We humans like to think of ourselves as highly evolved creatures. But if we are supposedly evolution's greatest creation, why do we have such bad knees? Why do we catch head colds so often - 200 times more often than a dog does? How come our wrists have so many useless bones? And are we really supposed to swallow and breathe through the same narrow tube? Surely there's been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last.

Now settled into the sleepy Yorkshire village of Darrowby, and married to Helen the farmer’s daughter, James Herriot thinks he’s finally got himself sorted. But life as a vet in the 1930s was never going to be easy. Quite aside from his unpredictable colleagues, brothers Siegfried and Tristan Farnon, he must contend with new fangled medical techniques, delivering calves after far too much home-made wine, and a grudge holding dog called Magnus who never forgets. And then, with Britain on the verge of war, James faces a decision that could separate him from Darrowby – and Helen – for ever....

Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in 21st century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why its absence is so damaging to our health. Compared to the other basic drives in life - eating, drinking and reproducing - the purpose of sleep remained elusive.

Oxygen takes the listener on an enthralling journey, as gripping as a thriller, as it unravels the unexpected ways in which oxygen spurred the evolution of life and death.

Covering a year’s worth of introductory general chemistry at the college level, plus intriguing topics that are rarely discussed in the classroom, this amazingly comprehensive course requires nothing more advanced than high-school math. Your guide is Professor Ron B. Davis, Jr., a research chemist and award-winning teacher at Georgetown University.

From the plains of ancient Mesopotamia to the rolling hills of medieval England to the vast sheep farms of modern-day Australia, sheep have been central to the human story. Starting with our Neolithic ancestors' first forays into sheep-rearing nearly 10,000 years ago, these remarkable animals have fed us, clothed us, changed our diet and languages, helped us to win wars, decorated our homes and financed the conquest of large swathes of the earth.

One of the nation's most popular presenters, Sir David examines 40 marvels of the natural world from his extraordinary and pioneering experiences. What was Sir David's first pet? Which animal would he most like to be? How did he track down a giant earthworm? Why does he respect rats? And what did he do when confronted by a 10-foot-long reptile? His enthusiasm is as infectious as ever and conveys a unique fascination on topics as diverse as the sloth, monstrous flowers, the platypus, dragons, the fire salamander, the coelacanth, the dodo, bird's-nest soup and the large blue butterfly.

Over the past 20 years, Evolutionary Biologist Herman Pontzer has conducted ground-breaking studies across a range of settings, including pioneering fieldwork with Hadza hunter-gatherers in northern Tanzania. This book draws on his eye-opening research to show how, contrary to received wisdom, exercise does not increase our metabolism. Instead, we burn calories within a very narrow range: nearly 3,000 calories per day, no matter our activity level.

I hate every wave of the ocean', the seasick Charles Darwin wrote to his family during his five-year voyage on the H.M.S. Beagle. It was this world-wide journey, however, that launched the scientists career.

In each episode, we bring you riveting interviews with individuals who have had encounters with the elusive Sasquatch. Each one of these stories will leave you wanting more. But that's not all. We go beyond the encounters and explore the realm of Bigfoot research from a critical thinking perspective. We bring you interviews with field researchers who dedicate their lives to unraveling the mysteries surrounding Sasquatch. These dedicated individuals use hard science and rigorous methodologies to investigate the existence of this legendary creature. Through thought-provoking discussions, we aim ...

This is the third and last of Sir David’s great natural history books based on his TV series and completes his survey of the animal world that began with Life on Earth and continues with Living Planet. In Life on Earth, Sir David showed how each group of animals evolved. In Living Planet he looked at the way they have adapted to the whole range of habitats in which they live. Now, in Trials of Life, he completes the story by revealing how animals behave – and why.

Mother deer that grieve? Horses that feel shame? Squirrels that adopt their grandchildren? We humans tend to assume that we are the only living things able to experience feelings intensely and consciously. But have you ever wondered what's going on in an animal's head? From the leafy forest floor to the inside of a beehive, The Inner Life of Animals takes us from microscopic levels of observation to the big philosophical, ethical and scientific questions.

Humpback whales are among the most intelligent animals on Earth. Some scientists believe they might even surpass humans in self-awareness, empathy, and communication skills. In this episode, we swim with a whale as he teams up with other humpbacks to use bubbles to catch fish, rescues a sea lion, and puts his own spin on melodies sung by whales across the Pacific Ocean. This is the world in its natural state, defined by seasons, routines, and cycles. By the time this whale is ready to close one eye and go to sleep, you will be too.

An Immense World will take us on an insider's tour of the natural world by describing the biology, physics and chemistry animals use to perceive it. We may lack some of their senses, but our own super-sense lies in our ability to understand theirs. And in the face of the largest extinction event since the meteor that killed the dinosaurs, our only hope of saving other species is bound up with our ability to see what they see, and feel what they feel.

Whether you live in a mountain cabin or a city loft, plant spirits present themselves to us everywhere. Since its first edition in 1995, Plant Spirit Medicine has passed among countless audiences drawn to indigenous spirituality and all things alive and green. In this updated edition, Eliot Cowan invites us to discover the healing power of plants - not merely their physical medicinal properties, but the deeper wisdom and gifts that they offer.

This is a story about you. It is the history of who you are and how you came to be. It is unique to you, as it is for every one of the 100 billion modern humans who has ever drawn breath. But it is also our collective story, because in each of our genomes we carry the history of the whole of our species.

“I love food” Nakkiah Lui says, and in the next breath whispers “so give us back our land”. In First Eat, a confrontational, raw and highly personal exploration of food politics, power and body sovereignty, Nakkiah Lui asks how our meals would look different if First Nations people owned the land from which the food came. First Eat is about more than just food, it’s an aural feast for a rich future.

We human beings share 98 percent of our genes with chimpanzees. Yet humans are the dominant species on the planet - having founded civilizations and religions, developed intricate and diverse forms of communication, learned science, built cities, and created breathtaking works of art - while chimps remain animals concerned primarily with the basic necessities of survival. What is it about that two percent difference in DNA that has created such a divergence between evolutionary cousins?

In one of the great ironies of the modern world, the science that was expected to solve life’s mysteries has done just the opposite. New discoveries have led to more unanswered questions, created deeper mysteries, and brought us to the brink of forbidden territory when it comes to explaining our origin and existence. New York Times best-selling author and 2018 Templeton Award nominee Gregg Braden crosses the traditional boundaries of science and spirituality to answer the timeless question at the core of our existence.

When we talk about human history, we focus on great leaders, mass migration and decisive wars. But how has the Earth itself determined our destiny? How has our planet made us? As a species we are shaped by our environment. Geological forces drove our evolution in East Africa; mountainous terrain led to the development of democracy in Greece; and today voting behaviour in the United States follows the bed of an ancient sea. The human story is the story of these forces, from plate tectonics and climate change, to atmospheric circulation and ocean currents.
