On the front lines of the hunt for killer viruses, a shocking discovery is made: viruses, once thought to be a menace to humankind, may in fact be the ultimate creators. Since the beginning of time, they have played a critical role in evolution, shaping us and perhaps even creating us. How could that be? How can an entity seemingly programmed for destruction lead to genetic diversity and new species? To many people, viruses are simply agents for disease, but to Dr. Luis Villarreal, Director of the Center for Virus Research at the University of California Irvine, they may possess far greater power than originally thought. He guides us through evidence that viruses gave rise to the first complex cells, played a role in the diversification of life, changed how our young are born, drove evolution, and perhaps gave us emotions. One expert even suggests that an ancient virus could have entered our genes and rewired us for monogamy. National Geographic investigates a provocative new theory that suggests that all life - including humans - is descended from viruses. Taking us through African jungles in search for new strains, this episode of Explorer presents a startling new view of viruses - toward what may be a remarkable evolutionary moment: the rise of a new human species.
