"Over billions of years, ancient fish evolved to walk on land, reptiles transformed into birds that fly, and apelike primates evolved into humans that walk on two legs, talk, and write. For more than a century, paleontologists have traveled the globe to find fossils that show how such changes have happened. We have now arrived at a remarkable moment—prehistoric fossils coupled with new DNA technology have given us the tools to answer some of the...

The nineteenth and twentieth centuries have seen human population grow exponentially. With this growth have come demands for food, shelter and resources. As these needs are met, fragile ecosystems worldwide can suffer. Natural habitats are shrinking, and some scientists say that 25% of all plant and animal species will become extinct in just fifty years. This program looks at the methods and research of scientists who are studying the biodiversity...

Explores the concept of biodiversity and enforces key ideas through science experiments.

A personal account of--and guide to--unlocking the wildlife potential of gardens and other plots of land in lowland Britain. Over the past decade, wildlife author and photographer Paul Sterry has nurtured, both through action and by doing nothing, what has become a small island of flourishing biodiversity in the half-acre garden that surrounds his north Hampshire cottage. By giving nature a free hand, and fostering habitats appropriate to this part...

"Did you know that it stays dark, 24-hours-a-day, for months at a time in the tundra? This frigid biome also has permanently frozen ground! Get ready to investigate some of Earth's most unforgiving ecosystems, as well as the plants and animals that have adapted to survive in them. You'll also learn about the many threats facing this fascinating biome - and what each of us can do to help - all in the pages of Tundra in Danger." --publisher's website....

Introduces the concepts of evolution and biodiversity, discussing such topics as naturalism, genetics, and adaptation.

The Predators are shown not as fearsome enemies of humans or of each other, but, rather, as vital parts of a balanced wilderness ecosystem doing what Nature intended killing to eat. The story stresses the importance of preserving the Predators as an integral part of the beauty, mystery and diversity of life.
