Erratum to: Phylogeny and divergence of the pinnipeds (Carnivora: Mammalia) assessed using a multigene dataset
BMC Evolutionary Biology volume 8, Article number: 216 (2008)
After publication of our article , we discovered that one of the programs used to date the supertree, relDate v2.2 , contained a bug that can lead to errors in the date estimates it provides. The precise effect of the bug is dependent on tree shape, but it generally results in overestimates of divergence-time estimates, particularly for nodes that are closer topologically to the tips of the tree. It can potentially, however, affect every date estimate on a tree.
Fortunately, the impact of the bug on date estimates in the pinniped supertree was minimal. Only 14 of the 35 nodes were affected, with the mean and median absolute errors for the dates of these 14 nodes being 0.19 and 0.10 million years (= 8.9% and 6.1% relative to the corrected date). All but one error (that for node 14) were overestimates. The largest difference was 0.5 million years (for node 6), and the two sets of dates are perfectly correlated with one another (correlation coefficient = 1.000, Z = 28.508, P < 0.0001).
Corrected dates and 95% confidence-interval dates for all nodes in the pinniped supertree can be found in Table 1 and should be used in place of those reported in the original publication . We apologize for any inconvenience this error might cause.
