Horn's Revenge

Horn's Revenge is a concept in evolutionary biology describing how a trait that was initially beneficial for survival or reproduction can later become a disadvantage, prompting a counter-adaptation. Think of it like a "double-edged sword"—an adaptation that helps in one way but creates new challenges. Over time, species may develop complex responses to balance these effects, leading to ongoing evolutionary "arms races." Essentially, Horn's Revenge illustrates how evolutionary advantages can sometimes backfire, resulting in new pressures that drive further adaptations.
