Observations of frog deaths and body malformations in frogs have been taken by some to be warnings of possible environmental effects on humans. Scientists have also genetically engineered headless tadpoles, which led to speculation that headless people may be genetically created in the future for organ donation harvest. Frogs have been used to study the effects of space flight, which include changes in the lungs, tails, growth, and behavior. Although frogs may sound like perpetual victims (it’s not easy being green), they are actually a resilient species, being one of the unexpected survivors from the Mt. St. Helens volcanic eruption. In fact, the western toad experienced a population boom there because they fed of the algae that resulted from the lack of lakeshore trees and because their predators (snakes and birds) had not yet recovered. The findings helped ecologists better understand the resilience of some species and ways that some species can survive natural disasters. Yes, folks, Kermit the Frog truly rules and science owes him a lot.
