Flashcards in Classification Deck (20):
process by which scientists group living organisms
is the science of defining and naming groups of biological organisms on the basis of shared characteristics.
system of nomenclature in which each species of animal or plant receives a name of two terms of which the first identifies the genus to which it belongs and the second the species itself.
a taxonomic group of any rank, such as a species, family, or class.
A taxonomic category ranking used in biological classification that is below a family and above a species level, and includes group(s) of species that are structurally similar
is one of the eight major taxonomic ranks; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks above the rank of genus.
taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. Other well-known ranks are life, domain, kingdom, phylum, class, family, genus, and species, with order fitting in between class and family.
a taxonomic rank. descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class fitting between phylum and order.
A group of Classes with similar distinctive characteristics
division refers to a rank equivalent to phylum.
The highest classification into which living organisms are grouped
also superkingdom or empire, is the highest taxonomic rank of organisms
The evolutionary development and history of a species or higher taxonomic grouping of organisms
any observable feature, or trait, of an organism, whether acquired or inherited.
is a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged
A system of classification based on the phylogenetic relationships and evolutionary history of groups of organisms, rather than purely on shared features
a branching diagram showing the cladistic relationship between a number of species.
Any of the unicellular microorganisms that is genetically distinct from bacteria and eukaryotes, and often inhabiting extreme environmental conditions
eukaryotic organisms that cannot be classified as a plant, animal, or fungus
