Comparison of migration models between the composite populations ‘North’ and ‘South’ (see text for details of groupings)

Migration model	Raw thermodynamic	Bezier approximation	Harmonic mean	BF (Bezier)
North ↔ South	−4140.47	−1280.5	−332.94	2.7501E−78
North → South	−3091.46	−1101.91	−303.67	1
South → North	−6237.74	−1591.44	−294.11	2.5109E−213

MCMC long chains were 40,000 recorded steps. Three log probability scores are calculated by Migrate (raw thermodynamic, Bezier approximation, and Harmonic mean), while the final column gives the Bayes factors based on the Bezier approximation scores
