What is taxonomy?
Taxonomy is the science of classification, specializing in classifying organisms into groups called Taxa.
Taxa is the plural of Taxon, which refers to a single group in taxonomy.
Who is considered the father of taxonomy?
Carl Linnaeus is considered the father of taxonomy for creating Taxa and organizing living organisms based on similarities.
What are the seven Taxa in biological classification?
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
What is the largest taxon?
The largest taxon is Kingdom.
What is the smallest taxon?
The smallest taxon is Species.
What is the most diverse taxon?
Kingdom is the most diverse taxon.
What does the current tree of life show?
The current tree of life shows our most current understanding of biological classification.
What happened in 1866 regarding classification?
In 1866, all single-celled organisms were moved to kingdom Protista.
What significant change occurred in 1938?
In 1938, prokaryotes were moved to kingdom Monera.
What happened in 1959 in terms of classification?
In 1959, fungi were moved to their own kingdom.
What occurred in 1977 regarding kingdom Monera?
In 1977, kingdom Monera split into kingdoms Bacteria and Archaea.
What are the three domains in the tree of life?
- Bacteria
- Archaea
- Eukarya
What is the domain model based on?
The domain model was proposed by Carl Woese based on rRNA studies of prokaryotes.
What does Domain Bacteria include?
Domain Bacteria includes prokaryotes in the kingdom Bacteria.
What characterizes Domain Archaea?
Domain Archaea includes prokaryotes with cell walls chemically different from bacteria.
What does Domain Eukarya include?
Domain Eukarya includes all eukaryotes, including kingdoms Protista, Plantae, Fungi, and Animalia.
True or False: Bacteria and Archaea can be difficult to classify.
True.
