  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Homogeny  \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. 
 
  From  WordNet  r  1.6  [wn]: 
 
  homogeny 
  n  :  (biology)  similarity  because  of  common  evolution
