The Rules of Life

Evolution. Competition. Mass extinction. Three fundamental rules have driven the rise and fall of life on Earth for over four billion years.

The First Frontier

For billions of years, land on Earth was uninhabitable. But in the seas, predation allowed species to thrive before — and after — two mass extinctions.

Invaders of the Land

Sprawling moss, towering trees, flying insects, limbed amphibians: Early species vied for domination as the land went from hostile to hospitable.

Out of the Ashes

The dinosaurs met their end with a cataclysmic asteroid impact. Rising from the ashes, birds reinvented themselves into a dynasty 10,000 species strong.

Snowball

In Snowball, Chris Packham tells the story of the astonishing moment in Earth’s distant past, when almost the entire planet froze – a glistening ‘Snowball Earth’ in the dark void of space. With ice wrapped around the planet to the equator, the chances of life surviving hang in the balance. Earth’s terrifying journey into the deep freeze started with fire, not ice. 800 million years ago, long before the age of the dinosaurs, before there was even animal life, the giant supercontinent Rodinia broke up. Earth’s vast powerful tectonic forces ripped the land apart, kicking off a series of events that resulted in huge amounts of carbon dioxide being sucked from the atmosphere and sending global temperatures plummeting. This plunge into the deep freeze couldn’t have come at a worse time. The very first forms of complex life - the ancestors to the amazing life we see around us today - were evolving but, as the planet froze to the equator, it looked like their days were numbered. Happily, Chris discovers that after 50 million years locked in ice, volcanic eruptions drove a great thaw. Life broke free from the ice and soon made a giant leap, from the microscopic, to the first animals big enough to see and touch.

Life and Death

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.

Return of the Giant Killers: Africa's Lion Kings

In southern Africa, a pride of lions has rewritten the rules - by learning to take down elephants. In this follow up to Africa's Giant Killers, we join the pride at the start of the rainy season. As the elephants depart, a catalogue of dramatic events unfolds. The pride males turn against each other, an inexperienced mum puts her new born cubs in mortal danger, a rival group of lions challenge the pride for its territory and, when lightning strikes, fires burn day and night. When the dust eventually settles, the pride is left with only one choice - to face their old foe the elephants or risk starvation. The final showdown awaits.
