David Attenborough presents a guide to wildlife that have adapted to survive in frozen mountain regions. On the high slopes of Mount Kenya, a pregnant High Casqued Chameleon must choose the right time in a daily cycle of tropical sun and frost at night to give birth. The mountains of Japan are the snowiest place on Earth, providing hostile conditions for a lone male Macaque cast out of his troop. In the remote Southern Alps of New Zealand, parrots feed on the dead, while in the Andes, flamingos thrive in high altitude volcanic lakes.

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.

In 1960, a young secretary from Bournemouth, with no scientific qualifications, entered a remote forest in Africa and achieved something nobody else had ever done before. Jane Goodall became accepted by a group of wild chimpanzees, making discoveries that transformed our understanding of them, and challenged the way we define ourselves as human beings by showing just how close we are as a species to our nearest living relatives. Since then, both she and the chimps of Gombe in Tanzania have become world famous - Jane as the beauty of many wildlife films, they as the beasts with something profound to tell us. As one of the programme's contributors, David Attenborough, suggests, Jane Goodall's story could be a fable if it wasn't true. In this revealing programme filmed with Jane Goodall in Africa, we discover the person behind the myth, what motivates her and the personal cost her life's work has exacted from her - and why she still thinks we have a lot to learn from the chimps she has devoted her life to understanding.

Takes us into the world of digestion and its amazingly complex environment.Our health, body shape, mood and even our evolution are determined by the unseen life forms that swarm throughout our bodies. There are worms in your bowels, bacteria in your mouth, fungi in your lungs and even viruses in your DNA.The combined genetic information of all these bugs is more than 150 times greater than our own genes. Their cells outnumber our own by 10 to 1. This collective menagerie is called the microbiome, and in a very real sense, it is the making of us all.

Patrick follows the grizzly bears that are taking a risk with the weather by leaving their winter dens early. Hungry wolves are struggling to bring down their elk prey in the unusually shallow snow. And for great grey owls, it is the iciness of the snow that is hampering their hunts. Yellowstone's winter is always one of the most brutal on the planet. But 2016 saw weather records broken, and the wildlife was forced to adapt to survive. Kate Humble gets to grips with the science behind this remarkable season, from understanding the importance of the snowpack's structure as the melt begins to uncovering why Yellowstone's unique geology poses problems for some grazer's teeth.

Freshwater is often the stage on which millions of animals gather to find a mate. And the cycle of freshwater is the trigger for spectacular mating rituals and fierce competition.
