Functional morphology is a research area within biology that focuses on studying the relationship between an organism's form and its function. This field examines how the anatomical structures of organisms are adapted to perform specific functions, such as for locomotion, feeding, or reproduction. Researchers in functional morphology often use a combination of anatomical, biomechanical, and ecological approaches to understand how the morphology of organisms has evolved to meet the demands of their environment and lifestyle. This research can provide valuable insights into evolutionary patterns and adaptations in various species.
