Phylogenetic invariants - Wikipedia
WEBPhylogenetic invariants. Phylogenetic invariants [1] are polynomial relationships between the frequencies of various site patterns in an idealized DNA multiple sequence alignment. They have received substantial study in the field of biomathematics, and they can be used to choose among phylogenetic tree topologies in an empirical setting.
Phylogenetics | SpringerLink
WEBPhylogenetics. Phylogenetics is a relatively young and rapidly growing subdiscipline of the much older and larger discipline known as systematics. There are three complementary subdisciplines within systematics: taxonomy, classification, and phylogenetics. While taxonomy is used to describe the Earth’s biodiversity through identifying ...
International Society for Phylogenetic Nomenclature
WEBWelcome to the website of the. International Society for Phylogenetic Nomenclature . The ISPN encourages the development and use of phylogenetic nomenclature and oversees the implementation of a code of rules to govern phylogenetic nomenclature — the PhyloCode . The society is open to anyone wishing to partake in this venture. Join the ISPN.
Primitive - Wikipedia
WEBPrimitive (phylogenetics), characteristic of an early stage of development or evolution. Primitive equations, a set of nonlinear differential equations that are used to approximate atmospheric flow. Primitive change, a general term encompassing a number of basic molecular alterations in the course of a chemical reaction.
Substitution model - Wikipedia
WEBSubstitution model. In biology, a substitution model, also called models of sequence evolution, are Markov models that describe changes over evolutionary time. These models describe evolutionary changes in macromolecules, such as DNA sequences or protein sequences, that can be represented as sequence of symbols (e.g., A, C, G, and T in the …
Cladogram - Wikipedia
WEBA horizontal cladogram, with the root to the left. Two vertical cladograms, the root at the bottom. A cladogram (from Greek clados "branch" and gramma "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants ...

WEBWebsite. www.phylonames.org. The International Society for Phylogenetic Nomenclature was established to encourage and facilitate the development and use of, and communication about, phylogenetic nomenclature. It organizes periodic scientific meetings and is overseeing the completion and implementation of the PhyloCode. [1] [2]
PHYLIP - Wikipedia
WEBPHYLogeny Inference Package. PHYLogeny Inference Package ( PHYLIP) is a free computational phylogenetics package of programs for inferring evolutionary trees ( phylogenies ).

Phylogenetic inertia - Wikipedia
WEBPhylogenetic inertia or phylogenetic constraint refers to the limitations on the future evolutionary pathways that have been imposed by previous adaptations. [1] Charles Darwin first recognized this phenomenon, though the term was later coined by Huber in 1939. [2] Darwin explained the idea of phylogenetic inertia based on his observations; he ...
Bootstrapping - Wikipedia
WEBIn computer technology, the term bootstrapping refers to language compilers that are able to be coded in the same language. (For example, a C compiler is now written in the C language. Once the basic compiler is written, improvements can be iteratively made, thus pulling the language up by its bootstraps).
