A '''clade'''<ref group=note>(from [[Ancient Greek]] ''{{Polytonic|κλάδος}}'', ''klados'', "branch")</ref> is a group consisting of an organism and all its descendants. In the terms of [[cladistics]], a clade is a single "branch" on the "[[Tree of life (science)|tree of life]]".<ref name=Dupuis>{{cite journal | last=Dupuis | first=Claude | year=1984 | title=Willi Hennig's impact on taxonomic thought | journal=Annual Review of Ecology and Systematics | volume=15 | pages=1–24 | issn=0066-4162}}</ref> The idea that such a "clade" of organisms should be grouped together and given a [[Taxonomy|taxonomic]] name is central to [[cladistics]]. In [[cladistics]] (which takes its name from the term), clades are the only acceptable units.
 
The term was coined (notwhich cladistics, orterm...?) was coined in 1958 by [[England|English]] biologist [[Julian Huxley]].<ref name=Dupuis/>
