A Story Outline of Evolution 



the first Implement used by man, has developed Into the 

 knives of Industry ranging from the pocket knife to every 

 steam and electrical knife In use. 



His body was covered with a heavy coat of hair that 

 gave to him protection from the cold. Long centuries after 

 he had learned to make and use Implements of stone, a great 

 climatic change came over the Northern Hemisphere. 

 Great glaciers of Ice came slowly moving southward. The 

 tropical regions of Alaska that produced the great beds of 

 coal that are found there were changed to fields of Ice 

 moving southward, carrying, rolling, grinding and smooth- 

 ing pieces of broken granite Into sand and boulders. These 

 great Ice movements move southward In America to a point 

 as far south as the Ohio River, dropping their granite and 

 rock boulders along their way. They completely changed 

 ancient rivers and. In their stead, formed new ones that 

 flowed In altogether different directions. The main body 

 of this great Ice floe In America found a resting place along 

 the northern boundary of the United States where they 

 melted and formed the Great Lakes. The same conditions 

 were true In Europe. As the great Ice floes came moving 

 southward, there was the great migration of animal life 

 toward the warmer climate where food could be found. 

 Primitive man either remained or followed back his steps 

 as the Ice receded by melting. Evidence Is conclusive that 

 climatic conditions changed and that man and many of the 

 animals adapted themselves to the changed conditions. In 

 doing this, he sought the shelter of limestone caverns and 

 other shelters and made use of animal skins for clothing.
