The diversity of evolutionary rates

Jakub Otwinowski (Department of Biology, University of Pennsylvania, Philadelphia)

We have evidence of evolution happening over billions of years, yet we have little understanding of how long it takes for anything to evolve. In other words, we often do not understand quantitatively what affects the rate of evolution over long time-scales. I will show how spatial structure can impede the rate of evolution with a model related to surface growth physics. The fitness landscape is also an important factor in the rate of evolution, and I will discuss how it can be approximated from high-throughput sequence-function experiments. Finally, I show how the rate of evolution can be defined in coevolving populations with non-equilibrium measures of adaptation.
