Key species in evolutionary biology

Key species in evolutionary biology are organisms that play a crucial role in shaping the diversity and structure of ecosystems through their interactions, adaptations, or impact on other species. They influence the environment or other species significantly, often serving as indicators of ecological health. Examples include keystone predators that control prey populations or foundational species like corals that create habitats. Studying key species helps scientists understand how organisms and ecosystems evolve, adapt, and maintain stability over time, highlighting their importance in the web of life.
