The genomic origins and evolutionary path to a key innovation in the world's most venomous snakes

Jory van Thiel, Noah L. Dowell, Cara Francesca Smith, Elda Eliza Sanchez, Sean B. Carroll

This study traces the genomic origins of four procoagulant venom toxins in Australian snakes and identifies a fifth toxin, showing two distinct evolutionary paths for their development.

Loss of a major venom toxin gene in a Western Diamondback rattlesnake population

Noah L. Dowell, Elizabeth Cahill, Sean B. Carroll

The paper investigates the loss of a major venom toxin gene, MPO1, in Western Diamondback rattlesnakes, finding it correlates with geographic distribution and is caused by inactivating mutations.
