Study Notes
Classification Overview
- Modern classification hierarchy primarily established by Carl Woese.
- Taxonomy is the science focused on classifying and naming organisms based on characteristics.
Key Contributions to Classification
- Robert Whittaker introduced a five-kingdom system, expanding beyond the traditional two kingdoms of plants and animals.
- Linnaeus enhanced classification with the binomial naming system, categorizing organisms by genus and species.
Classification Systems and Changes
- Aristotle initially divided organisms into two kingdoms: Plants and Animals.
- Whittaker's system included three additional kingdoms: Fungi, Protista, and Monera.
- The Monera kingdom was further divided by Woese into Bacteria and Archaea.
Hierarchical Structure in Classification
- The classification system operates on eight levels, organized from broadest to most specific:
- Domain
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
Specific Examples
- The bald eagle is classified under:
- Kingdom: Animals
- Genus: Haliaeetus
- Species: leucocephalus
Summary of Classification Goals
- The primary objective of classification is to systematically organize organisms based on shared characteristics and relationships.
