The Wolf: Marine Mammal

Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?

In this two-hour special, NOVA captures the turmoil that tore apart the community of Dover, Pennsylvania in one of the latest battles over teaching evolution in public schools. Featuring trial reenactments based on court transcripts and interviews with key participants, including expert scientists and Dover parents, teachers, and town officials, "Judgment Day: Intelligent Design on Trial" follows the celebrated federal case of Kitzmiller v. Dover School District.

Graham Bell and Ed Leigh journey southwards through the frozen province of British Columbia, Canada, towards the home of the 2010 Winter Olympic Games. En route, they travel through remote communities cut off from civilisation through the winter, learning how the locals survive off the land. Leigh and Bell experience this harsh life for themselves alongside miners, loggers and hunters, and find out what it is like to function and work in such harsh conditions. Their journey ends with a gruelling trek on foot through the spectacular Coast Range Mountains into Whistler, one of the Olympic venues.

A scientist explains how the savagery and efficiency of the insect world could result in their taking over the world.

Filmmaker and evolutionary biologist Randy Olson tries to figure out if it is the Darwinists or Intelligent Design supporters who will become a flock of dodos.

Darwin's great insight – that life has evolved over millions of years by natural selection – has been the cornerstone of all David Attenborough’s natural history series. In this documentary, he takes us on a deeply personal journey which reflects his own life and the way he came to understand Darwin’s theory.
