The process by which living organisms adapt to their environment over generations is called evolution. Through the mechanism of natural selection, advantageous traits become more prevalent in a population over time, as organisms better suited to their environments are more likely to survive and reproduce. Adaptations can manifest in various forms, including physical traits, behaviors, and physiological processes. Evolution is driven by genetic variations introduced through mutations, gene flow, and genetic drift. Understanding evolution is crucial for comprehending biodiversity, species interactions, and responses to environmental changes. It is a fundamental concept in both biology and ecology.
