A Story Outline of Evolution 



chambered heart, threw off the egg-laying process of repro- 

 ducing their kind, changed their scales to hair, gave birth to, 

 suckled and cared for their young and became mothers. 

 These new creatures began to develop and to increase their 

 brains to guide them in their struggles for existence. They 

 began to disburse and to adapt themselves to their surround- 

 ings and to seek out food for their sustenance. 



The greatest factor in developing the vast numbers of 

 different animal forms is that of selecting food. As a par- 

 ticular food was selected by one of these creatures to nourish 

 and sustain its family. Nature changed the form of its body 

 and developed its body organs so that the particular food 

 thus selected might be more easily obtained. If this par- 

 ticular food gave out or if another kind of food was selected, 

 Nature again shaped its body form and body organs so that 

 it might secure and utilize the new diet in the most economi- 

 cal manner. The shape, bones, teeth, skin, claws and mus- 

 cles of each species were thus developed and changed. 



The ground mole chose to burrow in the ground and to 

 live on grubs and worms. Nature developed its huge paddle 

 shaped clawed forefeet for digging its way through the soil. 

 Nature had given to it eyes but since it forsook the beauty 

 of day and the pleasure of seeing. Nature has robbed it of 

 its eyes which are now of its own choosing useless and rudi- 

 mentary. The giraffe and its immediate ancestors devel- 

 oped a liking for the tender top branches of the trees in its 

 surrounding and Nature aided it by developing for its use 

 long legs and a long neck so that these sought after tender 

 top branches might be more easily secured and with the least 

 effort. The giraffe's long neck has exactly the same num-
