Phylogenomics is a field of study that combines molecular biology and genomics to investigate the evolutionary relationships between organisms. By analyzing the genetic content of different species, researchers can construct phylogenetic trees that depict the evolutionary history and relatedness of different organisms. This approach allows for a more comprehensive understanding of evolutionary relationships than traditional methods based solely on morphology or behavior. Phylogenomics has applications in a wide range of fields, including evolutionary biology, biodiversity conservation, and drug discovery.
