Study Notes
Hierarchical System of Classification
- Involves organizing species based on shared characteristics into more inclusive categories.
- Similar species are classified into a common genus, which is then part of a larger family.
Main Steps of the Hierarchical System
- Classification follows an ascending order:
- Species
- Genus
- Family
- Order
- Class
- Phylum
- Kingdom
- Domain
Taxonomic Conventions Example
- Taxonomic examples illustrate classification:
- Kingdom Animalia:
- Phylum (P): Arthropoda
- Class (C): Trilobites
- Order (O): Nectaspida
- Family (F): Emucaridae
- Genus (G): Emucaris
- Species (S): Emucaris fava
- Kingdom Plantae:
- Phylum (P): Bryophyta
- Class (C): Bryopsida
- Order (O): Bryates
- Family (F): Bryaceae
- Genus (G): Acidodontium
- Species (S): Acidodontium brachypodium
- Kingdom Animalia:
Grouping Organisms into Taxa
- Organisms are grouped based on shared characteristics.
- Fossils, homologous structures, and vestigial structures aid in classification.
- Physical and behavioral traits, such as eating habits, are also considered in taxonomy.
