Snake Venom Snag
The genetics of snake venom driving evolution has recently emerged as a popular field of investigation. A new study published in the journal Molecular Biological and Evolution, however, has uncovered a critical new snag.
The evolution of snake venom had been hypothesized to originate through a gene duplication process followed by the actions of natural selection leading to increased venom toxicity over time. However, the research team lead by Todd Castoe (pictured), Assistant Professor of Biology at the University of Texas, has discovered a genetic snag challenging this once popular gene duplication theory.
