Biosystematic refers to the study of biological systems and processes, and it involves the identification, classification, and naming of organisms based on their physical and genetic characteristics. Synonyms for the term biosystematic include systematics, taxonomy, biological classification, and phylogenetics. Systematics is the scientific study of biological diversity and is concerned with the identification and classification of organisms based on similarities and differences in their physical and genetic traits. Taxonomy deals with naming, describing, and classifying organisms, while biological classification refers to grouping organisms based on their evolutionary relationships. Phylogenetics is the study of the evolutionary history and relationships of living organisms, typically represented in a diagram known as a phylogenetic tree.
