A term used in phylogenetics (particualarly cladistics) to denote a
shared-derived character, that is, a character (say, feathers) that is
shared by members of a group and the closest common ancestor of that group,
but not shared by others outside of the group.  A synapomorphy can also be
called a "homologous character."
