(Polyphyly) (Greek for “of many races”)
1. Relating to or characterized by descent from more than one ancestral group. A polyphyletic group is a group whose members’ last common ancestor is not a member of the group. Polyphyly is a term in cladistics. It describes a group of organisms whose last common ancestor is not a member of the group. Another way of expressing this is to say that polyphyly includes groups some members of which are descended from ancestral populations.
