PRODUCT SUMMARY
This National Geographic program explores the theory that humans and all other life forms descended from viruses. While most people think that viruses lead to disease, some experts suggest that viruses played a role in the diversification of life, gave humans emotions, changed how humans are born, drove evolution and more. Another scientist believes that an ancient virus may have entered human genes and reprogrammed them for monogamy.
