Models used to test the divergence history (left) and s values for 100 simulated coalescent genealogies (right).
(a) Recent divergence hypothesis; (b) Stepwise divergence hypothesis with constant demographic history; and (c) Stepwise divergence hypothesis with demographic decline (thin lines) in the Yellow/Bohai Sea and the Taiwan Strait during the LGM. The bars show the expected distribution of the s value using the mode of Ne with the 95% CI indicated by dashed lines. The red lines show the s values for the actual sequences under each hypothesis.
