Evolutionary genomics is a field of study that combines principles of genetics and evolution to understand the genetic changes that drive the adaptation and evolution of species over time. Researchers in this field use genomics technologies, such as DNA sequencing, to study how genes and genomes have evolved within and between species, and how they contribute to differences in traits and behaviors. By comparing the genetic sequence of different species, evolutionary genomics helps shed light on the patterns and processes underlying evolution and the diversification of life on Earth.
