“…Several studies in this special issue draw inference from WGS data to gain new insights into demographic and evolutionary histories. For example, effective population size changes are inferred through time using variation in coalescent rates in individual genomes, and cross‐coalescence between genomes from canids, caribou, horses, killer whales and sea turtles (see Sarabia et al (2021); Taylor et al, (2021); Vershinina et al, (2021); Foote et al, 2021; Torres Vilaça et al, 2021 respectively). As noted by Vershinina et al, 2021, (and illustrated by Foote et al, 2021, Sarabia et al, 2021, Taylor et al, 2021 and Torres Vilaça et al, 2021), even just a few nuclear genomes can provide estimates of gene flow versus isolation, even within and among species with complex evolutionary histories.…”
