比较了一系列兽孔目动物和早期哺乳动物的下颌和下颌肌肉组织。它示出了如何在结构的变化tne下颌和插入的下颌肌肉逐渐减少的力量，其中下颌关节受到在咬。这些变化使得爬行动物下颌关节（方骨和关节骨）和其他附属颌骨的大小减少，而齿骨的大小增加。
The lower jaws and jaw musculature of a series of therapsids and early mammals are compared. It is shown how changes in the structure of tne lower jaw and insertions of the jaw muscles progressively reduced the forces to which the jaw joint was subjected during biting. These changes made it possible for the bones forming the reptilian jaw joint (quadrate and articular) and other accessory jaw bones to decrease in size while the dentary increased in size.
