|
Biodiversity |
the variety of life in the world or in a particular habitat or ecosystem. |
|
|
Taxonomy |
the branch of science concerned with classification, especially of organisms; systematics. |
|
|
Taxon |
a taxonomic group of any rank, such as a species, family, or class. |
|
|
Kingdom |
a taxonomic category of the highest rank, grouping together all forms of life having certain fundamental characteristics in common: in the five-kingdom classification scheme adopted by many biologists, separate kingdoms are assigned to animals (Animalia), plants (Plantae), fungi (Fungi), protozoa and eucaryotic algae ... |
|
|
Bionomial Nomenclature |
the system of nomenclature in which two terms are used to denote a species of living organism, the first one indicating the genus and the second the specific epithet. |
|
|
Subspecies |
a taxonomic category that ranks below species, usually a fairly permanent geographically isolated race. Subspecies are designated by a Latin trinomial |
|
|
Systematics |
the branch of biology that deals with classification and nomenclature; taxonomy. |
|
|
Phylogenics |
the branch of life science concerned with the analysis of molecular sequencing data to study evolutionary relationships among groups of organisms. |
|
|
Phylogenetic Diagram |
a branching diagram or "tree" showing the inferred evolutionary relationships among various biological species or other entities—their phylogeny—based upon similarities and differences in their physical or genetic characteristics. |
|
|
Cladistics |
a method of classification of animals and plants according to the proportion of measurable characteristics that they have in common. It is assumed that the higher the proportion of characteristics that two organisms share, the more recently they diverged from a common ancestor. |
|
|
Shared Character |
a trait that is shared ("symmorphy") by two or more taxa and inferred to have been present in their most recent common ancestor, whose own ancestor in turn is inferred to not possess the trait. |
|
|
Derived Character |
A group that does not include the common ancestor of the group. The common ancestor is placed in another group. Out Group: A group outside the groups in question which is used to define the polarity ofcharacter transformations (primitive to derived). |
|
|
Clade |
a group of organisms believed to have evolved from a common ancestor, according to the principles of cladistics. |
|
|
Cladogram |
a branching diagram showing the cladistic relationship between a number of species. |
