monophyletic
Technical term in biology and phylogenetics, describing a group of organisms that includes an ancestor and all of its descendants.
It was confirmed that this taxon is monophyletic.
To define a monophyletic group, it is necessary to identify a common ancestor.
側系統 (paraphyletic) includes a common ancestor but not all of its descendants, unlike 単系統 which includes all descendants.
Compound of 単 (single) and 系統 (lineage, system), likely a calque from Western scientific terminology such as 'monophyletic'.
