Blutongues (image) University of Chicago Press Journals Caption Bluetongue lizards from tropical Australia like the Darwin specimen to the left die if they eat an invasive cane toad, whereas members of the same lizard species from southern Australia like the Sydney specimen to the right are very resistant to the toad's poison. That tolerance seems to be due to rapid evolution brought about by the presence of a toxic garden plant that has almost identical poisons to cane toads.
