David Attenborough reveals that the animal inhabitants of this vast wilderness are every bit as extraordinary as they are bizarre. Unearthly calls of the notorious Tasmanian devil echo through the land, but following them over the course of a year reveals a surprisingly gentle side. In the dry east, rare white wallabies graze on the plains and jack jumper ants build huge nests – these venomous ants are amongst the most dangerous on earth. In the west, where it can rain nearly every day of the year, caves light up with the magical spectacle of thousands of glow-worms, and the trees are 100-metre towering monsters. Rivers are home to the peculiar platypus, and world’s largest freshwater invertebrate, the Tasmanian giant lobster. Miniature penguins come ashore to breed, and as winter approaches, the southern lights dance in the sky. Tasmania’s isolation and unique climate has created a world that is as weird as it is wonderful.
In the final episode of this groundbreaking scientific study, Liz Bonnin and a team of scientists reveal the secret language of our cats, the surprising conversations they have when we are asleep, and why they meow to us but not each other. We rig a house with cameras and cat trackers to discover if four cats living under one roof all get on as well as we would like to think. And we find out why living alongside us is making life difficult for our 21st-century cats.
Captured in a single, animated time lapsed shot, and based on archeological findings, we trace our epic journey from the first spark of life billions of years ago up to our present status as the most successful species on the planet. Humans are the pinnacle of a chain of species that has survived by way of evolution, natural selection, adaptation, and pure luck. From the formation of primordial genetic material to the development of speech, this is the improbable story of the incredible set of circumstances that led to human existence.
Steve Backshall reveals the incredible influence that insects and their close relatives have on Earth's many ecosystems. In the grasslands of South America the landscape has been created almost solely by one team of insects - grass-cutter ants. Across the world's oceans one tiny creature plays such a key role that, without it, the largest animal on our planet, the blue whale, could not exist. And in East Africa the savannah would quickly be swamped in dung were it not for the activities of a certain beetle. Yet the greatest influence of all comes from a group of insects that have ultimately changed the colour and diversity of our planet.
