n: number of sequences used for calculation; S: segregation site within the population; texp: time since expansion; the range in parentheses indicates the 95% confidence interval (CI) for τ and the upper and lower bounds of texp using substitution rates of 0.6% and 1.2%; the P values are highlighted in bold when they are significant after correcting for multiple tests (FDR = 0.05%).
