Discover how a range of animal species are rewriting the rules of evolution in just a few decades to survive the Anthropocene. Scientists discover animals evolving within just decades to survive humans and extreme climate conditions. However, the selective pressure exerted by global warming, extreme weather events and urbanisation has accelerated this biological clock, triggering what scientists describe as rapid eco-evolutionary dynamics. Here are some of the mechanisms through which the animal kingdom is rapidly evolving to survive on a planet undergoing constant climatic and environmental disruption. Faced with continuous and extreme environmental stress, wildlife populations encounter an urgent biological crossroads: adapt or perish.
