David Attenborough investigates two shells that have proved to be winners in evolution: the tortoise's shell and the shells of birds' eggs. The ostrich egg is so strong it is possible for a person to stand on it without it breaking, but how does the chick break out of this fortress? The evolution of the tortoise shell was for a long time a mystery and this bony box offers a lot more than just protection.

Stretched to the Limit

Some animals appear to have taken Nature’s gifts and stretched them to extreme limits. With these two natural curiosities one creature, the giraffe, has ended up with a super-stretched neck, the other, the chameleon, a super stretchy tongue. In both cases nature has found a way to turn the ordinary into the extraordinary.

Young Wrinklies

David encounters two examples where Nature has tinkered with the aging process to alarmingly different effect – the first grows old while trapped in a young body while the second looks old from birth but might hold the key to a long life.

Seeing the Pattern

Zebra stripes vary subtly between the different species but there is one group of animals that has evolved colourful patterns of seemingly infinite variety, the butterflies. In this episode David looks at two examples of animal patterns that have bedazzled and baffled science for a long time, and uses modern tools to unlock their secrets.

A Curious Hoax?

David Attenborough highlights the curiosities that have led to accusations of forgery, but have ultimately helped assist the rethinking of evolution. When early explorers brought the first specimen of a duck-billed platypus to England in 1799, it was considered so bizarre it was deemed a hoax. Similarly, the midwife toad became the centre of a scientific storm in the 1920s that led to accusations of fakery.

Animal Frankensteins

Hybrids can be bizarre and they can be deadly. We look at two hybrid animals that owe their existence to human interference - the pizzly bear (a cross between a polar bear and grizzly), which has come into being because of global warming, and the killer bee, brought into existence because of the transfer of African bees to South America.

Finding the Way

Some animals have an extraordinary ability to find their way. The dung beetle, an insect revered by ancient Egyptians, uses the sun, the moon and even the Milky Way to move its prized ball of dung in the right direction. Pigeons are often considered feeble birdbrains, but they have incredible memories that can recall several complex travel routes with amazing accuracy and they even use man-made roads and hedgerows to find the quickest way home.

Extreme Babies

The giant panda gives birth to the smallest baby of any mammal and has to care for and protect it for many months. Why don't they give birth to more developed, robust young? The kiwi lays one of the largest eggs in the bird world, which produces a very well-developed chick. Why do kiwis produce a single egg that is a quarter of its body mass and almost too big to lay?

Curious Counters

Can animals count? This is a question that has intrigued and fooled investigators for a long time. Just over 100 years ago, a German horse called Hans was declared a mathematical genius but all was not as it seemed. And strangely, some bamboos around the world flower exactly at the same no matter where they are. Are they counting down the years?

Ferocious Fighters

The Siamese fighting fish is so aggressive it will fight its own reflection until it is exhausted. Recent research shows that the fighting behaviour varies and depends on the personality of the fish! Male kangaroos were once pitted against humans in the boxing ring, with the most impressive male kangaroos being solid blocks of muscle with a kick that can kill. Why do they fight and what skills must a winner have?

The Fruit Hunters: Evolution of Desire (Part 1 of 2)

A journey through nature, commerce and adventure, The Fruit Hunters takes us from the dawn of humanity to the cutting of edge of modern agriculture — a series that will change not just the way we look at what we eat, but what it means to be human. The Fruit Hunters' first episode, "The Evolution of Desire," explores the origins of fruit's diversity and tells the story of humanity and fruit's intimate co-evolution. Every variety of fruit has a story, the story of the person who cultivated an individual plant, and then shared something wonderful with the world. To preserve this diversity is to retain this living memory. A passionate few, the fruit hunters, fight to preserve this diversity in a world increasingly dominated by economically driven monoculture.

Friendship

The undercover cameras reveal how animals rely upon each other for a range of activities. Arctic wolves group together to survive in one of the harshest landscapes on earth, a band of hungry mongoose groom warthogs for tasty morsels - before turning their attention to Spy Warthog - and fish help clean hippos' bodies, as well as providing a unique dental service. Meanwhile, crocodiles and dikkop birds take part in a mutual neighbourhood watch against hungry prowling monitor lizards, and Spy Rattlesnake captures how prairie dogs and burrowing owls use their language skills to tell the rest of their community of approaching danger.

Compulsive Communicators

The final episode deals with the evolution of the most widespread and dominant species on Earth: humans. The story begins in Africa, where, some 10 million years ago, apes descended from the trees and ventured out into the open grasslands in search of food. They slowly adapted to the habitat and grew in size. Their acute sense of vision led to them standing erect to spot predators, leaving their hands free to bear weapons. In addition, the primitive apemen also had stones that were chipped into cutting tools. Slowly, they grew taller and more upright, and their stone implements became ever more elaborate.

David Attenborough’s Natural History Museum Alive

Britain's best-loved broadcaster brings his favourite extinct creatures back to life in David Attenborough's Natural History Museum Alive. In this ground-breaking film, Sir David takes us on a journey through the world-famous Natural History Museum in London in a captivating tale of discovery, adventure, and magic, where state-of-the-art CGI, science, and research combine to bring the museum's now long-extinct inhabitants to life to discover how these animals once roamed the planet. As the doors are locked and night falls, Attenborough stays behind and meets some of the most fascinating extinct creatures which come alive in front of his eyes; dinosaurs, ice age beasts, and giant reptiles. The film fulfils a lifelong dream of the nation's favourite naturalist, who said: "I have been coming to the Natural History Museum since I was a boy. It's one of the great places to come to learn about natural history. In this film we have the technology to bring back to life some of the most romantic and extraordinary extinct creatures that can be conceived; some are relatively recent animals like the dodo, others older like the dinosaurs, and some we only know through fossil evidence. Using our current scientific knowledge, this film brings these creatures alive, allowing me to look at some of the biggest questions surrounding them."

Animal Reunions

Animal Reunions have captured the imaginations of millions of people worldwide. YouTube is full of animal reunion stories - moments that illustrate and capture genuine affection and emotion between and among species. These rare moments provide a fleeting window into the emotional capacities of animals and their ability to form bonds with humans. But can wild animals really feel joy, devotion and love? Most animal lovers are convinced that they do, and now scientists are beginning to agree as we discover the stories that bring those animal emotions to life. We meet orphaned elephants in Kenya who have learned to trust their nursery keepers even after they lost their families at the hand of man - and witness a deep bond revealed as the head keeper travels to the National Park to see if his fully grown elephants remember him. We meet Damian Aspinall, the first man to release a captive-bred family of gorillas back to the wild, and see his reunion with one of those gorillas, proving a bond that may last a lifetime. We also meet Jane Goodall, the legendary chimpanzee researcher who was once heavily criticized for her claims about animal emotions; and Rebeca Atencia, the veterinarian who runs a Congolese chimp sanctuary set up by Goodall, as she travels to find the orphan chimpanzee she raised and released back into the wild. Through these incredible stories about human-animal relationships, illuminated by interviews with some of the world's most eminent ethologists and academics, this film sets out to question not only the emotional intelligence of animals but the so-called divide between us and them.
