Resistance to toad toxin shows evolution can repeat itself

In a paper published today in the journal PNAS, researchers examine the response of a variety of insects, reptiles, amphibians and mammals to a natural selection pressure in the form of cardiac glycosides -- toxins produced by certain plants and toads for defense against predators.
