Venom systems are functional and ecological traits, typically used by one organism to subdue or deter another. A predominant subset of their constituent molecules-"toxins"-share this ecological function and are therefore molecules that mediate interactions between organisms. Such molecules have been referred to as "exochemicals." There has been debate within the field of toxinology concerning the evolutionary pathways leading to the "recruitment" of a gene product for a toxic role within venom. We review these discussions and the evidence interpreted in support of alternate pathways, along with many of the most popular models describing the origin of novel molecular functions in general.
