In the final episode of this three part series, cutting-edge science and archaeology are reconstructing the life and culture of The Iceman—the 5000-year-old frozen corpse found buried in the ice of the Alps. By analyzing every inch of the Iceman's body and the tools and equipment found with it, scientists are piecing together the most complete picture yet of the late Stone Age in this part of Europe. X-ray, CAT scan, and microscopic analysis of this spectacular find is revealing where the iceman lived, what he ate, and how he may have died; nuclear physics reveals that the Iceman's hair was contaminated with arsenic and copper, suggesting he was involved in copper production centuries before it was known to exist in the region.

The pearl. The only gem produced by a living animal, has long carried a certain allure. Yet the best mollusk for making this gem, the pearl oyster doesn't always produce a pearl, and even then, the pearls are rarely perfectly round. It wasn't until the late nineteenth century, when a Japanese scientist discovered a technique to incite oysters to produce these gems, that an industry was formed. Inducing an oyster to create a pearl is only half the battle—the oyster then needs a nutrient-rich, open environment in which to grow. This NOVA program looks at the science of pearl farming, follows efforts of oyster farmers trying to cope with growing problems of pollution and overcrowding, and considers the shifting sands of dominance within the pearl industry.
