Virology Lectures 2024 #21: Evolution

Viral evolution is the constant change of a viral population in the face of selection pressures. Viral evolution occurs faster 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.

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. I do not run ads on our work as it is disruptive to learning.
