Explanation:
Character displacement is an evolutionary process in which the traits of two or more species diverge as a result of competition. This process is often observed in closely related species that live in the same geographic area and have similar ecological niches. In tundra, different organism populations have adapted to different environmental conditions, such as temperature, moisture, and food availability. This has led to the divergence of traits, such as body size, coloration, and behavior, between different populations. For example, some tundra animals have developed thick fur to insulate themselves from the cold, while others have developed long legs to help them navigate the snowy terrain.
