Life and Death explores the impact of Darwin’s ideas on our understanding of the meaning of extinction and the interconnections between all life on earth and the environment. Darwin learned many lessons from the giant fossils of extinct animals he found in Argentina and Chile. He eventually revealed to us the unpalatable truth that the logical conclusion to evolution is not perfection but extinction. The extinction of one species creates an environmental niche for new species to fill. Darwin’s theory also gives us vital knowledge we can use to help prolong the existence of our species by respecting the interconnections between all elements of the natural world and the environment. It’s a story in which Darwin’s ideas are taken up with great enthusiasm by his followers throughout the 20th century. But humanity misses one opportunity after another to acknowledge and reduce its destructive impact on the planet. As a result we have set in motion the sixth mass extinction of life on earth. And we are running out of time to do something about it by preserving ecological "hotspots" like certain rainforests which are some of the most productive cradles of evolution. This programme is a warning, but also a celebration, of the knowledge Charles Darwin gave us in his theory of evolution. It confirms that Darwin’s theory continues to inform our understanding of ourselves, our planet and the intricate interconnections between all life on earth.
David Attenborough employs the latest technologies to explore the violence, rivalries and deadly weaponry existing within the world of bugs. This first episode examines the survival tactics of its terrifying residents including killer ants, trap-setting spiders and beetles with the ability to shoot boiling chemicals at their enemies.
The third instalment examines the spiders and others that produce silk. Attenborough visits New Zealand's Waitomo Caves, which are inhabited by fungus gnats whose illuminated larvae sit atop glistening, beaded filaments to lure their prey.
For the animals in the polar regions, autumn means dramatic battles and epic journeys. Time is running out - the Arctic Ocean is freezing over and the sea ice is advancing at 2.5 miles per day around Antarctica. Polar bears gather in large numbers on the Arctic coast as they wait for the return of the ice. Soon, tempers fray and violent sparring contests break out. Meanwhile 2,000 beluga whales head for one special estuary, a gigantic 'whale spa' where they will thrash their snow-white bodies against the gravel and exfoliate. Inland, the tundra undergoes a dramatic transformation from green to fiery red. Here, musk ox males slam head-first into each other with the force of a 30mph car crash as they struggle to defend their harems. Frisky young caribou males play a game of 'grandma's footsteps' as they try to steal the boss's female. Down in Antarctica, Adelie penguin chicks huddle together in creches. When a parent returns from fishing, it leads its twins on a comical steeplechase - sadly there's only enough for one, so the winner gets the meal. Two months later and the chicks are fully feathered apart from downy Mohican hairdos - they're ready to take their first swim - reluctantly though, as it seems penguins are not born with a love of water! And with good reason - a leopard seal explodes from the sea and pulls one from an ice floe, a hunting manoeuvre that has never been filmed before. As winter approaches and everyone has left, the giant emperor penguin arrives and makes an epic trek inland to breed. The mothers soon return to the sea leaving the fathers to hold the eggs and endure the coldest winter on earth.
