Listener Bart in Australia sees invasive species in his area almost every day – rabbits, foxes, and cats. They were transplanted to Australia from Europe more than 100 years ago, but seem to be thriving in their new home.
This got him wondering: how are they going to evolve, now that they are in a new habitat? Can we predict what future evolution will look like based on what we already know?
To find out, Marnie Chesterton visits Sandy Ingelby at the Australian Museum, who manages the mammal collection. She shows Marnie how indigenous Australian animals have evolved to suit where they live.
On the island of Tasmania, Marnie meets the famous Tasmanian Devil and keeper Jono Thomas. Andy Flies from the University of Tasmania explains how the devil is evolving in real-time in response to a health crisis.
So what might the invasive species in Bart’s backyard look like over the next 100 years? We’ll find out, with a little bit of help from palaeontologist Matt McCurry and millions of murderous toads.
