Systematics is the scientific study of how living things are classified and organized. It helps scientists understand the relationships between different species, including their evolutionary history. By grouping organisms based on shared characteristics, systematics provides a framework for identifying and naming species, which is essential for biological research and conservation efforts. One key aspect of systematics is the use of phylogenetic trees, which visually represent the evolutionary connections among species. These trees help researchers trace the lineage of organisms, such as plants and animals, and reveal how they have evolved over time. This understanding is crucial for biodiversity conservation and studying ecosystems.
