Part two of two. Explorer Benedict Allen is determined to get disabled journalist Frank Gardner into the wilds of Papua New Guinea, despite having to grapple with Frank's wheelchair. As the terrain gets even tougher to negotiate, the pair know they must make an epic journey into the highlands, crossing through two tribal territories to achieve their objective. However, as Frank gets close to realising his dream of seeing wild birds of paradise up-close, his old injuries return to haunt him and the expedition hangs on a knife edge.

Can animals count? This is a question that has intrigued and fooled investigators for a long time. Just over 100 years ago, a German horse called Hans was declared a mathematical genius but all was not as it seemed. And strangely, some bamboos around the world flower exactly at the same no matter where they are. Are they counting down the years?

The beautiful, mysterious world of rain is visualized using the latest filming technology. Ultra-high speed cameras capture breathtaking images in Odaigahara, the rainiest area in Japan that receives an annual rainfall of 5,000 millimeters. On the ground form lakes that only appear after summer heavy rains, allowing rare frogs to thrive. In winter, a unique natural phenomenon called Glazed Frost takes place if rain falls unfrozen and the air temperature is below zero. Through poetic cinematography, we discover just how rain enriches the natural beauty in Japan, a country unusually blessed with rain.

Grasslands cover one quarter of all land and support the vast gatherings of wildlife, but to survive here animals must endure the most hostile seasonal changes on the planet. From Asia's bizarre-looking Saiga antelope to the giant anteaters of Brazil, grassland animals have adapted in extraordinary ways to cope with these extremes. In the flooded Okavango, lions take on formidable buffalo in epic battles, on the savannah bee-eaters take advantage of elephants to help catch insects and, on the freezing northern tundra, caribou embark on great migrations shadowed by hungry Arctic wolves.

Metamorphosis seems like the ultimate evolutionary magic trick - the amazing transformation of one creature into a totally different being: one life, two bodies. From Ovid to Kafka to X-Men, tales of metamorphosis richly permeate human culture. The myth of transformation is so common that it seems almost pre-programmed into our imagination. But is the scientific fact of metamorphosis just as strange as fiction or... even stranger? Filmmaker David Malone explores the science behind metamorphosis. How does it happen and why? And might it even, in some way, happen to us?
