Extreme Animal Weapons ()
Overview
NOVA: Extreme Animal Weapons From lobster claws and dog teeth to bee stings and snake fangs, every creature depends on a weapon. But some are armed to extremes that make no practical sense - whether it's bull elks with giant 40-pound antler racks or tiny rhinoceros beetles with horns bigger than their body. What explains giant tusks, horns and claws that can slow an animal down and even impair health and nutrition? Showcasing astonishing wildlife cinematography, Extreme Animal Weapons investigates the riddle of outsize weaponry and uncovers a bold new theory about what triggers an animal arms race. In creatures as varied as dung beetles and saber-toothed tigers, shrimp and elephants, the same hidden factors trigger the race and, once started, these arms races unfold in exactly the same pattern. In this enthralling special, NOVA cracks the secret biological code that underlies nature's battleground.

The Himalayas
The highest mountain range in the world, the Himalayan range is far reaching, spanning thousands of miles, and holds within it an exceptionally diverse ecology. Coniferous and subtropical forests, wetlands, and montane grasslands are as much a part of this world as the inhospitable, frozen mountaintops that tower above. The word Himalaya is Sanskrit for abode of snow, fitting for a stretch of land that houses the world’s largest non polar ice masses. Extensive glacial networks feed Asia's major rivers including the Ganges, Indus, and Brahmaputra. More than a billion people rely on these glacier-fed water sources for drinking water and agriculture. The Himalayas are not only a remarkable expanse of natural beauty. They're also crucial for our survival.

The Alps
The Alps – wild mountains, extreme lives, but also a magical world. This majestic mountain range connects eight countries and reaches heights of up to 4,000 metres above sea level. At a length of 1,200 kilometres, the Alps form both a connecting bridge between western and eastern Europe and a high barrier between southern and central Europe. The mountains act as a mighty water reservoir and continental watershed, feeding innumerable rivers that flow into three different oceans. Their highest peak, Mont Blanc, is surrounded by long, soaring mountains with ice-covered slopes. These great summits are just one reason the so-called “Roof of Europe” continues to fascinate – across the continent and around the world. The incredible diversity of landscapes, flora and fauna makes the Alps a unique natural treasure at the heart of Europe.

Iceland: The Quest for Origins
The fascinating landscape formations of Iceland in the North Atlantic bear witness to the beauty and primal power of nature. They were created through the interaction of powerful volcanic, geological and biological processes that have been changing the face of the earth for billions of years. This is what the Earth might have looked like four billion years ago. Iceland is the realm of ice and fire. Nowhere else is there such a high density of volcanoes. The landscapes, which are continually reshaped by eruptions, make the island a natural laboratory full of clues about the formation and development of the earth. The documentary follows a group of scientists through the most active areas of Iceland, along a mountain range that has emerged from the ocean. On the slopes of the volcanoes, in the fog of the fumaroles and on streams and rivers, the three researchers explore how the first forms of life populated the earth's surface and in what evolutionary steps they took over the earth.
