Definition of clade in English:
A group of organisms believed to have evolved from a common ancestor, according to the principles of cladistics.
- 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.
1950s: from Greek klados 'branch'.
