In this dazzling companion to the most important PBS television series this fall, award-winning journalist Carl Zimmer collaborates with leading scholars to tell the compelling story of the theory of evolution-from Darwin to 21st century science Darwin's The Origin of Species was breathtaking-beautifully written, staunchly defended, defiantly radical. Yet it emerged long before modern genetics, molecular biology, and contemporary findings in paleontology. ...

In the animal kingdom, survival is the name of the game--and not everything is as it seems. A number of animals rely on particularly clever tricks to fool predators or prey. A baby bird mimics a poisonous caterpillar. A moth escapes bats by making sounds that interfere with the bats' echolocation. A tiny rain forest spider builds a big spider "puppet" out of bits of dead leaves, insect parts, and other items. Find out more about some of nature's most...

Explains the principles of biology and includes sample questions with answers.

Continues: Life on earth. The story of the Earth's surface and its colonization by animals and plants.

Provides an overview of biological topics, discussing cells and the building blocks of life; describing the characteristics of living creatures, from viruses to mammals; and examining body parts and plants.

The Oedogoniales are remarkable filamentous green algae. Their method of cell elongation is unique, utilizing a donut-shaped ring of soft wall material which is stretched to form the new daughter cell. While Oedogonium is a simple filament, the related Bulbochaete and Oedocladium are branched and Bulbochaete differentiates long hair cells. The zoospore is large and multiflagellated. Sexual reproduction is oogamous and either “macrandrous” or “nannandrous.”...

Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Computer animations take you inside a clump of moss plants to illustrate external structure. You are then transported inside the tips of male and female stems where gametangia (sex organs), sperm release, fertilization and embryo development are illustrated..

Mitosis requires cells to organize numerous jumbled chromosomes and then separate them with absolute fidelity into two equal groups. How this extraordinary process is accomplished is still poorly understood.. This video reveals the events of mitosis at a level of detail usually seen only in research laboratories. In addition, two Appendices show mitosis in a classical system, the diatom cell, and some experiments on living cells that illustrate why...

Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Three dimensional animations take you in and around reproductive structures such as the sorus, sporangium, and antheridium and archegonium. You see dynamic events such as spore formation, spore release, prothallus formation, sperm release, fertilization and embryo growth..

For convenience, biologists divide living organisms into five “Kingdoms”: the Monerans (bacteria and cyanobacteria), Protists, Fungi, Plants, and Animals. The Kingdom Protista includes a vast array of tiny eukaryotic cells that lead complex and extraordinary lives far from the eyes of most humans; a dedication to microscopy is vital to see them in all their splendor. This video is a unique resource introducing the viewer to a considerable range...
