Fig. 2

Hypothetical plot showing the position of three populations (A, B, and C) at two points in time (circles earlier, squares later). The plus sign is the average value for all populations for the variables used in this analysis. Arrows indicate how FST is calculated; it is the average value of each population from the overall mean of those populations (large black arrows). This figure shows the same populations at time = 2 (squares). The distances between populations are smaller and all squares are closer to the center of the plot (small gray arrows). This indicates that genetic integration increased among these populations through time, likely due to increased gene flow and migration among them. One can also compare variability within a population through time (large gray arrow). Patterns of within and between population variation as well as distances among samples are critical to evolutionary inferences
