The show takes a spooky turn as we go on a ghost hunt through the natural world. Sebastian shares his adventures finding fossils – the traces of animals that once lived, and Rutendo talks about her experiences in The Cradle of Humankind, the South African UNESCO World Heritage site containing early human fossils. Deep in the Peruvian Amazon there is a species of wild dog so rarely sighted it has become known as the ‘ghost dog’. We hear from Renata Leite Pitman, one of the few scientists to...

The difference between order and chaos can depend on your perspective. The systems and processes that drive the natural world might seem random in close-up, whether it’s an ant wandering around near its nest, or a wildebeest charging through the water. But if you zoom out, you can see how these small activities combine to form part of a bigger picture. The Darwin Tree Of Life project is an attempt to bring order to nature by sequencing the DNA of every living thing in the UK, a staggering...

Sebastian is not afraid to admit that he lacks natural rhythm. But Rutendo thinks he’s too hard on himself – perhaps the world is just out of sync with him. Besides, every living thing is built upon natural rhythms, from our response to night and day, to the beating of our hearts. Kristina Bolinder leads us on an exploration of a plant with a very unusual habit: it only flowers under the light of the full moon. The reason why connects a century of lunar records with the latest in botanical...

In an age of individualism, sometimes we are more connected than we think. And the same is true for everything on the planet. Rutendo and Sebastian explore the question of how and why we define an individual, a colony, or a group, across the animal kingdom. Lisa Kirkendale was astounded when she came across the longest organism ever discovered, a siphonophore off the coast of Australia. Composed of several semi-independent but constantly connected parts known as zooids, could it be seen as a...

It’s a scary world out there, as we explore how everything on the planet – from humankind to glaciers – must be able to respond to threat in order to survive. Sebastian surprises Rutendo with a story of the time he lived in Japan and took up fencing, occasionally finding himself at the wrong end of a sword. WWE wrestler and commentator Stu Bennett, better known as Bad News Barrett, is used to feeling the pressure in the ring. But away from that controlled environment, he has faced less...

Light and reflection are crucial across the animal kingdom, and sometimes they interact in strange and surprising ways. Rutendo tells Sebastian about the time she carried out a classic experiment, the mirror test, with lions, during her PhD. Some lions made friends with the mirrors, while others pursued less wholesome activities... The hatchet fish has evolved a fascinating means of hiding itself from predators, especially those searching out their prey with giant bioluminescent headlights....

Sebastian and Rutendo celebrate nature’s defenders in all their forms. They argue that vultures should get more credit for their vital role as scavengers. Their super-acidic stomachs kill off deadly bacteria, like anthrax, that accumulates onrotting carcasses. This prevents the spread of disease and recycles nutrients back into the environment. Molecular biologist Mike Kolomiets tells us that the fragrance of newly mown grass isactually a scream for help and a warning to nearby plants that a...

Rutendo and Sebastian are looking at stories and whether it matters who is telling them. Paula Kahumbu is a renowned conservationist and film-maker in Kenya who wants to see more African stories told by Africans for Africans. “It's really important that Iam empowered to tell my own story. Not just that it's authentic, which therefore will resonate with the audiences ...but also it boosts my ability to have more impact out there.” Through her programme: ‘Wildlife Warriors’, Paula is training,...

We explore the invisible pulling powers of nature through the forces of smell, sound and gravity. In Greece, desert ants start their lives underground in total darkness. Void of landmarks and sun they initially learn to orient themselves using the Earth’s magnetic field. German scientist Dr Pauline Fleischman reveals how her team discovered the ant’s internal GPS. A healthy coral reef is a very noisy place, full of the snapping, rasping, scraping and croaking of various vocal species. But a...

Rutendo and Sebastian explore death and its role in the natural world. For Sebastian, death is a permanent state, a complete end to a life. But for Rutendo and her family, death is just a temporary parting. Around the world burial customs differ, but throughout nature, death and decay provide sustenance to other life-forms.   Sebastian explores the extraordinary diversity within the ground, with soil ecologist Frank Ashwood, who explains that a single teaspoon of healthy soil contains more...

Rutendo and Sebastian get to indulge their passions for nature AND superheroes, as they look at real-life superpowers in nature. Rutendo explores how these superpowers inspire fictional worlds and heroes with Mike McHargue, a science advisor/world builder for film and television. Mike helps writers and film-makers integrate accurate and consistent science into their stories, and together he and Rutendo invent a brand new superhero. Rats seem unlikely superheroes but in Tanzania they’re being...

