A Story Outline of Evolution 



reproduce their kind are ever present. The class as a whole 

 begins to climb higher in the scale of animal life. Some take 

 one road and some another. Some of these fall by the way- 

 side and their types no longer survive. All encounter diffi- 

 culties but the procession moves on each shaping its body by 

 adaptations to aid it in its struggles for existence. Some 

 develop claws and teeth, some long legs and fleetness of foot, 

 some horns, some spines and some brains as aids in securing 

 food and as a means of self-protection against their enemies. 



It was ordained from the beginning that brain power, 

 the force of reason, should rule and have dominion over all 

 the creatures of the earth. Several families of the 10,000 

 species of this class began to rely on mental action more than 

 on muscle, tooth and claw action as a means of securing food 

 and as a means of self-protection. Mental action called for 

 an increase in the size of the brain and as a consequence, the 

 families that increased the size of the brain emerged from 

 the crowd and climbed a step higher than all the rest. 



The last and highest order of mammals that have 

 advanced to a higher step above all others is the order that 

 has developed the largest brain. Included in this order are 

 the lemurs, monkeys and man. The anthropoid apes such 

 as the gibbon, orangutan, gorilla and chimpanzee have 

 reached the step next to the top in the ascent of life but man 

 has outdistanced all of these and has reached the topmost 

 step in the scale of life. The brain of the lowest type of man 

 is twice the size of that of the highest ape. By developing 

 a brain greater in size than all the others and by developing 

 the power of speech, man has attained the position where he 

 has dominion over all the other creatures of the world. With
