Professor Alice Roberts meets our ancient ancestral family, from armadillos to sharks, and discovers our true place in the tree of life. With 4D scanning, giant origami and a ukulele, they will explore evolution like never before.
Forty miles north of Honduras, near the Bay Island of Roatan, is a spectacular and pristinely preserved coral atoll: the Mesoamerican Reef. Explore the abundant and diverse marine life, lush vegetation, and magnificent caves of this rare underwater wonder.
In this episode Brian uncovers how the stunning diversity of shapes in the natural world are shadows of the rules that govern the universe. In Spain he shows how an attempt by hundreds of people to build the highest human tower reveals the force that shapes our planet. In Nepal, honey hunters seek out giant beehives that cling to cliff walls. The perfect hexagonal honeycombs made by the bees to store their honey conceal a mathematical rule. Off the coast of Canada, Brian explains how some of the most irregular, dangerous shapes in nature - massive icebergs that surge down from Greenland and into shipping lanes of the Atlantic - emerge from a powerful yet infinitely small force of nature. Even the most delicate six-sided snowflake tells a story of the forces of nature that forged it.
Take a trip through the spectacularly diverse terrain of the Waterberg--a South African land so old it was formed before terrestrial life itself. Today, its sprawling grasslands are home to some of the most eclectic wildlife on Earth, all sustained by the region's abundant water supply.
In many of the earth's natural wonders there is an abundance of animals. These can be a devastating threat to the people who live there, or they can provide a means of survival, but often at a high price. In the coastal salt marshes of northern Australia's Arnhem Land, Indigenous Australians still go hunting for the eggs of one of the world's most aggressive predators - the saltwater crocodile. Vanuatu is an island paradise in the south Pacific, but life here isn't perhaps as idyllic as it appears. Overfishing has reduced fish stocks, making food harder to come by for the indigenous islanders like 45-year-old Nigasau.
