Bayes factor analyses of marginal likelihoods

	Log-likelihood, lnL	SD	Δ2lnL
All data
Outgroup constrained	−30,842.156	8.32	−245.6
Relaxed clock	−30,719.351	12.30	0.0
Strict clock	−30,843.256	9.46	−247.8
Cytochrome b
Outgroup constrained	−11,715.948	9.46	−196.0
Relaxed clock	−11,617.934	11.29	0.0
Strict clock	−11,997.605	9.36	−759.4

Analyses of marginal tree likelihood distributions with Bayes factors suggest that a relaxed clock model explains the data better (higher lnL) than either a strict clock or forcing Leucocytozoon to an outgroup position.
