Quizplus · Accepted Answer

The likely order of evolution of snake venom starts with a single copy of the defensin gene (III), followed by duplication of this gene (II), then the recruitment of these genes in the venom gland (IV), and finally the diversification of venom genes (I). This sequence suggests an initial genetic simplicity evolving towards complexity and specialization in venom production.
