Formed from the remains of a 2.5 million-year-old imploded volcano, the Ngorongoro crater is a study in contradictions: On one hand, it's a self-sustained and plentiful land that provides for the many animals that call it home. Conversely, its isolation threatens the existence of many of its key species. What does the future hold for this unique habitat?
David Attenborough has a passion for birds' eggs. These remarkable structures nurture new life, protecting it from the outside world at the same time as allowing it to breathe. They are strong enough to withstand the full weight of an incubating parent and weak enough to allow a chick to break free. But how is an egg made? Why are they the shape they are? And perhaps most importantly, why lay an egg at all? Piece by piece, from creation to hatching, David reveals the wonder behind these miracles of nature.
Formed during a cataclysmic volcanic eruption two million years ago, Tanzania's Ngorongoro Crater is home to the highest concentration of mammals in the world. Explore this vibrant ecosystem and the extraordinary geological features that have made it a haven for biodiversity.
Planet Earth was inhabited by many wondrous creatures throughout the Permian period. Massive geologic changes finally allowed life to thrive on land and sea, producing voracious saber-toothed carnivores like Gorgonopsid and the terrifying 40-foot shark Helicoprion. But it couldn't last forever...
