developmental biology

Presents an introduction to the human life cycle, explaining the stages that people pass through as they grow, including birth, infancy, childhood, adolescence, and adulthood.

The source of the earth's great variety of animals was a scientific mystery until Charles Darwin proposed the idea of natural selection. Nova presents breakthroughs in a new science nicknamed "evo devo" that are linking the enigma of origins to another of nature's mysteries, the development of embryos.

Provides number-related facts about the lives of a variety of animals, such as the the number of antlers a caribou will grow and shed in a lifetime.

Presents four essays in which evolutionary biologist Richard Lewontin provides an account of what his work has taught him about biology and its relevance to human affairs, and promotes his view of organisms as unique consequences of both genes and environment.

Explores aspects of human growth in question-and-answer format, covering such topics as teeth, learning to walk, and the importance of healthy food, exercise, and sleep.

Explains how cells divide and multiply, how humans develop from a single cell to an adult, and how other animals and plants grow.

Describes, with emphasis on the larval stage and metamorphosis, how various amphibians, insects, fishes and other marine animals change as they grow and mature into adults.

An exploration of developmental biology that examines the relationship between cells, genes, and the environment; discusses how discoveries in various branches of biology have allowed scientists a greater understanding of the complexity of organisms; and also covers the phases of human life, origins of major organs, cancer, and more.

Studies the latest biological findings that have helped scientists learn how organisms make themselves.
