Chapter 18 - Classification Flashcards
Who developed the system of Binomial nomenclature?
Carolus Linneaus
Linneaus system of naming organisms, which gives a scientific two-word Latin name to each species - the first part is the genus name and the second part is the specific epithet.
Binomial nomenclature
Named group of organisms, such as a phylum, genus, or species
Taxon
Group of organisms that can interbreed and produce fertile offspring
Species
Taxonomic group of closely related species with a common ancestor
Genus
Taxonomic group of similar, related genera that is smaller than an order and larger than a genus
Family
Taxonomic group that contains related families
Order
Taxonomic group that contains one or more related orders
Class
Taxonomic group of related classes
Phylum
Taxonomic group of related phyla or divisions
Kingdom
Evolutionary history of a species
Phylogeny
Diagram with branches that represent the hypothesized phylogeny or evolutionary species or groups
Cladogram
Morphological or biochemical feature found in one group of a line but not in common ancestors
Derived Character
Model that uses comparisons of DNA sequences to estimate phylogeny and rate of evolutionary change
Molecular clock
Functional unit that controls inherited trait expression that is passed on from on generation to another generation
Gene
