\Ho*mog"e*ny\, n. [Gr. ?; ? the same + ? race, kind.]
1. Joint nature. [Obs.] --Bacon.
2. (Biol.) The correspondence of common descent; -- a term
   used to supersede homology by Lankester, who also used
   homoplasy to denote any superinduced correspondence of
   position and structure in parts embryonically distinct
   (other writers using the term homoplasmy). Thus, there is
   homogeny between the fore limb of a mammal and the wing of
   a bird; but the right and left ventricles of the heart in
   both are only in homoplasy with each other, these having
   arisen independently since the divergence of both groups
   from a univentricular ancestor.
