Phylogenetic relationships and divergence times among six carnivore species. The topology was calculated from a 7,589,724 nt long data set, and the divergence times were based on three well established fossil calibration points inside Carnivora. The cat was used as an outgroup (not shown). The values at each branch indicate the estimated mean divergence time (million years ago) ± standard deviation. The scale bar is in million years (Ma)
