Poisonous frogs, a broad polyphyletic group within the order Anura, often use one such method known as target site insensitivity, which is the alteration of the molecular target of the toxin to disallow the toxin from binding. Researchers from University … Continue reading Poison Frogs: Evolution of Epibatidine Resistance
