(from ancient greek: κλάδος, klados, “branch”)
.
*a clade is a group of ‘organisms’ that consists of a ‘common ancestor’ and all its ‘lineal descendants’ + represents a single “branch” on the “tree of life”*
.
(the ‘common ancestor’ may be an ‘individual’, a ‘population’, a ‘species’ (‘extinct’ or ‘extant’), and so on right up to a ‘kingdom’)
(‘clades’ are nested, one in another, as each ‘branch’ in turn splits into smaller branches)
(these splits reflect ‘evolutionary history’ as ‘populations’ diverged and evolved independently)
(‘clades’ are termed ‘monophyletic’ (greek: “1 clan”))
(over the last few decades, the ‘cladistic approach’ has revolutionized biological classification and revealed surprising evolutionary relationships among ‘organisms’)
.
(increasingly, ‘taxonomists’ try to avoid naming ‘taxa’ that are not ‘clades’) (that is, ‘taxa’ that are not ‘mono-phyletic’)
