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.
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.
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.
The single spiral tusk of the narwhal inspiration for tales of unicorns and the myriad variations on the twist of the snail shell have delighted and fascinated naturalists and artists since the dawn of civilization.
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.
Sir David Attenborough uses this episode to investigate two animals who are capable of true virgin birth - the production of offspring without the need for sex.
This episode explores the story of two animals that hide behind seemingly impregnable coat of arms. Can Sir David Attenborough get in behind their armour and reveal their mysteries?
Here we discover that some animals are able to trick others into believing they are something that they are not. The art of deception is a powerful attribute for some.
After initially gaining frightening reputations, it's now known that gorillas and bats are a lot gentler and considerate than their early reputations suggest.
Plants and animals have some curious super senses that enable them to see, hear and feel things that are quite invisible to us.
In this episode we explore the remarkable adaptations of two creatures that have evolved to survive the most challenging of conditions and seem to defy the laws of nature.
We'll find out how nature is incredibly inventive and has produced two unique mechanisms of natural construction that have fascinated scientists for centuries; weaving in birds and silk.
"Strange Parents" asks how we usually recognise animals as either male or female and how each sex normally plays a particular role in their own life cycle. However both hyenas and seahorses completely break the gender rules.
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.

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.

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.

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?

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?

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?

Located on the Malilangwe Game Reserve in southern Zimbabwe, this 800-year-old baobab is a remarkable tree containing its own ecosystem. Capable of withstanding extreme drought by storing water in its hollow trunk, it draws a multitude of wildlife, from elephants who strip its bark in search of food, to vultures that nest on its branches. Remarkably, it also has another gift: a velvety fruit packed with an astonishing cocktail of nutrients. To witness the baobab is to be awed by the natural forces that produced it.

The third episode looks at the last generation of killer dinosaurs - carnivores that took killing to a new level. By the end of the cretaceous period - 75 millions years ago - these gigantic and specialised hunter-killers had spread throughout the globe. In the southern continents it was the powerful and muscular abelisaurids that reigned supreme but it was the famous tyrannosaurids (or tyrant dinosaurs) that dominated in the north. Whilst the northern daspletosaurus hunted in gangs, using its highly developed smell and hearing to take down opponents like the horned rhino-sized beast, chasmosaurus, in the Southern hemisphere the small-skulled majungasaurus reigned. And though the sharp toothed majungasaurus was an efficient killer of the much smaller feathered rahonavis that did not stop it from occasionally turning cannibal and hunting its own.
