Going down into these narrow flooded passageways is not for the faint-hearted but, with only an estimated one percent of the caves explored, it is an opportunity for the team to write themselves into cave diving history, by pushing further in than anyone has before. This is a challenge that tests even the most accomplished cave divers. Steve must face the terrors of being lost in an underwater silt cloud in a cave. But there is a bigger issue at stake. All life in the Yucatan depends on the fresh water in this network of caves, but it's being contaminated by human development. With every metre the team maps, it adds to the knowledge of the system, which, in turns, helps protect it for future generations.

For the last decade, a team of frontline medics has been fighting to save Borneo's critically endangered orangutans. Armed with cameras, International Animal Rescue has documented their struggle: pulling apes from devastated jungle, giving emergency medical care, rehabilitating and releasing the healthiest orangutans back into the wild. This is both the story of their life-saving work and of how one of our closest wild relatives has been pushed to the brink of extinction. Combining genuine rescue footage with contributions from experts throughout, this documentary looks toward the future and asks what hope remains to save the orangutan.

Human mothers raise fetuses inside their wombs and breast feed their babies for a long time after birth. What made humans evolve so that we raise our children so affectionately? The latest research reveals an unexpected origin of mothers' affection toward their children. Scientists believe that our ancestors experienced unforeseen dramatic changes in DNA under threats of extinction. These DNA changes caused humans to be devoted to raising children. Learn about the scientific interpretation of the evolutionary roots of your affectionate bonds with your kids.

A close-up view of sex, bug-style, as David Attenborough talks viewers through the different ways in which creepy-crawlies reproduce. Size matters for the minuscule male orb spider, creepily sneaking up on its intended and trying to mate without her noticing, while there's no rest for the lothario-like butterfly, which has plenty of notches on its proverbial bedpost. However, the harvestman spider has no use for sex at all, and reproduces by cloning itself.

In this episode, Iolo investigates the courtship and nesting behaviour of birds, including the amazing courtship display of great crested grebes at a reservoir near Pontypool, the impressive sky dance of hen harriers in the dramatic Cambrian Mountains, how nuthatch use mud like cement to prepare their nest in a woodland near Harlech, and why long-tailed tits near Newtown are exceptional nest builders. On the Lleyn Peninsula near Trefor, he looks at why one colony of shags nest earlier than any others in Wales, and in Pembrokeshire he finds out where house martins nested before they used our buildings. Iolo also looks at the variety of places birds like to nest, from little ringed plovers on shingle banks along the River Tywi to puffins underground on Skomer.
