Venom Evolution: Gene Loss Shapes Phenotypic Adaptation.

Current biology : CB - 26 Sept 2016

Casewell Nicholas R

Abstract excerpt

Snake venoms are variable protein mixtures with a multitude of bioactivities. New work shows, surprisingly, that it is the loss of toxin-encoding genes that strongly influences venom function in rattlesnakes, highlighting how gene loss can underpin adaptive phenotypic change.
