Ancestral character state reconstruction using stochastic character mapping for the eye-trait morphology (Blind, Micro and Normal-eyed morphs) on a time calibrated phylogeny of using a “standard clock” estimate. A, B, C and D are four major clades. Posterior probabilities of node support values of 100% are indicated by *. Key events of Sinocyclocheilus evolution includes; at least three independent evolutionary events for Blind morphs; Blind, Micro-eyed and a few Normal-eyed species in Clade B, with two cases of reversal from either Micro-eyed or Blind to Normal-eyed species. Sinocyclocheilus diversification seems to have initiated in the mid-Miocene with the aridification of China
