The three genetically homogeneous European subgroups were individually compared with the pooled NW Pacific samples. More details in Additional file 3: Table S2.

a Upper limits for prior distribution of θ set to 1000.

b Upper limits for prior distribution of θ were set to θNWP=1000, θEur=100 and θA=100.

* The analysis did not converge.
