Simone Avogadro di Collobiano, Kim Christensen, and Henrik Jeldtoft, Jensen

TL;DR
This paper demonstrates that the Tangled Nature model can be interpreted as a general quasi-species model with frequency-dependent fitness, providing theoretical insights into mutation thresholds and macroevolutionary patterns observed in simulations.
Contribution
It offers a detailed theoretical derivation linking microevolutionary dynamics to macroevolutionary phenomena in the Tangled Nature model, extending quasi-species theory.
Findings
Identification of a mutation threshold consistent with simulations
Demonstration of periods of stasis and bursts in evolution
Showcasing how mutation rate influences species formation
Abstract
We show that the Tangled Nature model can be interpreted as a general formulation of the quasi-species model by Eigen et al. in a frequency dependent fitness landscape. We present a detailed theoretical derivation of the mutation threshold, consistent with the simulation results, that provides a valuable insight into how the microscopic dynamics of the model determine the observed macroscopic phenomena published previously. The dynamics of the Tangled Nature model is defined on the microevolutionary time scale via reproduction, with heredity, variation, and natural selection. Each organism reproduces with a rate that is linked to the individuals' genetic sequence and depends on the composition of the population in genotype space. Thus the microevolutionary dynamics of the fitness landscape is regulated by, and regulates, the evolution of the species by means of the mutual interactions.…
