The wild dogs of Luangwa Valley are organized, tenacious and strictly hierarchical under the leadership of an alpha pair. While cheetahs sprint and lions ambush, wild dogs rely on their stamina to wear prey out, sometimes running up to 20 miles at a time. But to maintain dominance, they'll need to train their youngest members to hunt effectively as part of the pack-and time is running out.
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.
After the Permian period, the epic saga of evolution and extinction on Earth produced the world's first dinosaurs, plesiosaurs and pterosaurs. They dominated land, sea and air until another period of extreme volcanism generated vast waves of lava and toxic gas and killed roughly 75% of all species.
A six-week-old lion cub gets separated from his pride and has to face the nighttime terrors of the African bush. Cub-hungry predators, dehydration, and rival lions instinctively primed to kill are just some of the threats ahead. Can this intrepid little misfit find his way back to safety, or will the harsh rules of the wild prevail?
Thanks to new technologies combining genetics, ethology, geology and even particle physics, paleontologists can now recreate the missing branches of the tree of life. Because of this, it has been discovered that prehistoric mammals were more varied and numerous than previously thought.
