The Preparation for Higher Life 



to continue In their "struggle for existence/' Some of these 

 water animals became land Insects with hinged joints and 

 wings to aid them In their locomotion. They had legs with 

 which to walk, eyes with which to see, and wings with which 

 to fly, and a nervous system controlling their sensations but 

 still they were Invertebrates. 



Nature's method of adaptation to meet changing con- 

 ditions, always was, now Is, and always will be the same. 

 If a limb be cut from a willow tree and the cut end stuck 

 Into the soft mud along the shore of a river, pond or lake. 

 Nature, In order to preserve the life force contained In this 

 limb. Immediately sets to work to adapt this limb to Its new 

 surroundings. It can no longer depend on Its parent body 

 to carry It food and water from the soil and consequently, 

 through Its cell Intelligence, buds are formed on that portion 

 of the limb that Is burled In the mud that develop Into roots 

 performing the same functions that the roots of the parent 

 tree perform. The limb now Is nourished through the 

 agency of these newly formed roots and It develops Into a 

 tree through the process of adaptation. This Is an example 

 of speedy adaptation to meet a changed environment. Every 

 form of animal life must adapt Itself to changes In food, 

 climate, protection against enemies and other surroundings 

 In order to continue In the "struggle for existence." The 

 curly hair of the African negro furnished an example of 

 adaptation for the protection of the brain against the exces- 

 sive heat of the tropical regions of Africa. The excessive 

 heat In these regions will cause sun stroke to many white 

 persons even with their heads protected while the curly hair 

 of the negro forms air pockets that absorb the sun's heat
