     • Identification: Providing a means to identify and distinguish different organisms.
   • Levels of Classification: Taxonomy involves hierarchical levels, including Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
2. Systematics:
   • Definition: Systematics is the broader field that encompasses taxonomy, and it involves studying the evolutionary relationships among organisms.
   • Goals:
     • Phylogenetics: Understanding the evolutionary history and relationships among different species.
     • Cladistics: Identifying and analyzing clades, which are monophyletic groups sharing a common ancestor.
     • Molecular Systematics: Using molecular data (DNA, RNA, proteins) to infer evolutionary relationships.
   • Methods: Systematists use various methods, including morphological, anatomical, behavioral, and molecular data, to reconstruct phylogenetic trees.

Key Points:

• Taxonomy is concerned with naming and classifying organisms.
