In Tokyo, there are unapproachable "lost islands" where unspoiled environs cradle rich wildlife. Sofugan is a 100-meter-high solitary rock pillar standing in the ocean 650km south of the capital city's center. Remote and difficult to access, it had never been explored in detail. A group of scientists and engineers set out on a two-year survey. This program records their journey, along with the creatures they discover - from unusual species amongst the rugged rocks to mysterious marine life in the surrounding deep sea.
The human eye is an amazing mechanism, able to detect anywhere from a few photons to a few quadrillion, or switch focus from the screen in front of you to the distant horizon in a third of a second. How did these complex structures evolve? Joshua Harvey details the 500 million year story of the human eye.
Plants' solutions to life's challenges are as ingenious and manipulative as any animal's. Innovative time-lapse photography opens up a parallel world where plants act like fly-paper, or spring-loaded traps, to catch insects. Vines develop suckers and claws to haul themselves into the rainforest canopy. Every peculiar shape proves to have a clever purpose. The dragon's blood tree is like an upturned umbrella to capture mist and shade its roots. The seed of a Bornean tree has wings so aerodynamic they inspired the design of early gliders. The barrel-shaped desert rose is full of water. The heliconia plant even enslaves a humming bird and turns it into an addict for its nectar.
The fifth programme explores the alliances formed between the animal and plant worlds. It examines the ways in which plants live together and rely on each other. Whether living together in harmony, relying on each other for homes, protection or food, or living off each other, by strangling or otherwise destroying each other in a bid to survive.
