Evolutionary biology is a scientific discipline that studies the processes and patterns of evolution in living organisms. This field explores how species originate, diversify, and change over time, often through the mechanisms of natural selection, genetic drift, and mutation. Evolutionary biologists use a combination of genetics, paleontology, ecology, and other fields to understand the history of life on Earth and predict how organisms may evolve in the future. This research area is crucial for understanding the biodiversity of life, the relationships between different species, and the impact of environmental changes on living organisms.
