The evolutionary history of a species or team of associated species.

You are watching: The evolutionary history of a group of organisms is called a:

SystematicsA scientific technique focused on classifying organisms and also determining their evolutionary relationships.
TaxonomyA scientific discipline involved with naming and also classifying the diverse forms of life.
BinomialThe two-part, latinized format for naming a species, consist of of the genus and specific epithet; a binomen.
FamilyIn Linnaean classification, the taxonomic category over genus.
OrdersIn Linnaean classification, the taxonomic category over the level of family.
ClassIn Linnaean classification, the taxonomic category over the level of order.
PhylumIn Linnaean classification, the taxonomic category over class.
KingdomsA taxonomic category, the 2nd broadest after ~ domain.
Domain(1) A taxonomic category over the kingdom level. The three domain names are Archaea, Bacteria, and Eukarya. (2) A discrete structural and functional region of a protein.
Phylogenetic TreeA branching diagram the represents a hypothesis around the evolutionary history of a team of organisms.
PhyloCodeProposed system of classification of organisms based upon evolutionary relationships: Only groups that encompass a usual ancestor and all of its descendants are named.
Branch PointsThe representation on a phylogenetic tree that the divergence of 2 or an ext taxa from a typical ancestor. A branch suggest is usually presented as a dichotomy in which a branch representing the ancestral lineage splits (at the branch point) right into two branches, one for each the the 2 descendant lineages.
Sister TaxaGroups of organisms that share an immediate typical ancestor and also hence are each rather closest relatives.
RootedDescribing a phylogenetic tree that includes a branch suggest (often, the one farthest to the left) representing the many recent typical ancestor of every taxa in the tree.
Basal TaxonIn a specified team of organisms, a taxon whose evolutionary family tree diverged beforehand in the history of the group.
PolytomyIn a phylogenetic tree, a branch allude from which much more than two descendant taxa emerge. A polytomy suggests that the evolutionary relationships in between the descendant taxa are not however clear.
AnalogySimilarity between two varieties that is due to convergent advancement rather than to descent from a common ancestor through the exact same trait.
HomoplasiesA similar (analogous) framework or molecular sequence that has advanced independently in 2 species.
Molecular SystematicsA scientific discipline that uses nucleic mountain or other molecules to infer evolutionary relationships in between different species.
CladisticsAn method to systematics in which biology are inserted into groups called clades based mostly on typical descent.
CladesA team of types that includes an ancestral species and every one of its descendants.
MonophyleticPertaining to a team of taxa that is composed of a typical ancestor and every one of its descendants. A monophyletic taxon is equivalent to a clade
ParaphyleticPertaining to a team of taxa that is composed of a common ancestor and also some, yet not all, of its descendants.
PolyphyleticPertaining to a group of taxa derived from 2 or much more different ancestors.
Shared ancestral CharacterA character, mutual by members the a certain clade, that originated in one ancestor that is not a member of that clade.
Shared acquired CharacterAn evolution novelty the is distinctive to a specific clade.
OutgroupA species or team of types from one evolutionary family tree that is known to have actually diverged prior to the family tree that consists of the group of varieties being studied. One outgroup is selected so the its members are closely related come the team of species being studied, yet not as very closely related as any type of study-group members space to each other.
IngroupA varieties or team of species whose evolutionary relationship we look for to determine.
Maximum ParsimonyA rule that claims that once considering multiple explanations for an observation, one should very first investigate the easiest explanation the is regular with the facts.
Maximum LikelihoodAs applied to molecular systematics, a principle that states that once considering many phylogenetic hypotheses, one must take into account the theory that mirrors the most most likely sequence of evolution events, given certain rules about how DNA transforms over time.
Orthologous GenesHomologous genes that are discovered in different varieties because of speciation.
Paralogous GenesHomologous gene that are uncovered in the very same genome as a an outcome of gene duplication.
Molecular ClockA method for estimating the time forced for a offered amount of evolutionary change, based upon the observation that some regions of genomes evolve at constant rates.
Neutral TheoryThe hypothesis that much evolutionary adjust in genes and also proteins has no impact on fitness and also therefore is not affected by herbal selection.
Horizontal Gene TransferThe transport of gene from one genome to one more through instrument such together transposable elements, plasmid exchange, famous activity, and perhaps fusions of different organisms.
