The Washington Post just reported on a new study by Tyrone Hayes, star of THE FROG SCIENTIST. Tyrone exposed some African clawed frogs to atrazine in his lab and produced frogs that are genetically male but lay viable eggs. The transsexual frogs were produced at atrazine levels that are allowed in tap water.
