Sharks are among the most misunderstood predators on the planet, but an international team of scientists is trying to change that. Their research is revealing that sharks can be sociable and intelligent, and they could even help solve some of the toughest medical challenges of the 21st century. However, their breakthroughs come just as many sharks face extinction. Science may now be the only way to save them.

Liz Bonnin presents a controversial and provocative episode of Horizon, investigating how new scientific research is raising hard questions about zoos - the film explores how and why zoos keep animals, and whether they need to change to keep up with modern science, or ultimately be consigned to history. Should zoos cull their animals to manage populations? Liz travels to Copenhagen Zoo, who killed a giraffe and fed it to the lions, to witness their culling process first hand. They think it is a natural part of zoo keeping that is often swept under the carpet. Should some animals never be kept in captivity? In a world exclusive, Liz visits SeaWorld in Florida and asks if captivity drove one of their orcas to kill his trainer. But could zoos be the answer to conserving endangered species? Liz examines their record, from helping breed pandas for the wild to efforts to save the rhinos. She meets one of the last surviving northern white rhinos and discovers the future of this species now lies in a multimillion-dollar programme to engineer them for stem cells. Veteran conservation scientist Dr Sarah Bexell tells Liz the science of captive breeding is giving humanity false hope.

As the Ganges nears the sea, it joins its mightiest tributary the Brahmaputra, creating a vast flood-prone delta. Here the bustling cities of Calcutta and Dhaka meet the wetlands, home to giant lizards and snakes, huge mean-eating crocodiles and forests full of monkeys. This is a story of human life persisting in wildly variable conditions in a domain that is still the preserve of the royal Bengal tiger.

We can all trace our lives back to a beginning. But what defines the beginning? Is it the moment when two cells unite? Or does something have to know it is alive before its life can begin?
