OUR FACE FROM FISH TO MAN 



the fact that the right and left halves of my lower 

 jaw are composed of a single piece and that I 

 have a set of teeth limited to the margins of the 

 jaws and differentiated into incisors, canines, pre- 

 molars and molars. I also owe to these hitherto 

 much neglected animals the "basic patents" for 

 the delicate apparatus of my middle ear, together 

 with my bony palate and several other important 

 parts of my make-up. 



In the earliest mammals the bony mask became 

 covered with mobile, sensitive flesh; to them I 

 owe also the very hairs of my head, my eyebrows, 

 eyelashes and other facial accessories. 



To my earliest primate ancestors I owe the large 

 size of my eyes and a considerable part of my 

 brains. 



To my friendly anthropoid ancestors I am 



heavily indebted : for eyes that can focus on things 



near at hand, that give stereoscopic pictures and 



that follow closely the flight of a moving object; 



for a nose that is a real nose and not a snout; for 



lips that can smile and laugh or curl up in anger 



or kiss in love; from them I inherited all my baby 



teeth and my thirty-two adult teeth; the very 



shape of my ears is theirs.
