Fig. 3. Development of the Head, Fish to Man (contd.) 



The varieties of domesticated pigeons shown in Figure 1 were obtained 

 within a few centuries. These pictures visualize what probably happened 

 in 100,000,000 years. 



Man evolved from fish. Note how the mouth gradually recedes, until 

 it is below the eyes instead of in front of them. The nostrils move closer 

 together and the nose becomes more prominent. The monkey is the first 

 animal to develop a steeper forehead. (By courtesy of Life magazine.)
