Meet slime molds: the brainless blobs that can learn, make decisions, and navigate mazes. Who says you need brains to be smart? Extremely primitive life-forms called slime molds can navigate mazes, choose between foods, and create efficient networks—no brain required. New research on these organisms, which are neither plant nor animal, could help reveal the fundamental rules underlying all decision making.

As the Serengeti starts to dry out, competition hots up between the families we were first introduced to in Episode One. The strong females take centre stage, dealing with wayward males and fighting for the survival of their kin. Lioness Kali and her sister are enjoying time with their seven cubs. Together, hunting is much easier and life is good. But their happiness is short-lived as they are being tracked by Sefu, a male lion from the pride. He takes their food and then relentlessly pursues them, but what does he want? A new family has moved into the Serengeti: Kike, a first-time cheetah mother with three tiny cubs in tow. If her first litter is to survive, she must learn the skills of motherhood fast. Not only must she learn to hunt and keep her cubs safe, but she must keep them away from the other predators who are out to get them. Bakari the baboon struggles to raise the baby he rescued when its mother was killed and desperately tries to find a female to help him raise his motherless baby. Nalla, the elephant matriarch, is worried for the safety of her baby when a group of huge male elephants come to fight over one of the family's females. A young female ostrich attempts to raise an enormous brood of chicks whilst being watched by the hungry eyes of the hyena leader, Zalika. As pressure builds, Kali decides that for the sake of her cubs she must confront the male stalker Sefu – but it's a dangerous decision. Bakari is threatened by the leader of the troop when their rivalry escalates and the baby is put at risk. Will a kind-hearted female called Cheka help him raise the baby? Only the strong survive in the Serengeti, and the mothers are the toughest of the lot.

This episode is a pioneering exploration of the latest discoveries concerning the Amazon - by far the greatest river on Earth. It is the river of superlatives, flowing more than 4,000 miles from the Andes to the Atlantic. Its 1,100 tributaries drain the greatest river basin on the planet and along its incredible journey it collects and transports one-fifth of the world's fresh water. Due to its enormous size, it still hides secrets.

Beginning in Antarctica, Emperor Penguin chicks are abandoned by their parents as spring begins and must find their way across the treacherous sea ice to the rich waters of the Southern Ocean. In the Himalayas, the world's fluffiest cat hunts for gerbils and voles, while in the boreal forests circling North America, Europe and Asia, a Siberian tiger is on the lookout for black bears.

A unique celebration of one of Earth's most iconic birds. For the first time, we meet the entire penguin family - all 18 species. This colourful cast of characters may seem familiar, but their incredible diversity won't fail to surprise. New Zealand's lush green forests might not be the first place you would expect to find penguins, but it was here the penguin family first evolved 60 million years ago, and there are now more species living here than anywhere else on earth. One quirky-looking resident is the Snares penguin, which likes nothing more than a spa treatment. In Cape Town, the African penguin has adapted to the modern world, strolling the city streets with all the other commuters. And, against all the odds, one of the smallest members in the family, the Galapagos penguin, has found a way to survive the sweltering heat of the equator. One of the biggest secrets to the penguin success story is their remarkable parenting skills. Adelie penguins perform the longest penguin migration on earth, over 6,000 miles, to find the perfect nesting site. Ninety-nine per cent of them return to the same nests each year, but after a hard winter their stone nests need some serious renovation. Other species are sneakier, stealing their neighbours stones the moment they turn their backs. The fastest penguin on the planet is the gentoo, reaching speeds of 22mph and diving to 200 metres. Short feet that act like rudders and a streamlined body allows them to shoot through the water, while fused muscular wings act like paddles. Penguins are supremely adapted to an aquatic life, spending 75 per cent of their lives in water, but all penguins have to walk at some point, so to get around they have developed the infamous waddle. This bizarre locomotion may look inefficient, but surprisingly it actually works in their favour. Whilst we get 65 per cent of the energy back with each step, penguins can get up to 80 per cent, so the waddle is more efficient that our own walk. Over millions of years, penguins have mastered life on land and in the sea, but we are now changing the planet faster than ever before, and some penguins are struggling to keep up, so technology is being used to locate and observe new colonies from the equator to Antarctica. This is the family penguin as you have never seen them before.
