what i'm saying, though, is that they wouldn't have to know the emotinal word 'cousin' to smell the incompatible genes. Well, that, or they happened to be compatible, in which case they most likely wouldn't get birth defects anyway.
Which is the exact thing that makes it acceptable.
Also, animals very much DO have societies. Also some animals DO inbreed, though, again, not always a good idea because _breeding_ isn't usually good with incest.
