The Preparation for Higher Life 



its creatures as a means of defense against their enemies. 

 Some of the insects and animals developed spines and quills, 

 scales and stings. The crabs developed a protecting armour 

 and the moUusks, oysters and shellfish of all kinds developed 

 a process of extracting lime from the water and forming it 

 into shells of beautiful designs and coloring as a protective 

 home in which to live. The more active insects developed 

 speed of legs and wings with which they might escape their 

 enemies. The law of the sea as well as the law of the jungle 

 is that the most cunning as well as the swiftest and most 

 powerful shall survive. In order to outwit their stronger 

 and more powerful enemies, it was necessary that a sensitive 

 system of body communication be established and that this 

 system be centered in a directing brain. From this brain 

 messages must be sent to all the various parts of the body 

 and in turn all the various organs of the body must be guided 

 in their functions by the brain. 



It was destined that the nerve centers were to play the 

 greatest part in evolutionary growth. Throughout all of 

 life's history covering a period of many millions of years 

 this process of developing a nerve system had been going 

 on. A central nerve center, first a knot or ganglion, had 

 developed into a rudimentary brain. Its importance in the 

 scheme of life demanded of it greater duties and the highest 

 degree of protection. It was also necessary that the center 

 of this nerve system be connected with a conductor reaching 

 to all parts of the animal organism and that this conductor 

 be equally protected against injury in order to properly per- 

 form its functions. This led to what is commonly called the 

 *'next great step" in evolutionary progress — that of pass-
