A group showing similar traits that are different from other descendants of a common ancestor is called CLADE. It is the most inclusive group within a phylogeny.
A clade is a group of organisms that represent all descendants of a shared common ancestor and such ancestor in a phylogeny.
The organisms in a clade may show similar phenotypic traits, which only can be shared by the member of the clade and its common ancestor.
The most inclusive (and similar) traits in a clade are not shared with any other organism found outside the clade.
