Study Notes
Taxonomic Categories
- Classification involves a hierarchical system, where each step represents a rank or category, known as a taxonomic category.
- All taxonomic categories together form a taxonomic hierarchy, essential for organizing biological classifications.
- Each taxonomic category corresponds to a rank, referred to as a taxon (plural: taxa).
- Insects serve as an example of a recognizable taxonomic group, identified by shared characteristics like three pairs of jointed legs.
- Categories are defined as distinct biological entities, and taxonomic studies have established common categories: kingdom, phylum/division (for plants), class, order, family, genus, and species.
- Species is the lowest taxonomic category for all organisms, representing a group of individuals with fundamental similarities.
Understanding Species
- A species consists of individual organisms that share morphological similarities and can be distinguished from closely related species.
- The distinct morphological differences among species help in classification, allowing the identification of different taxonomy levels.
- Examples of species include:
- Mangifera indica (mango)
- Solanum tuberosum (potato)
- Panthera leo (lion)
- The genus name (Mangifera, Solanum, Panthera) represents a higher taxonomic category, with specific epithets (indica, tuberosum, leo) indicating particular species within that genus.
- A genus may encompass multiple species that share common morphological traits, illustrated by Panthera containing both Panthera leo (lion) and Panthera tigris (tiger) as species.
