Monsanto’s Roundup, which is the most popular herbicide used today, has been found to ignite morphological changes in amphibians. The research, conducted using tadpoles, found that environmentally relevant concentrations of Roundup are enough to cause two species of amphibians to actually change shape. This is the first research to show that herbicides can have such an affect on animals.
While it wasn’t surprising to see morphological changes take part due to the naturally emitted chemicals from predators, it was rather shocking to find out that Roundup had the same effects — causing the tails of the tadpoles to grow in size. What’s more, the combination of the naturally emitted chemicals and Roundup caused the tadpoles’ tails to grow twice as large. Seeing as tadpoles alter body shape in order to properly survive in its environment, the forced changes from herbicides like Roundup can put the animals at a disadvantage.
