Study Notes
Classification System
- Carolus Linnaeus introduced binomial nomenclature to systematically categorize all living organisms.
- Binomial nomenclature consists of a two-part scientific naming system for species.
Taxonomy Hierarchy
- The least specific classification category is domain, which encompasses the broadest range of life forms.
Shared Taxonomic Classifications
- Humpback whales (mammals) and basking sharks (fish) share the same classifications in domain, kingdom, and phylum, demonstrating the commonalities across different life forms.
Phylogenetic Trees and Dichotomous Keys
- Phylogenetic trees and dichotomous keys both serve to visualize and understand the taxonomic relationships among various organisms.
Identifying Plants with a Dichotomous Key
- A dichotomous key provides a systematic approach to identifying plants based on observable traits.
- In a practical example, a plant characterized by many broad leaves with rough edges is classified as Juglans nigra (black walnut).
