Evolutionary Biology is the study of how life evolves over time through processes like natural selection, genetic drift, mutation, and gene flow. This field explores the origins of species, the relationships among them, and the genetic and environmental forces that drive diversity and adaptation. From the emergence of antibiotic resistance to the evolution of complex traits, evolutionary biology offers insights into the fundamental mechanisms that shape life on Earth. Cutting-edge research in this field helps scientists understand everything from ancient fossils to rapidly evolving viruses, bridging the past, present, and future of life.
