The values of the neutrality tests for each lineage were examined by Tajima’s D and Fu’s Fs statistics. Goodness of fit of observed-to-theoretical mismatch distributions under a sudden (stepwise) expansion model (Rogers and Harpending 1992) is test with the sum of squared deviations (SSD) and Harpending’s raggedness index (HRag). Upper and lower 95% confidence limits around estimates of τ and associated ranges of t (in million years before present, Ma) are in parentheses.
