Mitochondrial DNA Phylogeny of the family Cichlidae:
Monophyly and Fast Molecular Evolution of the Neotropical Assemblage: Figure 4

Fig. 4. Frequency distribution of genetic distances among cichlids (HKY + Γ distances). Path lengths across the ME tree from the most common recent ancestor (MRCA, see inset) to Neotropical genera (Neo = hatched bars) and African genera (Afr = solid bars; Mad = Madagascan/Indian cichlids). In order to minimize the effect of non-independence among distances, a single representative of each Neotropical genus was used when more than one species per genus was available. A slower rate is inferred for African cichlids based on a shorter path length from Madagascar/Indian to African cichlids than to Neotropical cichlids.
