The Red Queen hypothesis has been proposed as a model for antagonistic interactions where species (for example, host-parasite, prey-predator, and victim-exploiter) perpetually co-evolve in winnerless dynamics (1, 2, 5, 6). In host-parasite interac-tions, the Red Queen hypothesis suggests that coevolution occurs as a

Web13. jan 2024 · Background Red Queen dynamics are defined as long term co-evolutionary dynamics, often with oscillations of genotype abundances driven by fluctuating selection in host-parasite systems. Much of our current understanding of these dynamics is based on theoretical concepts explored in mathematical models that are mostly (i) deterministic, …
