*** WHAT'S COVERED ***
1. The Need for Classification
* Traditional methods based on appearance and their limitations.
* Issues with common names and indicating relationships.
2. The Linnaean System
* Developed by Carl Linnaeus based on characteristics and structure.
* Hierarchical classification: Kingdom, Phylum, Class, Order, Family, Genus, Species.
3. The Binomial Naming System
* Using Genus and Species for unique, two-part Latin names (e.g., Homo sapiens).
4. Developments in Classification
* Impact of improved microscopes and understanding internal structures.
5. The Three-Domain System
* Developed by Carl Woese based on RNA sequence analysis.
* Domains: Archaea, Bacteria, Eukaryota (added above Kingdom level).
* Characteristics of each domain.
6. Evolutionary Trees
* How they show evolutionary relationships between species.
* Understanding common ancestors.
* Basis in structural comparison, DNA analysis, and fossil records.
7. Remembering the Order
* Mnemonic for the classification hierarchy.
