Table 3. Early-diverging lineages with peripheral geography and relatively limited diversification represent phylogenetic evidence for diversification by barrier displacement (Albert et al. 2018). Examples from Cyprinodontidae, Fundulidae, and Goodeidae are provided here. Sister clades are provided for comparison with each peripheral lineage. The chronogram node (Fig. 3) is given for each sister relationship
