Title: It's no wonder male orguntans have big cheeks Written by: duddy on Sep 2, 2015 (https://biology-forums.com/gallery/47/275816_26_01_15_5_23_38_20411842.jpeg) (https://biology-forums.com/index.php?action=gallery;sa=view;id=20413) Unlike most mammals, mature male orangutans exhibit different facial characteristics: some develop large 'cheek pads' on their faces (as shown above); other males do not. A team of researchers studied the difference in reproductive success between cheek-padded males and males without cheek pads. They found that those with cheek pads are significantly more successful in fathering offspring.
