Evolutionary research is the study of how species change and adapt over time through the process of natural selection. This field of study explores how genetic variations within populations lead to changes in traits, behaviors, and adaptations that help organisms survive and reproduce in their environments. Evolutionary research also examines the mechanisms driving evolution, such as genetic drift, gene flow, and mutation, as well as the patterns and processes of evolution at different scales, from the molecular level to ecosystems and beyond. This research area often involves a combination of theoretical and experimental approaches to understand the complexity and diversity of life on Earth.
