 for Homogeny
From The Collaborative International Dictionary of English v.0.48 :

  Homogeny \Ho*mog"e*ny\, n. [Gr. ?; ? the same + ? race, kind.]
     1. Joint nature. [Obs.] --Bacon.
        [1913 Webster]
  
     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.
        [1913 Webster]

From WordNet (r) 3.0 (2006) :
