Study Notes
Taxonomy and Classification
- The next closest relationship after species is indicated by the genus.
- Humans are specifically classified as Homo sapiens.
- Taxonomic categories progress from general to specific starting from the kingdom level.
Classification of Organisms
- Sharks and humans are classified in the same phylum due to both possessing spinal cords.
- Latin is used in scientific naming because it is unchanging, being a "dead" language.
Modern Classification Systems
- Organisms are grouped into five kingdoms:
- Protista (example: Amoeba)
- Fungi (example: Mold)
- Plantae (example: Mosses)
- Animalia (example: Man)
- Monera (example: Bacteria)
- In the binomial system of nomenclature, the scientific name is comprised of the species and genus.
Taxonomy Order
- The correct order of taxonomy is: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
- The binomial name Canis lupus indicates the organism belongs to the genus Canis and the species lupus.
Historical Perspectives
- The binomial system for naming organisms was developed by Carolus Linnaeus.
Organism Characteristics
- A unicellular microorganism without an organized nucleus is classified as prokaryotic.
- Organisms that are single-celled and contain chloroplasts, a nucleus, and cytoplasm likely belong to the kingdoms of Bacteria or Archaea.
- Animals with a spinal column fall under the classification of Chordata.
Classification Relationships
- Taxonomic categories that show the most distant relationships include chordata.
- If an organism is named Proteus vulgaris, it reflects its classification in both domain and kingdom.
