Deforestation changing animals

Human destruction of natural habitats and the impact this has on the animal and insect life they support has been well documented, and a new study from the University of Otago takes that impact a step further, providing the most clear cut evidence human activities like deforestation can drive evolutionary change within a species. Co-author Professor Jon Waters from Otago's Department of Zoology talks to Mihi about the significance of their discovery and why it isn't all bad news.
