Virology Lectures 2017 #21: Evolution

Viruses epitomize evolution by natural selection, and for RNA viruses, this process happens so quickly that it can be observed in real time. In this lecture you will learn all about how viral evolution works - what creates viral diversity, the nature of viral populations, and how selection works. We'll also explore the evolution of viral virulence, and the origin of viruses. Charles Darwin would have loved viruses!
