WebDerived characteristics are ones that establish groups / clades. Or an easy way to determine what a derived characteristic is what evolutionary change sets this group apart from others. In this case, lungs was the evolution that established them apart from fish. I was thinking of a convergent characteristic. elliebrolo • 3 yr. ago WebAncestral character states are sometimes called primitive; however, this term is misleading because it suggests that the ancestral state is less advanced than the derived state and … In phylogenetics, a primitive (or ancestral) character, trait, or feature of a lineage or taxon is one that is inherited from the common ancestor of a clade (or clade group) and has undergone little change since. Conversely, a trait that appears within the clade group (that is, is present in any subgroup within the clade but not all) is called advanced or derived. A clade is a group of organisms that consists of a common ancestor and all its lineal descendants. first pentecostal holiness church lumberton
