The article you link states regarding Rh factors:
"antibodies to Rh+ blood in the woman which typically attack the blood of her subsequent Rh+ children, causing them to miscarry, be stillborn, or die shortly after birth (infant haemolytic disease [6]). This phenomenon is unknown elsewhere in nature..."
This type of blood antibody reaction is known to occur in other animals. And only a very few other animals have been studied for this. So it is possible that this occurs in many animals other than humans.
