Chronogram showing divergence time estimates. The chronogram was calculated based on the BI consensus tree. Divergence times were estimated using a partitioned Bayesian analysis implemented in BEAST. The following time constraints were used: A1 53–84 mya (uniform prior), published age estimate based on non-cichlid fossils [24] and O1 5.98 mya (lower bound), the age estimate for Oreochromis lorenzoi† [31]. The chronogram shows 95% credibility intervals (HPC, grey bars). For nodes marked with letters, age estimates (95% HPC and mean heights) are given in Table 1. Calibration points (O1 and A1) are marked with black squares. For simplification clear monophyletic groups were combined (shown as triangles).
