Tập 7
THE FOUR BILLION YEAR WAR explains how both conflict and cooperation have helped shape the species that today populate our world. And it profiles the winners and losers in this epic evolutionary contest — from the massive dinosaurs who disappeared long ago to the humble bacteria that have survived for billions of years virtually unchanged.
Tập 9
For billions of years, life on Earth has been engaged in its own ETERNAL ARMS RACE, the subject of Part 3 of NATURE’s TRIUMPH OF LIFE. As predators became better hunters, their prey also evolved better defenses.

Tập 6
Each October, the remote Canadian town of Churchill in Manitoba plays host to some very unusual guests. More than a thousand hungry polar bears gather there to await the refreezing of Hudson Bay and then move out on the ice in pursuit of their traditional winter diet of seal. The world's largest land carnivore, polar bears can be very dangerous for humans as well as sea creatures -- but for tiny Churchill, they also are a tourist-dollar bonanza.
Tập 10
Life may be a contest in which only the fittest individuals survive, but cooperation has also played a key role in evolution. WINNING TEAMS takes a close look at the alliances that animals have forged — with others of their own kind and very different organisms — in a bid to stay alive. In fact, teamwork occurs everywhere, from flocks of birds and herds of wildebeest to colonies of ants and termites.
Tập 5
Life on the savannah of southern Tanzania is a study in contrast between rainy and dry seasons. When water is abundant, the wildebeest at the rivers provide food for the lion population, while the buffalo graze contentedly on the succulent grasses in the hills. The two great adversaries -- lion and buffalo -- can keep their distance.
Tập 11
Hearts, eyes, flippers and wings — evolution has forged many remarkable body structures. But none is more amazing than the brain, that bundle of nerve cells that allows us to sense our surroundings, sort out information, and make decisions. Indeed, the great importance of BRAIN POWER to evolution is the subject of this week’s installment of NATURE’s TRIUMPH OF LIFE series.
Tập 4
The enigmatic subjects of NATURE: The Urban Elephant, Asian elephants are losing territory to the inevitable process of deforestation. Industrialization all over Asia has hurt the mahouts, or elephant drivers, so that the trained elephants and their riders are being driven into major cities such as Bangkok to earn a meager living receiving donations and food from curious tourists.
Tập 12
This sixth installment focuses on the mass extinctions that have occurred over time. Though attention is paid to the factors that probably led to the demise of the dinosaurs, far more time is devoted to examining a wide variety of land and sea creatures that are continuing to fight off extinction. Climate changes, the birth of more highly evolved life forms, and changes in ocean currents are just a few of the factors that can play a major role in determining which species will prevail. Scientists and historians share their thoughts about which of today's species are most likely to remain triumphant over the coming millennia.
