Evolutionary ecology is a field of science that explores how the interactions between organisms and their environment can influence their evolution. Organisms are constantly adapting to their surroundings, and this study helps us understand how this adaptation occurs and why it matters. For example, different species of birds might have evolved different beak shapes to better suit the types of food they eat. This field also investigates how changes in the environment can drive evolution, such as when a new predator arrives or a habitat changes due to human activity.
