Fig. 4
a Dated phylogeny using the concatenated dataset (twelve proteins and two rRNAs) with three calibration points (red dots indicate time-calibration markers, â‘ : Cavender, 1986 [31]; â‘¡: Liu and Chang, 2009 [32]; â‘¢: Harrison, 1992 [33]), and b using cytb gene with two calibration points (red dots indicate time-calibration markers, â‘ : Liu and Su, 1962 [23]; â‘¡: Jeffries et al., 2016 [24]) to estimate the divergence of Carassius. Node ages are shown together with 95% highest posterior density bars indicating a range of age estimates
