https://www.scientificamerican.com/article/speeding-up-evolution-to-save-an-australian-marsupial-from-toxic-toads/ > On an island off Australia’s north-central coast, researchers are conducting an unprecedented experiment: mixing endangered animals that have evolved genetic defences against their biggest foe with those that haven’t, in the hope that their offspring will take after the wiser parent. > The subject of the experiment is one of Australia’s most imperilled marsupials, the northern quoll (Dasyurus hallucatus). This squirrel-sized carnivore is struggling to survive a decades-long onslaught of poisonous and invasive cane toads, which quolls mistake as prey, with devastating results. The team now working on Indian Island has successfully tested the match-making technique in captive-bred quolls, and reported the results last month in Conservation Biology.
