In stark contrast to the typical evolutionary story, the researchers stated, “We find the hypothesis that snake venom evolves through the duplication of physiological or body genes and subsequent recruitment into the venom gland to be unsupported by the available data,” and, “Indeed for a large number of the gene families claimed to have undergone recruitment we find evidence of a diverse tissue expression pattern, including the salivary gland of nonvenomous reptiles.” The significance of this finding indicates that venom genes are not the products of alleged evolutionary processes, but are important DNA sequences that also serve other purposes in a variety of reptile tissues. icr.org/article/8513
