Summary: This program examines three main activities of the cell: energy storage and release, protein synthesis, and cell reproduction. Students take a closer look at important organelles such as mitochondria and chloroplasts, and the roles they play in cell metabolism. Also examined are proteins, amino acids, ribosomes, DNA, RNA, genes, chromosomes, transcription, and translation. Mitosis is clearly...

Summary: In this virtual journey through the cell, viewers become familiar with cells and their properties. The program describes and shows examples of cells of many shapes and sizes, and explores the structure and functions of different types of cells. Eukaryotes and prokaryotes are defined, and plant and animal cells are compared. Emphasizing cells as the basic building blocks of all organisms,...

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: 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: 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: 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: 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...
