Evolve - Die Zukunft ist tierischStaffel 1
TV-PG
The world is full of fascinating animals which come in a multitude of species. But how did these species evolve? What features do they have that makes them different? This series investigates different anatomical features which animals have evolved over millions of years.

- Eyes
F1EyesThey are one of evolution's most useful and prevalent inventions. Ninety five percent of living species are equipped with eyes and they exist in many different forms. Learn how the ancestors of jellyfish may have been the first to evolve light-sensitive cells. Discover how dinosaur's evolved eyes that helped them become successful hunters. Finally, learn how primates evolved unique adaptations to their eyes that allowed them to better exploit their new habitat, and how the ability to see colours helped them find food. - Verdauung
F2VerdauungDiese Folge beschäftigt sich mit der Rolle eines elementaren Organsystems, das die Entwicklung einiger der erfolgreichsten Lebewesen dieser Erde maßgeblich mitbestimmt hat: der Verdauungsapparat. In einer atemberaubenden Reise durch die Geschichte der Evolution wird die Bedeutung der Verdauung aufgezeigt, die bereits vor 575 Millionen Jahren das Leben der ersten mehrzelligen Organismen prägte. Hochauflösende Computergrafik und fesselnde Bildaufnahmen verwandeln diese Sendung in eine einzigartige Dokumentation über den Kampf ums Überleben und das Wunder der Evolution. - Jaws
F3JawsIt's one of the most important developments in the history of life. An adaptation that lets animals kill, butcher, and devour. There is perhaps no instrument more important to survival than a strong set of jaws. From the shark's rows of razor-sharp serrated teeth, the crocodile's overwhelmingly swift-snapping-trap, to the lion's shredding canines--all have evolved in response to the never-ending struggle between predator and prey. But just how did these ultimate killing weapons develop in the first place? - Sex
F4SexIn the history of life on earth, sex may be the ultimate survival skill, because the bottom line is: reproduce or die. This episode looks at sex in its many forms, from sharks--among the first vertebrates to have intercourse--to dinosaurs that had to figure out how to join their giant bodies together to mate; from the stick insect (that mates non-stop for 10 straight weeks) to macaques monkeys (about once an hour)... and finally to humans. This driving force of life comes in many forms. How will sex evolve in the future? Are we evolving beyond sex? In fact, is a time coming when we will be able to seize control of our own evolution... not via sex at all, but through genetic engineering? - Skin
F5SkinIt makes up 16% of your body weight, is the largest organ in the human body, allows birds to fly, mammals to nurse their young, and provides a lifelong defence against predators and parasites alike. What is it? Skin. From the delicate membranes that encased the earliest animals to the leathery hides that protected the dinosaurs, this episode looks at how skin has changed and adapted to virtually any challenge it has faced throughout history. - Flight
F6FlightHumans have always been fascinated with the one part of the world that we could not conquer - the sky. How did the earth's first flying creatures come to be? In this episode of Evolve we will examine the first vertebrate flyer, the pterosaur, which took to the air over 220 million years ago and eventually evolved to be the size of small airplanes. Scientists have long pondered how they, the largest flying creatures ever, were able to achieve such an astonishing feat. Scientists examine the fossil record and living birds to try and unlock how some species evolved to have the remarkable trait of flight. - Communication
F7CommunicationHow has our ability to communicate defined us as a species? Sharing information with each other has allowed humans to rise to the top of the food chain and dominate our environments. But humans aren't the only species that can communicate. Organisms as simple as bacteria can communicate, a strategy that lets them cooperate to take down creatures millions of times their own size. Fish use pheromones to warn each other about predators and find mates. Chemicals are also an effective means of communicating on land, and they've allowed insects--some of nature's smallest and most unassuming animals--to become the most populous and prolific on earth. The ability to interact stretches back billions of years and has often been one of the primary factors in a species ability to evolve and survive. - Gift
F8GiftGift ist die gefährlichste Waffe, die einigen Lebewesen zur Verteidigung und zum Angriff im Laufe der Evolution von der Natur mit auf den Weg gegeben wurde. Quallen, Insekten, Schlangen und sogar Säugetiere wie zum Beispiel das Schnabeltier setzen Gift ein. HISTORY sprach weltweit mit Wissenschaftlern, die erläutern, wie die Entwicklung von Giftstoffen manchen Kreaturen bessere Überlebenschancen ermöglichte. Eines dieser Lebewesen ist der australische Inland Taipan, die giftigste Schlange der Welt. Sie injiziert nach mehreren Bissen ihr selbst für Menschen absolut tödliches Serum. Neben dieser Schlange gibt es allerdings ein noch giftigeres Tier, die im Meer lebende Kegelschnecke. All diese Tiere haben ihre Giftstoffe in ihrer evolutionären Laufbahn optimiert, wodurch sie im natürlichen Kampf ihren Opfern überlegen sind. - Venom
F9VenomThe deadliest natural weapon employed in the animal kingdom, venom has independently evolved in creatures as diverse as jellyfish, insects, snakes, and even mammals. Scientists from around the globe show how evolution adapted venom to fit the needs of the animals who wield it. Injecting venom into samples of his blood, Australia's Bryan Fry demonstrates how the world's deadliest snake, the inland taipan, has converted the building blocks of its body into lethal toxins. Toto Olivera will introduce us to the cone snail, pound-for-pound the most toxic creature in the world, able to continually update its chemical cocktails with the help of the world's fastest-evolving genes, guaranteeing the creatures stay one step ahead of their prey. - Shape
F10ShapeLiving organisms have entered into a battle for survival for hundreds of millions of years and the pressure to survive has resulted in ever changing shapes. From the hammerhead shark to the platypus, new and sometimes extreme shapes can mean survival for certain species. But, as nature has proven, sometimes the most basic shapes on earth have the staying power of survival. This episode will explore the evolution of animal shape and how the slightest alteration of a leg or a head can mean the difference between life and extinction. - Speed
F11SpeedThe ability to react and move can often mean the difference between life and death in the animal kingdom. Some animals have evolved into championship fliers, swimmers, and runners. What are the forces that create this need for speed, and how do animal bodies adapt to go into overdrive? In this episode, find out about nature's ultimate engine, muscle, how it evolved and how it works. Meet some of the fastest species on earth.
