Restriction and recruitment - gene duplication and the origin and evolution of snake venom toxins
Adam D Hargreaves, Martin T Swain, Matthew J Hegarty, Darren W Logan, John F Mulley
This study challenges the hypothesis that snake venom toxins evolve through gene duplication and recruitment by showing that venom toxins are expressed in non-venomous tissues and result from subfunctionalisation of salivary proteins.
