a Sea-level changes during the last 700 thousand years before present (kyr BP; [21]). Seven noticeable epochs of the sharp sea-level declines are marked with the stages of MIS [42]. b Divergence time estimates of lineages representing the four peripheral insular domains of Apodemus speciosus, based on a Bayesian strict molecular clock applied to the mitochondrial cytochrome b (Cytb) sequences (1,140 bp). The vertical bars indicate the 95 % highest posterior density intervals
