Adam Rutherford meets a new creature created by American scientists - the spider-goat. It is part goat, part spider, and its milk can be used to create artificial spider's web. It is part of a new field of research, synthetic biology, with a radical aim: to break down nature into spare parts so that we can rebuild it however we please.

Sri Lanka: Elephant Island

Sri Lanka, the tropical island lying off the southern coast of India, is home to its own special elephants. A subspecies of the Asian elephant, they have their own unique characteristics. In this programme, award-winning wildlife cameraman Martyn Colbeck of Echo of the Elephants fame travels to Sri Lanka to try and get to know them. Martyn has planned his arrival to coincide with the start of the monsoon, hoping it will be the best time to find and follow a newborn calf. By drawing on local knowledge, Martyn begins to unravel the complex social world of Sri Lanka's elephants - he witnesses a fight over a calf, a battle between two bulls in musk and, at an elephant sanctuary, befriends an orphaned elephant who sadly lost a leg to a snare and is facing an uncertain future.

Making Worlds

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.
