THE NEW EVOLUTION 



wandered through the forests. Unarmed, he is no 

 match for the great cats, wolves and other predacious 

 creatures which preyed upon these other mammals. 

 He is relatively slow of foot, and is a poor and inexpert 

 climber. And in addition to all this the young of 

 man are at first helpless and then dependent for many 

 years, while the human family consists of a series of 

 several or m.any of these helpless and dependent young. 



Feeble and frail of body, with helpless and depend- 

 ent young and the further handicap of a serial family, 

 man is the dominant living creature in the world 

 today by virtue of his extraordinary mental attributes. 

 Man must have an intellect superior to that of all 

 other living things because he has the maximum 

 number of liabilities to meet. 



In the insects, birds and rodents, and in a lesser 

 degree in other forms of life, we see foreshadowed here 

 and there, appearing in a curiously sporadic, isolated 

 and disconnected manner, many of the mental attri- 

 butes of man. But in man we find all of the mental 

 attributes found in all other living things combined, 

 together with greatly augmented curiosity, inventive- 

 ness and ingenuity. 



Is there a physical basis for the development of this 

 superior intellect in man? 



Strange as it may seem, one of man's greatest weak- 

 nesses appears to have been his greatest asset. For 

 the serial family of dependent young probably lies 

 at the base of all human societies and probably was 

 responsible for the development of human culture.
