Study Notes
Classification Levels
- Seven classification levels are: kingdom, phylum, class, order, family, genus, and species.
- Memorization sentence: "King Phillip Came Over For Good Spaghetti."
Scientific Naming
- Scientific names consist of two parts: Genus (general group) and Species (specific descriptor).
- The format for scientific names includes the first word capitalized, the second word in lowercase, and both words italicized.
Classification Characteristics
- Descending from kingdom to species increases specificity while decreasing the number of organisms.
- Ascending from species to kingdom results in a broader classification but includes increasingly more organisms.
Comparative Relationships
- Phylum contains more organisms than order.
- Organisms within the same order are more closely related than those in the same phylum.
Examples of Relationships
- Didelphis virginiana and Pinus virginiana are less closely related than Pinus virginiana and Pinus taeda.
- Ursus maritimus and Ursus americanus share the same genus, indicating a close relationship despite being different species.
