systematics
Organism relationship study
Systematics is the scientific study of the diversity of organisms and their evolutionary relationships.
The field encompasses classification, naming, and organizing living things into hierarchical groups based on shared characteristics and common ancestry.
Molecular systematics has revolutionized our understanding of how species are related.
The term often overlaps with taxonomy, though systematics emphasizes evolutionary history while taxonomy focuses more on classification schemes.
