Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size
