The dog is the ultimate human creation. With 400 breeds and counting, the dog is more varied in size and behavior than any other species on the planet. National Geographic looks at man's evolutionary manipulation of dogs' appearance, talents and temperament - and the accelerating efforts to create breeds to suit our needs (more than 80 percent of today's breeds did not exist 150 years ago). From desirable traits like supersensitive hearing and smell to the unintended consequences of genetic diseases, learn how nature and man have partnered to deliberately create new and specialized versions of man's best friend.

A team of scientists clambers down into the steep crater of an active volcano in central Africa, a lake of molten lava seething far below. The team's mission is to explore this deadly mountain up close to find out when and why it is likely to erupt next. the lives of half a million people living directly in its shadow are at stake. In January 2002, the ground close to the city of Goma in the Democratic Republic of Congo split open and rivers of lava swept through entire neighborhoods, killing some 100 people and leaving 120,000 homeless. The volcano towering over the city, Mount Nyiragongo, had awoken again. Now French volcanologist Jacques Durieux and his team worry that, next time, deadly lava could erupt from cracks directly under the city itself.
