(mon-oh-fy-leh-tik) Pertaining to a taxon derived from a single ancestral species that gave rise to no species in any other taxa.

Term applied to a group of organisms which includes the most recent common ancestor of all of its members and all of the descendants of that most recent common ancestor. A monophyletic group is called [..]

A taxonomic unit comprising a single clade

Refers to a taxon, phylogenetic tree, or gene tree whose members are all derived from a common ancestral taxon. In cladistic taxonomy, the term describes a taxon consisting of all the known species de [..]

derived from a single ancestral line. cf. polyphyletic.

A group composed of a collection of organisms, including the most recent common ancestor of all those organisms and all the descendants of that most recent common ancestor. A monophyletic taxon

Describes a set of taxa that all descend from a common ancestral taxon—that is, a group of organisms or genes

a taxonomic group consisting of a single common ancestor and all its descendants.

A group composed of a collection of organisms, including the most recent common ancestor of all those organisms and all the descendants of that most recent common ancestor. A monophyletic taxon is als [..]

A set consisting of an ancestor and all of its descendants; usually used for groups the members of which share a more recent common ancestor with one another than with any non-members, though monophyl [..]

Referring to a group of organisms with a single, common ancestor, and containing all descendants within that group.

Refers to a group of species that all have a single common ancestral species

Originally coined by Haeckel to refer to a group of organisms that is descended from its most recent known or inferred common ancestor (Haeckel, 1866). A monophyletic group in this traditional sense of the word may include all or only a part of the descendants of the common ancestor, and the ancestor may be a taxon of various ranks (Mayr & Ashl [..]

Having a unique common ancestor. A monophyletic taxonomic group traces it origins to a single ancestral species and includes that species and all species descended from it. This contrasts with a paraphyletic group, which includes a common ancestor but not all of its descendents, and a polyphyletic group, which does not include the group's most [..]

A taxonomic group is monophyletic if it consists of a common ancestor and all its descendants.

Refers to a taxon, or a branch of a phylogenetic tree or gene tree, that includes all the species (or genes) that descended from a common ancestor. Cf. paraphyletic, polyphyletic.
