Figure 3From: Phylogeography and evolutionary history of the Crocidura olivieri complex (Mammalia, Soricomorpha): from a forest origin to broad ecological expansion across AfricaDatation tree of the Crocidura olivieri complex. Dating tree built using data of the three mitochondrial markers (16S, cytb and COI) based on 2403Â bp and Bayesian Inference under a Yule model of speciation and a log-normal relaxed molecular clock model. a) Complete tree showing the four fossil calibration points used as time constraints: oldest record of Crocidura (*), oldest Otisorex (**), oldest Cryptotis (***), oldest recorded Myosoricinae-Crocidurinae (****) and split between Soricinae and Crocidurinae-Myosoricinae (*****). b) Focus on the C. olivieri complex with notations at nodes of Bayesian posterior probabilities (above line) and estimated times of divergence and credibility intervals within brackets (below line).Back to article page
