Viral evolution is the change of a viral population in the face of selection pressures. Viruses produce so many progeny harboring many genome mutations, making evolution faster than in other organisms. In this lecture we consider the four main drivers of viral evolution: large numbers of progeny, mutation, selection, and quasispecies effects. We close with a consideration of where viruses came from and where they are going.

– Who Am I? –
I’m Vincent Racaniello, Earth’s Virology Professor.
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, podcasts, and more.
New videos are uploaded several times each week.
