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...

Summary: From the promise of eliminating genetic disease to the threat of eradicating human diversity, the potential of genetics to benefit humankind is matched only by its capacity for harm. Using interviews, archival footage, and period film clips, this insightful program traces the history of genomic research and its dark offspring: behavioral genetics, eugenics, and the commodification of children....

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: We may not recognize the plants and animals our children eat. But the real issue is whether the power of the gene will be wisely used, or will it be diverted to the personal ends of those seeking financial profit or political power? Biotechnology is all that stands between a burgeoning world population and starvation. Already, ordinary milking cows are a disappearing species, plants are...

Summary: This program offers an overview of genetics and cloning as they occur both in nature and in the laboratory while addressing the ethical and social implications of genetic engineering. Genes, chromosomes, and DNA are identified, and the process of cell fertilization is demonstrated. Identical human twins are presented as an example of naturally occurring clones. The synthesis of human insulin...

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: How far should people be allowed to go in trying to have better babies? And whose definition of “better” should prevail? This Fred Friendly Seminar moderated by Dateline NBC correspondent John Hockenberry considers the ethical dilemmas facing individuals and society that grow out of prenatal testing and genetic options that may be available in the future—such as cloning. Panelists include...

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. After viewing the...

Summary: Mapping the human genome is one achievement in a long line of scientific milestones. This intro-level program explores discoveries in the 18th and 19th centuries that gave birth to the science of genetics. Focusing on the work of Carl Linnaeus, Gregor Mendel, and Josef Kolreuter, the program shows how the basic laws of inheritance were established, highlighting the importance of Linnaean...

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: How accurate is the term "identical twins"? Can a cell-for-cell likeness between two siblings really exist? And what does that say about the supposed uniqueness of each human being? This program examines the genetics, physiology, and psychology behind such questions as it presents fascinating real-world case studies of identical twin development. Viewers meet monozygotic twins raised apart and...

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: Assume, for the sake of argument, that our species has created everything it needs-all the comfort and protection that technology can provide. Does that mean our biological evolution has come to an end? Not necessarily, says anatomist and anthropologist Alice Roberts. In fact, technology may be driving human evolution, and at breakneck speed. Dr. Roberts meets scientists who are detecting and...

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: 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: 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...
