    Study Notes

    Classification and Taxonomic Hierarchy

    • Classification is a hierarchical process involving multiple steps, with each step representing a rank or category.
    • The category is part of the overall taxonomic arrangement and is referred to as a taxonomic category.
    • All categories together constitute the taxonomic hierarchy.

    Taxonomic Categories and Ranks

    • Each category is a unit of classification and is commonly termed as a taxon (plural: taxa).
    • Taxonomic categories denote ranks, and each rank represents a unit of classification.
    • Examples of taxonomic groups/categories include insects, which are recognizable concrete objects that can be classified.
    • Other groups of organisms with common features can also be classified into categories.

    Characteristics of Taxonomic Categories

    • Taxonomic categories are distinct biological entities, not merely morphological aggregates.
    • These categories are based on the knowledge of characters of an individual or group of organisms, which helps in identifying similarities and dissimilarities among organisms.

    Taxonomic Hierarchy

    • The taxonomic hierarchy includes common categories such as:
      • Kingdom
      • Phylum or division (for plants)
      • Class
      • Order
      • Family
      • Genus
      • Species (the lowest category)
    • All organisms, including those in the plant and animal kingdoms, have species as the lowest category.
