Median estimate of the TMRCA (in million years before present) for the mtDNA data set.

Lineage	TMRCA four-fold	TMRCA 2.1%	TMRCA 6.1%
debilis sensus lato	3.1 (1.2-7.7)	7.7 (6.0-9.7)	2.6 (2.0-3.2)
rabai	0.25 (0.08-0.7)	0.8 (0.6-1.1)	0.3 (0.2-0.4)
debilis	0.15 (0.02-0.5)	0.6 (0.3-0.9)	0.2 (0.1-0.3)
rabai/debilis	1.1 (0.3-2.3)	2.8 (2.1-3.7)	0.9 (0.1-1.2)
albigula	0.4 (0.1-0.9)	0.6 (0.4-0.9)	0.2 (0.1-0.3)

Values in brackets are the 95% HPD. TMRCA were estimated using an uncorrelated lognormal molecular clock model, coalescent prior with constant population size and a mean rate of evolution for the four-fold degenerated sites of 0.073 s/s/myr (95% CI: 0.025-0.123 s/s/myr); 192 sites were included in the analyses.
