16 CELL INTELLIGENCE THE CAUSE OF EVOLUTION 



builders? Are they intelligent beings? We must ask 

 the same questions in regard to the structures we see in 

 life. We see a tree. It is a stationary habitation of a 

 billion cells. We ask, who are the builders of that tree? 

 It is admitted now that the cells are the builders of the 

 trees they occupy. You ask, how can they build them? 

 They do so by gathering the material and arranging it 

 into the form of a tree. How could they do it? Because 

 they are intelligent beings. The reader may not be famil- 

 iar with Darwin's theory of evolution, so I shall briefly 

 state what it is : 



First. All animals vary. Hardly ever are two born 

 just alike. There is nearly always some point of differ- 

 ence. 



Second. All animals and plants multiply so rapidly 

 that all of them cannot possibly live. 



Third. All animals and plants are therefore in a con- 

 stant struggle with each other for food and existence. 



Fourth. Those who have by chance been born with 

 some feature that favors them in their struggle will live 

 and perpetuate their kind. 



Fifth. This favorable variation will be passed on to 

 the offspring through inheritance and in that way pre- 

 served to that species. 



Sixth. By this process of continual variation, struggle 

 for existence and inheritance, the different species of ani- 

 mals have arisen. Darwin has also added sexual selec- 

 tion. He shows that among many animals, there is a con- 

 test in the breeding season among the males for the pos- 

 session of the females. The contest is sometimes by 

 actual combat and sometimes by an attempt to attract the 

 favor of the female by the display of brilliant plumage or 

 by singing. Now evidently those males who have espe- 

 cially developed weapons for combat or especially beau-
