Age estimates of phylogenetic tree nodes and 95% confidence intervals.

Node code	Estimated age of the node (in Myrs)	95% confidence interval (in Myrs)
A	7.450	5.776 - 9.271
B	6.742	4.892 - 8.613
C	2.348	1.631 - 3.124
D	1.772	0.921 - 2.725
E	3.146	2.104 - 4.298
F	1.364	0.766- 2.025
G	5.332	3.688 - 7.067
H	1.846	1.210 - 2.545
I	1.259	0.742 - 1.060

Estimations were performed by analysing all the haplotypes and assuming a Yule prior. The node codes are given in Figure 2.
