Apomorphic
Definition
Possessing a derived trait or character, recently arisen during the phylogenetic evolution of a group of organisms and distinct from the primitive ancestral state; characteristic of modified anatomical structures or genetic sequences defining a new evolutionary branch. It constitutes the core element for establishing relatedness in modern cladistics, serving to differentiate taxa.
