Phylogeny refers to the evolutionary history and relationships among different species or groups of organisms. It involves studying the similarities and differences in DNA sequences, physical characteristics, and other traits to determine how species are related and how they have evolved over time. The study of phylogeny is important in understanding the diversity of life on Earth, and in establishing classification systems that accurately reflect the evolutionary relationships among organisms. Phylogenetic trees, which show the branching patterns of species over time, are a common tool used in the study of phylogeny.
