A new species of endemic frog discovered from fossils in North Canterbury has been named in recognition of the late Otago Professor Phil Bishop (1957–2021) for his worldwide services to amphibian ...

Evolution is the result of environmental pressures forcing species to adapt, and few environments exert pressures like the Chernobyl exclusion zone. A new study has revealed evolution in action as ...
