Summary:
Evolution offers a groundbreaking and definitive view of the extraordinary impact the evolutionary process has had on our understanding of the world around us. Beginning with Darwin's revolutionary theory, this seven-part series explores all facets of evolution--the changes that spawned the tree of life, the power of sex, how evolution continues to affect us every day, and the perceived conflict between science and religion. The Evolutionary Arms Race: "Survival of the fittest." Raw competition? Or, a level of cooperation indispensable to life? Evolution tells us that both are important. We explore our own spiraling arms race with microorganisms, the only entities that can pose a threat to our existence. We follow the struggles of medical detectives uncovering the roots of epidemics and trace the alarming spread of resistance among pathogens that cause disease, like the new virulent tuberculosis--nicknamed "Ebola with wings." Interactions between species are among the most powerful evolutionary forces on earth, and understanding them may be key to our own survival. Why Sex?: In evolutionary terms, sex is more important than life itself--without progeny, we are evolutionary losers. Sex fuels evolutionary change, by adding variation to the gene pool and eliminating unsatisfactory traits. We look at the endless variety of sexual expression and the powerful hold sex exerts over almost all living things. And we explore how the need to pass on our genes has shaped our own bodies, minds, and lives. Some scientists believe that art, literature, music--in fact all of human culture--may be the ultimate result of our sexual drives. Special DVD features include: Access to the Evolution Web site, featuring interactive games and activities, a comprehensive evolution library, online teacher course and student lessons, a printable teacher's guide, an evolution glossary and FAQs, and more. On four DVD5 discs. Region coding: All regions. Audio: Dolby stereo. Screen format: Letterboxed.
