life. Science interpreter Jim Doherty reveals how Darwin searched for parallels between humans and animals through a...

Summary: An extraterrestrial biologist would probably not hesitate to classify Homo sapiens as just another chimpanzee. After all, the two species share 98 percent of their DNA-and yet what a difference that two percent makes. This program investigates how such similar primates became so very dissimilar.and how humans, having reached the point where they are little hindered by natural selection, are...

Summary: Marking the 150th anniversary of the publication of On the Origin of Species, this program shows how Charles Darwin developed his theory of evolution and explores its ramifications in today's scientific community. Renowned natural history interpreter David Attenborough travels the globe, examining fresh evidence for Darwinian thought and illustrating why it is more relevant than ever. Viewers...

Summary: By turns charming, alarming, and poignant, this program questions the accuracy of the human evolution theory. Chimpanzees show signs of sophisticated language, advanced social behavior, and other traits thought reserved only for humans-even empathy. No one knows this better than the legendary Jane Goodall: her pride and joy, Frodo, grew up in front of film cameras in Gombe in Tanzania for over...

Summary: 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...

Summary: Could we all be descendants of an Adam-like ancestor? And if he existed, who was he, where did he live, and what did he look like? This program uses sophisticated DNA testing methods to, in effect, trace humanity's family tree. Guided by renowned geneticist Dr. Spencer Wells, viewers learn about the primary tool that propels this quest for a common ancestor-the Y chromosome, which is...

Summary: This program seeks to understand how relationships between living things have promoted the diversity and splendor of life as it exists on Earth today. Predation, competition, and symbiosis are addressed through topics such as the anatomical arms race between predators and prey, the evolutionary benefits of sexual reproduction, and the impact of viruses on creatures ranging from rabbits to human...

Summary: Traveling backward 35,000 years, this program visits a time when glaciers stretched across the Eurasian continent and a highly intelligent and adaptable hominid species roamed the landscape. The Neanderthal was an early ancestor-or, according to some experts, a rival-of human beings; a bulky creature with the intellect to survive an ice age, create art, and practice religion. But over a period...

Summary: In this program, philosopher and theologian Conor Cunningham argues that only extremist viewpoints-Creationism and ultra-Darwinism-make evolution and religion mutually exclusive. Experts from across the gamut of opinions frame the debate and trace its origins, including Father Gregory Tatum of the Ecole Biblique; University of Oxford historian Pietro Corsi; Darwin scholar Nick Spencer, author...

Summary: 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...

Summary: 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...

Summary: Recent findings in the fossil record have, in some scientific quarters, led to radical ideas on evolution. This program presents an intriguing and highly controversial theory: that human development has been-and continues to be-guided by genetic forces within us, rather than by the pressures of our environment. Following the work of paleontologist Anne Dambricourt Malasse and orthodontist...

Summary: In this TEDTalk, geneticist Svante Paabo offers biological proof that early humans mated with Neanderthals after migrating out of Africa. Paabo also provides an overview of mutations and genetic variance, giving audiences a clear picture of the types of early hominids that lived in Africa, Europe, and the Middle East 100,000 years ago. Paabo explores human genetic evolution by analyzing DNA...

Summary: This program analyzes how flight evolved not once but four times, in very different ways. Presenting a number of theories, the program examines how insects, pterosaurs, birds, and bats each took to the sky. Bug wings that may have evolved from larval gills into pond-crossing sails; flight feathers that could have begun as soft down on small dinosaurs; and bat wings that probably developed from...

By focusing on pivotal animals-ammonites, flatworms, sea squirts, frog fish, and bottlenose dolphins, to name only five-and anatomical adaptations such as the eye, the brain, the backbone, and fins, this program illustrates how life populated the seas. Evidence of humankind's evolutionary past is...

Summary: The use of heat and utensils to process food may be more than a by-product of human evolution. According to theories presented in this program, cooking began much earlier than previously thought and ignited a series of changes that shaped our physical and mental abilities. Viewers visit South African caves containing evidence, including tools and charred bone material, that pushes back the...

Summary: Long ago, the oceans were home to all living things. Then some creatures moved ashore. But how? This program outlines the stages of natural selection that enabled water-dwelling animals and plants to survive, and then thrive, on land. Key evolutionary innovations such as exoskeletons and endoskeletons, legs and feet, cold blood and warm blood, lungs, hard-shelled eggs, fur, and live young are...

Summary: 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...
