Study Notes
Classification System
- A framework used by biologists for studying life’s diversity, naming organisms, and logically organizing them.
Taxonomy
- The scientific study concerned with classifying organisms and assigning universally accepted names.
Carolus Linnaeus
- A Swedish botanist recognized for creating binomial nomenclature, a two-word naming system for species.
Binomial Nomenclature
- Each species gets a two-part scientific name; the first word is capitalized (genus) and the second is lowercase (specific description). Example: Ursus maritimus.
LSC (Linnaeus' System of Classification)
- This system categorizes organisms based on structural similarities and operates within a hierarchical structure consisting of seven levels, from broadest to most specific.
Kingdom
- The most inclusive and largest category in Linnaeus's taxonomy, providing the broadest description of an organism.
Phylum
- Represents a category that includes multiple organisms sharing significant characteristics; phyla collectively create kingdoms.
Class
- Comprises groups of similar orders; multiple classes exist within a phylum.
Order
- A broader category made up of similar families; orders are subdivisions of classes.
Family
- Contains genera that exhibit shared traits, forming a constituent of orders.
Genus
- Encompasses closely related species and is the first part of the binomial nomenclature.
Species
- Defined as a population of organisms with similar traits capable of breeding to produce fertile offspring.
Cladistic Analysis
- A method for identifying and analyzing characteristics that evolve in organisms over time.
Derived Characteristics
- Features that have emerged in recent parts of evolutionary lineage, differing from those of older ancestors due to mutations and evolutionary change.
Cladograms
- Diagrams that utilize derived characteristics to illustrate the evolutionary relationships among groups of organisms.
