BIRD GENE REACTIVATION. “In conclusion, given the set of Passeriformes bird species currently known to be able and unable to synthesize vitamin C and the currently accepted phylogenetic relationships of these species, one can deduce that the ability of synthesizing vitamin C has been unequivocally reacquired at least twice, once in the Corvus/Dendrocitta lineage and once in the Turdoides lineage.”
