a
Using an alignment of 276-bp of 1st and 2nd codon positions for 18 SFV taxa and 500-bp of all codon positions for 31 cytB taxa. Million years (MY) ago. Geometric means inferred using Bayesian methods and a relaxed clock; ranges in parentheses are 95% highest posterior density intervals.
b
Dating and fossil estimates from Perelman et al. 2011 [30].
c
ND, not determined.
d
NA, not available.
