This document provides an overview of taxonomy and how organisms are classified. It explains that taxonomy involves classifying organisms into a hierarchical system of groups from the broadest domain to the most specific species level. The key groups are domains, supergroups, kingdoms, phyla, classes, orders, families, genera and species. It also describes binomial nomenclature, the standard scientific naming convention where each species is identified by its genus and specific epithet.

1. Section 26.1 – Taxonomy By Lauren Banjo!

2. Taxonomy Classifying living and extinct organisms and viruses Hierarchy Easier for scientists to study if they're in groups Each group is called a taxon

3. Taxonomic Groups Domain Supergroup Kingdom Phylum Class Order Family Genus Species

4. Domain Largest and broadest groups There are 3 domains Bacteria Archaea Eukaryea

5. Differences Between Domains

6. Supergroup and Kingdom Domain Eukarya divided into 7 supergroups Animalia and Fungi under “Opisthokonta” Plantae under “Land plants and algal relatives”

7. Phylum, Class, Order, Family, Genus, and Species Taxons get progressively smaller and more specific The more specific, the similar the characteristics

8. Binomial Nomenclature Standard method for naming species First name is the Genus, second is a specific epithet Genus name is capitalized, epithet is not Both are italicized In the same passage, the second time it's mentioned, the Genus can be abbreviated Examples: Homo sapien (first mention) H. sapien (other mentions)

9. Can anyone name a species? Yes! There are rules to follow Rules are put in place by: International Commission on Zoological Nomenclature (ICZN) for animal species International Code of Botanical Nomenclature (ICBN) for plant species International Committee on Systematics of Prokaryotes (ICSP) for prokaryotes
