More than a billion people around the world commute into cities each day, and they are not alone. The world's wildlife is commuting too. A steady flow of animals journey in and out of cities to find food and shelter or to start a family. Leaving the wilderness they must overcome the unique challenges that the urban world throws at them to benefit from the opportunities on offer. This episode explores whether the secret to an animal's success in this fast-changing world is to keep one foot in the wild and one in the city, becoming a wild commuter. It seems that all over the world animals are finding that the city can offer opportunities that are harder to come by in the natural world. Some, like African penguins, whose population has plummeted by 80 per cent in the last 50 years, find shelter in the city. By nesting in Cape Town they are safer from predators, and with relatively easy access to their fishing grounds they have the best of both worlds. Many other animals commute into cities because they are filled with food. In St Lucia, South Africa, that includes hippos. Able to eat up to fifty kilograms of grass in a single sitting, they have developed a taste for the short, manicured lawns and come to town every night to dine out. St Lucia's human residents have learnt to give the hippos the space they need during their night-time raids. Black bears need to eat more than 20,000 calories a day to survive their six-month hibernation through winter, and using their acute sense of smell they can easily track down leftovers. In North America they come into towns and cities in search of food. Many animals displaced from their natural habitat are now using their wild skill set in the city to help fulfill their needs. Could this be the beginning of a new and very modern migration?
The story of how more than 220 dinosaur bones were found in the Argentinean desert, which were found to have come from a previously undiscovered species, which is the largest land dwelling animal known to have existed. David Attenborough visits the archaeological dig and a laboratory where the remains are being cleaned and analysed with lead scientist Dr Diego Pol and evolutionary biologist Ben Garrod, and meets animators, model-makers, paleontologists and anatomy experts who are working to reconstruct what the 37 metre-long creature would have looked like.

The NHK team that captured the world's first footage of a live giant squid in its natural habitat is setting out for another deep-sea adventure. They will give us a look at the amazing life forms with luminous bodies that have survived the harsh, pitch-dark deep sea environment of the Pacific.
The savannah is home to some of the greatest herds on Earth, and in this episode, Wild Africa brings you close encounters with these animals. The savannah is Africa's youngest landscape, shaped by the weather and the animals themselves as the continent dried. It is now home to baboons, wildebeest, lions, cheetah, and aardvarks who must struggle through the eight-month dry season to survive.
Cheetahs are not your standard big cats, they differ from the others in many ways. First, cheetahs are daytime hunters with eyesight optimized for open landscape and distant prey. Second, They're possibly the fastest land animals that have ever lived.
This instalment examines the earliest land vegetation and insects. The first plants, being devoid of stems, mainly comprised mosses and liverworts. Using both sexual and asexual methods of reproduction, they proliferated. Descended from segmented sea creatures, millipedes were among the first to take advantage of such a habitat and were quickly followed by other species. Without water to carry eggs, bodily contact between the sexes was now necessary. This was problematical for some hunters, such as spiders and scorpions, who developed courtship rituals to ensure that the female didn't eat the male.
