Showing results for "the world" in Biological Sciences

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.

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.

Brown bears lead deeply cyclical lives. They need to gain sometimes hundreds of pounds during the warmer months to prepare for winter hibernation, a lifestyle that brings them into frequent contact with many other species’ cycles. In this episode, we meander through the Alaska peninsula with a bear and her cubs as she teaches them to hunt salmon at the falls, dig for clams along the coastal mudflats, and use the regional rubbing tree.

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

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.

Crows have long been the subject of folklore, likely because they’re strikingly similar to humans, leading lives rich in personality, intelligence, and relationships. In this episode, we fly the streets of Seattle with a crow as she grooms her mate, delivers what appears to be a gift, and finally commutes miles away from her territory to gather and chat with thousands of other crows before it’s time to roost for the night.

If you are at all interested in life on our planet, then you need to know about insects. They are the most successful group of animals ever to have lived on Earth. Making up three quarters of all animal species, insects conquered the planet long ago. They were among the very first animals to appear on land and were the first to take to the air. Their total biomass is at least 10 times that of all humans and our livestock combined.

Elephants are the largest land animals in the world. They are also intensely social and have advanced long-term memories. In this episode, a parade of Asian elephants makes its way through the Sri Lankan forest to a lake for drinks and mud baths, stopping periodically for group naps. The female leading the parade uses infrasonic rumbles—inaudible to humans, but traveling as far as two miles along the surface of the Earth as seismic waves—to invite friends and family around the forest to join her at the reservoir.

Every great drink starts with a plant. Sake began with a grain of rice. Scotch emerged from barley. Gin was born from a conifer shrub when medieval physicians boiled juniper berries with wine to treat stomach pain. The Drunken Botanist uncovers the surprising botanical history and fascinating science and chemistry of over 150 plants, flowers, trees, and fruits (and even a few fungi).

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.

A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century. In 2013, Lee Berger, a National Geographic explorer-in-residence, heard of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators - men and women small and adventurous enough to be able to squeeze through eight-inch tunnels to reach a sunless cave forty feet underground. It worked.

Dogs are a familiar and comforting part of many of our lives. In this episode, we take a walk with a pet xoloitzcuintli, or Mexican hairless dog, as he greets his blocks by smell. Along the way, we learn the backstory of squirrels in U.S. cities and observe the very smart and clean neighborhood raccoon.

In 1908, near Folsom, New Mexico, a cowboy discovered the remains of a herd of extinct giant bison. By examining flint points embedded in the bones, archeologists later determined that a band of humans had killed and butchered the animals 12,450 years ago. This discovery vastly expanded America's known human history but also revealed the long-standing danger Homo sapiens presented to the continent's evolutionary richness. Distinguished scholar Dan Flores's ambitious history chronicles the epoch in which humans and animals have coexisted in the "wild new world" of North America.

What if human cloning isn’t a modern discovery, but an ancient technology rediscovered? Long before modern science, civilisations like the Sumerians and the Anunnaki may have practiced genetic manipulation, creating humanity as engineered slaves for labour and obedience, not children of gods. Myths like Adam and Eve and divine bloodlines could be encoded records of this lost history. Occultists like John Dee weren’t just dabbling in magic, they sought to create life, continuing a hidden tradition of cloning.

In the tradition of Jared Diamond and Jacques Barzun, prize-winning historian Anthony Pagden presents a sweeping history of the long struggle between East and West, from the Greeks to the present day.

The relationship between East and West has always been one of turmoil. In this historical tour de force, a renowned historian leads us from the world of classical antiquity, through the Dark Ages, to the Crusades, Europe's resurgence, and the dominance of the Ottoman Empire, which almost shattered Europe entirely. Pagden travels from Napoleon in Egypt to Europe's carving up of the finally moribund Ottomans - creating the modern Middle East along the way - and on to the present struggles in Iraq.

What would it be like to visit the ancient landscapes of the past? To experience the Jurassic or Cambrian worlds, to wander among these other lands, as creatures extinct for millions of years roam? In this mesmerizing debut, award-winning palaeontologist Thomas Halliday gives us a breath-taking up-close encounter with worlds that are normally unimaginably distant.

A lifetime of adventures with bats around the world reveals why these special and imperiled creatures should be protected rather than feared.

Platypuses are mammals unlike any other on earth. They lay eggs, ooze milk through their skin, and can sense electricity. In this episode, we travel with a platypus as he moves through his nightly routine on the island of Tasmania. He uses electroreceptors to hunt underwater and does a synchronized swimming courtship ritual with his mate, who then digs a burrow 40 feet deep into the riverbank to nest.

Fennec foxes’ ears can be up to half as long as their bodies. They use them to track movement across the Sahara Desert, including under the sand. In this episode, we follow a fox as he meanders home to his family through the sand dunes as they slowly shift with the wind.

Sloths are the slowest mammals on earth. They can hardly see. They live in rainforests among jaguars, pumas, and countless other predators. Yet they survive. And they do it by being so incredibly slow, and living a life covered in algae. In this episode, we hang with a sloth in the jungle of Costa Rica as he spends a month digesting one single leaf, and we see the symbiosis and collaboration that surrounds him.
