单词	clade
释义	clade /kleɪd / noun Biology A group of organisms believed to comprise all the evolutionary descendants of a common ancestor: the great ape and human clade... Species in the two primary clades in the genus tend to be found in different parts of North America. Fossils are often not ancestors of extant taxa, but instead may be extinct sister groups to modern taxa or clades. The same mode of increase has been adopted independently in phylogenetically distinct clades. Origin 1950s: from Greek klados 'branch'.
