Evolutionary Biology focuses on the processes and patterns that drive changes in living organisms over time, with an emphasis on understanding genetic variation and how it contributes to adaptation. This field draws from both genetics and biotechnology, as it often involves the use of molecular techniques to study evolutionary relationships and mechanisms. In this hierarchy, Evolutionary Biology falls under Biotechnology, which encompasses the development and application of technology for the manipulation of biological systems, and Genetics, the scientific study of heredity and variation in organisms, as well as Science, the systematic study of the physical and natural world through observation and experiment. Researchers in this area may investigate topics such as speciation, phylogenetics, and molecular evolution to better understand the history of life on Earth and its future trajectories.
