The evolutionary consequences of population spread on curved surfacesDaniel A. Beller1, Kim M. J. Alards2, Ricardo A.

We investigate the evolutionary dynamics of populations growing and expanding on curved surfaces. Using a combination of individual-based simulations and theory we characterize the effect of individual features (cones and spherical caps) on the shape of the population front and the genetic composition of an expanding population. We find that, on sufficiently large scales, geodesics allow us to describe both population and evolutionary dynamics quantitatively. Using these findings, we characterize the consequences of large-scale surface roughness on genetic diversity and compare to the case of heterogeneous but flat environments.
