Figure 4.

Congruence of divergence time estimates (A) and their associated standard deviations (SD) (B) when calculated with different partition types. The X-axis represents the estimates without partitioning and the Y-axis the ones with 5, 9 or 12 partitions (see Methods). The age estimates increase with the number of partitions (A) and the SDs are larger for extreme numbers of partitions (none and 12 partitions) (B). For clarity purpose only the age estimates relative to tenrecs are displayed in these graphs; however the estimated ages and SDs in the rest of the tree give the same results.