You don’t need to be on an African Savanna to enjoy a safari. Rutendo and Sebastian explore how to have a nature adventure wherever you are.   On the isle of Bute in Scotland, Nature Instagrammer Lucy Lapwing takes us on an immersive walk through her local woodland. It’s a wonderfully damp, fresh day, and the forest is dripping with lichen and bright lime green moss as Lucy points out local birds and wildlife.  Rutendo and Sebastian go in search of spiders in Bristol, and with the ingenious...

In the final episode of series 4, we’re digging into some of the more elusive corners of our planet. To begin, we’re on a bear hunt deep in the Bornean rainforest. Guiding us is Siew Te Wong, who is the world’s foremost authority on a bear we know very little about. The sun bear is the smallest bear in the world and, as Wong has discovered for himself, tracking them can draw up some unexpected discoveries. Next we’re turning our attention upwards, to the sky at night. Or, to be more...

In this episode, we’re delving into the topic of extinction. We'll be finding out about some of the animals who are critically endangered, meeting the people trying to rescue them, and exploring species who may be able to make miraculous comebacks. Perhaps one of the most endangered species is the vaquita, a small sea mammal with a population of less than 20. We hear from some extraordinary people weathering threats and tragedies in an attempt to bring these ‘pandas of the ocean’ back from...

In this episode, we’re displaying the most impressive artists of the animal kingdom. From tiny visual masterpieces, to animals that can dance to a beat, we’re shining a spotlight on the art that can be found in nature. Deep in the Amazon rainforest, there’s a tiny structure that (if you’re able to spot it) catches your eye. The intricate silk henge is a mini masterpiece, and for some time nobody could say exactly what it was or why it existed. Phil Torres takes us on his journey of...

While nature is full of beauty and wonder, it also has a deadly side. In this episode, we're getting a brush with death and exploring how nature can be both a source of comfort and a source of danger. Prosanta Chakrabarty spends his time studying different species of fish in some of the world's most hostile spots. He leads us into a deep, dark cave in Madagascar where he and his team didn't just discover a new species, but also discovered a new illness. We’ll be introduced to the unlikely...

We’re exploring the parts of our world that require us to look a little deeper. From the depths of our oceans to the canopies that grace our skylines, we’ll be venturing into unfamiliar pockets of nature with the people who have carved a life out of choosing to study the things that many of us can’t see. First up, we meet Matthew Doogue who finds solace in capturing small things. He tells us how photographing the tiniest creatures has helped him find a greater sense of happiness. We also...

We’re exploring the boundary between our world and the world of myth, mysticism, and magic. We’ll discover how some of the customs and practices from our ancient ancestors continue to influence our relationship with the natural world today. To begin, we’re opening our ears to some of the sounds of the natural world and the inanimate objects that produce them. On a trip to Serengeti, Jahawi stumbled across rocks which, when hit by another type of rock, produced different sounds. He leads us...

There are few places on our planet that have not in some way been shaped by humans. We’re looking at how, for better or worse, we’ve made a mark on our world, and whether it’s possible to escape the influence of us. To begin, we travel to Aldabra - an idyllic coral atoll in the Indian ocean. It’s one of the most remote places in the world, home to giant tortoises and very little human intrusion. Yet even in this largely uninhabited spot, traces of humanity can be found. Next we’ll be...

We’re exploring the theme of recovery, delving into times when we’ve stepped in to help save our natural world, and looking at the moments when it’s come to our rescue too.   We’ll be starting off in the sea off the West Coast of Africa where a crew member from the latest David Attenborough series, A Perfect Planet, will take us behind the scenes on an eye-opening rescue mission.   We’ll then meet the Bloom family, whose lives were turned around following a life-changing accident. The road to...

In this week’s episode of the BBC Earth podcast we’ll be looking to solve some of the natural world’s mysteries. Starting off in North West Honduras, we’ll hear from ethnobiologist and sound artist Ben Mirin who set out to discover the voice of a previously voiceless animal. The exquisite spike-thumb frog is a critically endangered species. Recording its voice could help save this frog. The only problem is, nobody actually knows what it sounds like. We’ll also be taken on a personal...

We're exploring what the natural world can teach us about teamwork. We'll learn how in some of the most remote locations and harshest conditions, strength can come in numbers. In the Amazon rainforests in Northern Peru, tiny creatures have found an ingenious way to tackle the annual floods. With the help of a crew member from the landmark series, A Perfect Planet, we'll be floating alongside fire ants forming a living raft. Tens of thousands of penguins make the journey from the sea to a...

We're journeying into hidden worlds, exploring nature that offers much more than what initially meets the eye. We travel to locations that continue to thrive against the odds. When Long Litt Woon's life drastically changed, she turned to the secretive world of mushrooms to manage her grief. She tells us how these visible fungi are just one tiny part of a vast and complex organism that lives beneath our feet. We'll hear how a crew member filming the latest David Attenborough series, A...
