Nature's response to urban growth DW Documentary

Recent discoveries add another surprising chapter to the theory of evolution. In our cities in particular, animals and plants adapt particularly quickly to their new living conditions. Nature's response to urban expansion is astonishing: Why do catfish in a French city's river systematically hunt pigeons on the banks? Why do female birds on a Californian university campus suddenly change their mating behaviour? How have mice in New York's Central Park adapted to a diet of human food waste? How did killifish in the Atlantic develop resistance to deadly chemical waste? And: Is it possible for moths to adapt to nighttime light pollution? New research provides surprising insights into Darwin's theory of evolution. Because nowhere else do animals and plants adapt to new living conditions as quickly as in cities. Biologists have long known that animals and plants occupy habitats close to humans. But now, new genetic analyses show that these adaptations are also based on significant changes in DNA – in other words, on evolution. And contrary to what was long believed, these changes do not occur over periods of thousands of years, but at lightning speed – within a few decades. Scientists are amazed at how nature manages to convert life-threatening human intervention – such as environmental pollution, light pollution, noise, waste and density in urban construction – into creative energy for new adaptations. Some researchers believe that our cities could soon develop their own ways of life. What are the consequences of this evolution for the balance between man and nature on our planet? #dwdocumentary #documentary ـــــ DW Documentary brings you information beyond the headlines.
