Behavioral ecologists have observed clever copying behavior among many of our close animal relatives. One example was uncovered by behavioral ecologists studying the behavior of a small Australian animal called the quoll. Its survival was being (a)
threatened by the cane toad, an invasive species introduced to Australia in the 1930s. To a quoll, these toads look as tasty as they are (b)
poisonous, and the quolls who ate them suffered fatal consequences at a speedy rate. Behavioral ecologists identified a clever solution by using quolls’ instincts to imitate. Scientists fed small groups of quolls toad sausages containing harmless but nausea-inducing chemicals, conditioning them to (c)
avoid the toads. Groups of these ‘toad-smart’ quolls were then released back into the wild: they taught their own offspring what they’d learned. Other quolls copied these (d)
constructive behaviors through a process of social learning. As each baby quoll learned to keep away from the hazardous toads, the chances of the survival of the whole quoll species―and not just that of each individual quoll―were (e)
reduced. The quolls were saved via minimal human interference because ecologists were able to take advantage of quolls’ natural imitative instincts.
