The incredible anticipation of the annual great migration is being felt by all of the Serengeti's families as they wait with great desperation for it to arrive. The land continues to get hotter and hunger start to bite as food becomes ever more scarce for the predators. But life continues, with Kali the lioness and her sister entrusting their cubs to their new male babysitter, Sefu, with near-disastrous results. Bakari the baboon is shocked when a trip across the river to collect crocodile eggs looks like it will end in tragedy for his new female, Cheka, and the adopted baby. His rivalry with the troop leader then puts him and the baby in more danger. A family of wild dogs moves in, led by male Jasari. With a huge litter of pups, Jasari is ready to take advantage of the coming feast, but until the migrating herds arrive, it is a struggle to survive. Shani, a female zebra, is leading her family on the great migration. She is forced to stop temporarily to give birth to her foal, but as soon as he can run, they are off again heading towards the great river. When the herds finally arrive at the river, they find it teeming with crocodiles, and zebra mother Shani has to decide how and when she can take her newborn foal across the treacherous water. Lying in wait and watching them carefully is a large mother crocodile, who is determined to eat them if they try. With the great migration now in full flow, there are winners and losers on both sides. The awe-inspiring spectacle it brings are part of the deep seasonal rhythms that govern all life in the Serengeti.

The older a species, the better it is at adapting to change. From the ancient lineage of sharks, who've evolved into perfect predators, to the living fossil known as the bichir, get a closer look at some of nature's enduring evolutionary masters.

From the food on our tables to the fuel in our cars, crude oil seeps invisibly into almost every part of our modern lives. Yet many of us have little idea of the incredible journey it has made to reach our petrol tanks and plastic bags from its origins millions of years ago.

Even after thousands of years of ice crushing the northern hemisphere and temperatures of 20 degrees lower than those of today, many of the great giants of the ice age still walked the earth. It was only when the world had warmed up again that mammoths, woolly rhinos, sabre-toothed cats, giant ground sloths and glyptodonts finally became extinct. Professor Alice Roberts sets off on her last voyage back to the Ice Age to discover why.

From crowned lemurs to Bornean orangutans, the higher we move up the primate family tree, the closer their behavior mimics our own-especially when it comes to family and raising young. Peer into the astonishing adaptations that highlight the lengths primates will go to preserve and build family bonds.

Blue Planet II explores parts of the ocean that nobody has ever visited, encountered extraordinary animals, and discovered new insights into life beneath the waves. In Our Blue Planet, Sir David Attenborough examines the impact of human life on life in the ocean. In this final episode, we uncover the impact that our modern lives are having on our best-loved characters from across the series, including devoted albatross parents unwittingly feeding their chicks discarded plastic and mother dolphins potentially exposing their newborn calves to pollutants through their contaminated milk. Scientists have even discovered that increasing noise levels may stop baby clownfish finding their way home.
