Figure 5. Relationship of genomic differentiation as measured by FST and species-specific characteristics. (A + C) Relationship of FST and hand-wing index showing (A) raw data and (C) phylogenetic independent contrasts (PIC). (B + D) Relationship of FST and harmonic mean population sizes through time showing (B) raw data and (D) PIC. Genomic differentiation as measured by FST has no strong linear relationship with measured characteristics of each species. Hand-wing index and population sizes were included as the mean value for all individuals per species that were sampled for this study.
