MARXISM AND DARWINISM. U 



are ever more individuals born than can remain alire, 

 the struggle as to which shall remain alive must start 

 again and that creature that has some advantage 

 over the others will survive, but as these diverging 

 peculiarities are transmitted to the new generations, 

 nature itself does the choosing, and a new generation 

 will arise having changed peculiarities." 



Here we have another application for the origin 

 of the giraffe. When grass does not grow in some 

 places, the animals must nourish themselves on tree 

 leaves, and all those whose necks are too short to 

 reach these leaves must perish. In nature itself there 

 is selection, and nature selects only those having long 

 necks. In conformity with the selection done by the 

 animal breeder, Darwin called this process "natural 

 selection." 



This process must necessarily produce new spe- 

 cies. Because too many are born of a certain species, 

 more than the existing food supply can sustain, they 

 are forever trying to spread over a larger area. In 

 order to procure their food, those living in the woods 

 go to the plain, those living on the soil go into the 

 water, and those living on the ground climb on trees. 

 Under these new conditions divergence is necessary. 

 These divergencies are increased, and from the old 

 species a new one develops. This continuous move- 

 ment of existing species branching out into new rela- 

 tions results in these thousands of different animals 

 changing still more. 



While the Darwinian theory explains thus the 

 general descent of the animals, their transmutation 

 and formation out of primitive beings, it explains, 

 at the same time, the wonderful conformity through- 

 out nature. Formerly this wonderful conformity could
