Paul Turner describes the fundamental biology of viruses, how they interact with their host organisms, and how they might have originally evolved long ago. He provides an overview of the many reasons why viruses might be considered the most biologically successful inhabitants of earth, including their ability to rapidly reproduce, and adapt to environmental challenges. Turner also provides an introduction to phage therapy to treat bacterial infections, and how it can be improved by applying "evolution thinking."
