They have also played major roles in the remarkable biological advances of the past century. The smallpox virus was humanity’s greatest killer, and yet it is now one of the only diseases to have been eradicated from the globe. New viruses, such as HIV, continue to pose new threats and challenges. Viruses are unseen but dynamic players in the ecology of Earth. They move DNA between species, provide new genetic material for evolution, and regulate vast populations of organisms. Every species, from tiny microbes to large mammals, is influenced by the actions of viruses. Viruses extend their impact beyond species to affect climate, soil, the oceans, and fresh water. When you consider how every animal, plant, and microbe has been shaped through the course of evolution, one has to consider the influential role played by the tiny and powerful viruses that share this planet.
