Gene moonlighting can occur merely through changes in expression, which may result from as little as a single mutation; it does not require the meandering process of random alteration and selection implied by the duplication and neofunctionalization model.
Based largely on studies of snakes, spiders and other species dangerous to our own, it is thought that most venom genes arise through the mechanism of gene duplication followed by mutation and repurposing (which scientists refer to as neofunctionalization).
In fact, less than 10 percent of the toxin genes clearly arose through duplication and mutation.
One reason is that evolution changes genomes through the duplication and specialization of genes.
