About 340 million years ago a brand new family of animals was evolving in the primeval swamps. They were to go one step further than the amphibians who had emerged onto dry and before them. For they would eventually completely cut their ties with water. They were the ancestors of todays lizards. They evolved scaly impermeable skins and moved up into the forests. They diversified into a multitude of different shapes and sizes. They developed signalling systems to communicate with one another. And they squabbled as animals do. For food they hunted insects that were already well established on the land in great numbers. And here without returning to water they produced their families. They powered their bodies not only with food but with the heat that they drew directly from the sun.
As they diversified so they spread into the harshest of the lands habitats. The baking waterless deserts which eventually they would come to dominate. Discover jacky lizards that wave, wrestling beaded lizards and the the world's smallest chameleon, which is no bigger than his thumbnail, and the biggest lizard in Australia.
Richard Hammond explores the extraordinary wonders of the world of detail hidden in the blink of an eye. It takes our brain around a hundred and fifty milliseconds to process what we see. We're not aware of this time lag going on, but in those few milliseconds, there are extraordinary things happening that completely pass us by. But what if we could break through this speed limit? Bend and stretch time in ways never thought possible. What new marvels would we see? Now, using the latest high-speed cameras, Richard takes us on a journey beyond our eye's limits, letting us see secrets hidden in every element of our planet. A world where thin air can shatter rock. And water can tear through metal. A world where the fastest thing on earth lies right beneath our feet. And where a spectacular celestial display is finally captured, even though many have claimed it doesn't even exist.
In this episode, Helen seeks out the colours that turned planet Earth multicoloured. To investigate the essence of sunlight Helen travels to California to visit the largest solar telescope in the world. She discovers how the most vivid blue is formed from sulfur atoms deep within the Earth's crust and why the presence of red ochre is a key sign of life. In gold, she discovers why this most precious of metals shouldn't even exist on the surface of the planet and in white, Helen travels to one of the hottest places on Earth to explore the role salt and water played in shaping planet Earth.
An informative and ambitious journey exploring how the evolution of scientific understanding is intimately interwoven with society's historical path. The Story Of Science tells the forces that came together to create scientific knowledge; the practical business of making instruments and machines; the great forces of history – revolutions, voyages of discovery and artistic movements – and the dogged determination of scientists and experimenters. This is the story of how scientific ideas shaped the modern world and how science made history. Michael Mosley begins the first episode with the story of one of the great upheavals in human history - how we came to understand that our planet was not at the centre of everything in the cosmos, but just one of billions of bodies in a vast and expanding universe. He reveals the critical role of medieval astrologers in changing our view of the heavens, and the surprising connections to the upheavals of the Renaissance, the growth of coffee shops and Californian oil and railway barons. Michael shows how important the practical skills of craftsmen have been to this story and finds out how Galileo made his telescope to peer at the heavens and by doing so helped change our view of the universe forever.
Earth is the most colourful place we know of. But the colours we see are far more complex and fascinating than they appear. In this series, Dr Helen Czerski uncovers what colour is, how it works, and how it has written the story of our planet - from the colours that transformed a dull ball of rock into a vivid jewel to the colours that life has used to survive and thrive". But the story doesn't end there - there are also the colours that we can't see, the ones that lie beyond the rainbow. Each one has a fascinating story to tell. Early Earth was a canvas for the vast new palette of the colours of life, with the diversity of human skin tones telling the story of how humanity spread and ultimately conquered the planet. Dr Helen Czerski explores the true masters of colour - which are often the smallest and most elusive - travelling to the mountains of Tennessee to witness the colourful mating display of fireflies, and revealing the marine creatures that can change the colour of their skin in order to hide from the world.
The very heart of Africa is covered in dense tropical rainforest. The animals that live here find the most ingenious ways to carve out their space in a claustrophobic landscape. Danger lurks in every shadow, but some animals thrive here, from honey-stealing chimps to birds with a lineage as old as the dinosaurs, thundering elephants and kick-boxing frogs. Here in the Congo, no matter how tough the competition, you must stand up and fight for yourself and your patch.
As they diversified so they spread into the harshest of the lands habitats. The baking waterless deserts which eventually they would come to dominate. Discover jacky lizards that wave, wrestling beaded lizards and the the world's smallest chameleon, which is no bigger than his thumbnail, and the biggest lizard in Australia.
