فيمكنكم ملاحظة انك اذا وجدت واحداً والذي يكون قد نما بنسبة 80 في المائة ولم تكن تعرف انه سوف ينمو ليصبح طائر الكاسوراي فسوف تظن انهما حيوانان مختلفان
So you can see that if you actually found one that was 80 percent grown and you didn't know that it was going to grow up to a cassowary, you would think they were two different animals.
