  9. Chen Z, Wang Z, Xu S, Zhou K, Yang G. Characterization of hairless (Hr) and FGF5 genes provides insights into the molecular basis of hair loss in cetaceans. BMC Evol Biol. 2013;13:34 pubmed publisher
    ..Consequently, the hair follicle cycle was disrupted and the hair was lost completely due to the loss of the Hr gene function in cetaceans. This suggests that cetaceans have evolved an effective and complex mechanism for hair loss...
