5 Questions
What is the principal rank of taxa in modern use?
The principal ranks in modern use are domain, kingdom, phylum (or division in botany), class, order, family, genus, and species.
What is taxonomy?
Taxonomy is the scientific study of naming, defining, and classifying groups of biological organisms based on shared characteristics.
Who is regarded as the founder of the current system of taxonomy?
The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy.
What is Linnaean taxonomy known for?
Linnaean taxonomy is known for developing a ranked system for categorizing organisms and binomial nomenclature for naming organisms.
How has the Linnaean system transformed with advances in biological systematics?
With advances in biological systematics, the Linnaean system has transformed into a more modern system of taxonomy.
Study Notes
Taxonomy
- The scientific study of naming, defining, and classifying groups of biological organisms based on shared characteristics
- Comes from Ancient Greek "taxis" meaning 'arrangement' and "-nomia" meaning 'method'
Taxonomic Hierarchy
- Organisms are grouped into taxa (singular: taxon) and given a taxonomic rank
- Groups of a given rank can be aggregated to form a more inclusive group of higher rank
Principal Ranks
- Domain
- Kingdom
- Phylum (division is sometimes used in botany in place of phylum)
- Class
- Order
- Family
- Genus
- Species
Carl Linnaeus
- Regarded as the founder of the current system of taxonomy
- Developed a ranked system known as Linnaean taxonomy for categorizing organisms
- Developed binomial nomenclature for naming organisms
Evolution of Taxonomy
- The Linnaean system has transformed into a modern system with advances in theory, data, and analytical technology of biological systematics
