Cane Toad Counterattack
Australians are mounting an effort to halt the spread of the toxic cane toad, an invasive species in Queensland, which has been killing native predators, including such large species as crocodiles. I'm predicting two things. First, the effort will not succeed. (I hope I'm wrong.) Second, the toads will undergo changes as a result of the extermination campaign. That is, new regimes of natural selection will filter subsequent generations of cane toads, promoting whatever characteristics they might have that make them less susceptible to being killed by humans. An example might be improved camouflage.
I have written previously on this topic here.
