Biodiversity, Systematics, and Modern Classification

TermDefinition
Biodiversity The variety of organisms considered at all levels, from population to ecosystems
Taxonomy The science of describing, naming, and classifying organisms
Kingdom In a traditional taxonomic system, the highest taxonomic category, which contains a group of similar phyla
Genus In a traditional taxonomic system, the category contained with a family and containing species
Species A group of organisms that are closely related and can mate to produce fertile offspring; also the level of classification below genus and above subspecies
Binomial Nomenclature A system for giving each organism a two-word scientific name that consists of a genus name followed by the species name
Subspecies A taxonomic classification below species that groups organisms that live indifferent geographical areas, differ morphologically from other populations of species, but can interbreed with other populations of the species
Systematics The classification of living organisms in terms of their natural relationships; it includes describing, naming, and classifying the organisms
Phylogenetics The analysis of evolutionary, or ancestral, relationships between taxa
Phylogenetic Diagram A branching diagram that models the relationships by ancestry between different species or other taxonomic groups
Cladistics A phylogenetic classification system that uses shared, derived characters and ancestry as the sole criterion for grouping taxa
Shared Character A feature that is shared by all members or a particular groups of organisms
Derived Character A feature that evolved only within a particular taxonomic group
Clade A taxonomic grouping that includes only a single ancestor and all of its descendants
Cladogram A diagram that is based on patterns of shared, derived traits and that sows the evolutionary relationships between groups of organisms
Eubacteria In a traditional taxonomic system, a kingdom that contains all prokaryotes except kingdom that contains all prokaryotes except Kingdom Archaebacteria (Domain Archaea); biologists more recently prefer to classify these organisms as Domain Bacteria
