The importance of being discrete in sex
Renato Vieira dos Santos

TL;DR
This paper models the evolutionary dynamics of sexual species using nonequilibrium statistical mechanics, revealing how discrete interactions can naturally lead to the prevalence of sex in nature.
Contribution
It introduces a novel application of field theory and renormalization group analysis to evolutionary biology, connecting stochastic processes with the Red Queen hypothesis.
Findings
Discrete nonlinear interactions promote sexual species prevalence.
Spatiotemporal stochastic processes provide insights into evolutionary stability.
Model scaling reveals emergent properties of complex biological systems.
Abstract
The puzzle associated with the cost of sex, an old problem of evolutionary biology, is discussed here from the point of view of nonequilibrium statistical mechanics. The results suggest, in a simplified model, that the prevalence of sexual species in nature can be a natural and necessary consequence of the discrete character of the nonlinear interactions between couples and their pathogens/parasites. Mapped into a field theory, the stochastic processes performed by the species are described by continuous fields in space and time. The way that the model's parameters scale with subsequent iterations of the renormalization group gives us information about the stationary emergent properties of the complex interacting systems modeled. We see that the combination of one aspect of the Red Queen theory with the stochastic processes theory, including spatiotemporal interactions, provides…
