the reason for this is that it is easy for a person to direct the hole of his ear in all directions in order to facilitate the movement of his head for this and this is not the case for other livestock and the like. likewise every animal that has a prominent ear other than a person has its ears on top of its head in order to lower its head especially when grazing and the like unlike a person whose ears are in the middle of the sides of his head because it is easy for a person to move his head in all directions.
وسبب ذلك أن الإنسان يسهل عليه توجيه ثقب أذنه إلى جميع الجهات لأجل سهولة حركة رأسه لذلك ولا كذلك غيره من الماشية ونحوها، وكذلك كل حيوان له أذن بارزة غير الإنسان فإن أذنيه تكونان فوق رأسه وذلك لأجل طأطأة رأسه خاصة عند المرعى، ونحو ذلك بخلاف الإنسان فإن أذنيه في وسط جانبي رأسه وذلك لأن الإنسان يسهل عليه تحريك رأسه إلى جميع الجهات.
