Darwin’s nightmare: Toxic toad evolves to secure supremacy – Yahoo! News

PARIS (AFP) – He’s fat, ugly and poisonous — and he’s mutating. He’s the cane toad (Bufo marinus), a species which was introduced into the Australian state of Queensland 70 years ago to tackle insect pests in canefields and has since become an ecological catastrophe.

Weighing in at to up two kilos (4.4 pounds), the unwanted anuran has extended its range to more than a million square kilometers (386,000 square miles) in tropical and sub-tropical Australia, crushing native species in its relentless advance.
