Summary: Our body is composed of billions of cells, but how does each cell know what to become? This program starts with the nucleus of a single cell and then explains the other components the cell needs to function: chromosomes, genes, DNA, and ribosomes. From hair color to height, our genes determine who we are. This program explores, through animated graphics, all of the basic genetic building blocks...

Summary: As the 19th century gave way to the 20th, genetics came into its own as a science. This intro-level program shows how the development of the microscope pushed genetic studies forward, and includes in-depth discussion of early cell theory, particularly the first observations of meiosis and mitosis. Exploring Thomas Morgan Hunt's findings involving Drosophila mutation, the program covers...

Summary: Darwin's theory of natural selection, to be valid, required explanations for both the origin of variation and for the inheritance of variants. John Maynard Smith explains Lamarck's theory of the inheritance of acquired characteristics (in which Darwin believed), Weismann's theory of separate inheritance lines of germ and soma, Mendel's experiments and explanations, and the discovery of the role...

Summary: When you look at a family photo, the resemblances, even across several generations, can be striking. What role do genes play, and why aren't siblings identical (and why are some)? This program explains how the formation of sex cells, from the first gamete to chromosome pairs, determines our genetic makeup. Deviations such as cystic fibrosis, Huntington's disease, achondroplasia, Klinefelter...

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: 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...

Summary: DNA testing has become a standard tool in genealogical research, but it takes more than saliva swabs and lab reports to truly understand one's ancestry. In this program, two young New Zealanders of Polynesian descent undergo DNA sampling, wrestle with the surprising results, and then embark on a journey of discovery, searching for their roots across the Pacific and into Asia. Their voyage-by...

Summary: This program introduces the concepts of naturally occurring and artificially induced mutagens, demonstrates how X-radiation and chemical additives can produce genetic mutations, introduces Dr. Maclyn McCarty (one of three researchers who identified DNA as the substance that transformed one variety of Pneumococcus into another), and shows how DNA is extracted and precipitated.

Summary: The oceans are life's laboratory, the global test tube where trial and error meet cause and effect. 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: This program illustrates how natural selection works to enable a species to adapt to adverse environments; shows how human breeding of desirable varieties-which antedates by millennia any theories of genetics or evolution-often overrode natural selection; demonstrates how species can be changed by artificial selection and in response to human interference with the environment; and explains the...

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: 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: 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: 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: Dissecting the phenomenon of altruism-as well as its mirror image, the instinct of self-preservation-is perhaps best accomplished with real-world case studies. This program does so as it documents the aftermath of the 2004 Asian tsunami. Following four independent relief workers in the hardest-hit areas of Sri Lanka, the film captures scene after scene in which the most idealistic and pragmatic...

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...

Chimpanzees show signs of sophisticated language, advanced social behavior, and other traits thought reserved only for humans-even empathy.

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...
