Viral evolution is the change of a viral population under selection pressures. Evolution occurs faster in viruses than in other organisms because viruses produce so many progeny harboring many genome mutations. In this lecture we consider the four main drivers of viral evolution: large numbers of progeny, mutation, selection, and quasispecies effects, and discuss where viruses came from and where they are going.

– Who Am I? –
I’m Vincent Racaniello, Earth’s Virology Professor, and I believe that education should be free.
I’m also a professor of virology at Columbia University in New York. I’ve been doing research on viruses since 1976, and teaching virology in classrooms and online since 1999. On this YouTube channel I share videos of my lectures, MicrobeTV podcasts, and more.
New videos are uploaded several times each week.
