The second episode of Andrew Marr's exploration of Darwin explores the impact of Darwin’s ideas on society and politics. Darwin’s first port of call on the Beagle was Salvador in Brazil – then a major port for the international slave trade. His experience there confirmed his enlightenment views of liberty and progress and his hatred of slavery. But his theory of evolution that began to take root on that epic voyage would describe a world of conflict, ruthless competition and struggle. It would be taken up and abused by some of the most reactionary movements of the late-19th and 20th centuries. The phrase “survival of the fittest” would help propel Darwin’s theory as a scientific justification for eugenics, enforced sterilisation and genocide. But after the Second World War, Darwin’s theory finds redemption in the United Nations statement on race which confirms Darwin’s long-held view that all humans are members of the same race and deserving of equal treatment. This is further reinforced in the extraordinary work of a small Jewish community in New York who used DNA testing and a voluntary and anonymous form of selective breeding to eliminate a debilitating disease from the Jewish community. DNA testing is the final frontier of Darwin’s Dangerous idea. But the lessons from history suggest that the new choices we face about what to do with the knowledge Darwin has given us when combined with genetics and DNA testing remains a major social and political challenge.

We can all trace our lives back to a beginning. But what defines the beginning? Is it the moment when two cells unite? Or does something have to know it is alive before its life can begin?

In Inferno, Chris Packham explores one of the darkest periods in Earth’s history: the worst mass extinction the planet has ever seen, when as much as 90% of all species died, 252 million years ago. This extraordinary moment in Earth’s history took life to the brink, wreaking havoc and destruction on an unprecedented scale. But somehow, life found a way to bounce back, and a new geological era ushered in the age of the dinosaurs. The story begins with a massive volcanic eruption: the Siberian Traps eruption lasted for two million years and created enough lava field to cover an area the size of Australia. Life in the immediate vicinity was no doubt vaporized, but the fossil record reveals a bigger mystery – a strange ‘line of death’ in rock formations all over the world that indicates almost all life dying out, no matter how close it was to the lava field. Chris uncovers what the latest science reveals about the aftermath of the eruption, and the terrifying series of events that led to the global mass dying. It’s a stark cautionary tale of how rapid climate change can cause whole ecosystems to collapse, but the fossil record also hints at Earth’s miraculous powers of reinvention. Chris discovers clues in rocky mountain ranges to one of greatest deluges in the planet’s history – a downpour lasting on and off for almost two million years that transformed conditions and led life to bounce back in extraordinary style, with the rise and eventual domination of the dinosaurs.

Africa's wildest river is home to the most spectacular wildlife. Hippos fight for territory while herds of elephant, water buffalo and zebra depend on it for life. In the wet season the rains burst the riverbanks and everyone, including people, must move whilst fish swim through the villages. In the dry season the creatures fight over the few pools of water while predators prowl. At its heart it plunges over Victoria Falls and into wild ravines before draining into the Indian Ocean, where storm clouds cycle the water back into the heart of Africa.

In the wilds of the Canadian Rocky Mountains, a mother moose tends to her newborn calf. Spring is in full swing, but this far north, winter is never far away and, with hungry bears and wolves for neighbours, many challenges lie ahead. Local cameraman Hugo Kitching knows this only too well, but he is determined to follow the mother and calf through the four seasons. What unfolds is a very intimate story, and when Hugo finds a second moose calf born late in the year, things take an unexpected and dramatic turn.
