A Story Outline of Evolution 



Ing on the skin, another the hair, another the bones, another 

 the muscles and so on until the entire structure with its cor- 

 related functions is completed and again ready to reproduce 

 its kind. Since the first or parent germ cell of the body first 

 divided, nothing new has come into the structure except food 

 and work. The forms of Nature have been changed but not 

 the substance. The grass of the fields has been changed Into 

 bone, muscle, blood, skin and brain by the life processes of 

 work and growth. Each organ has been developed for some 

 particular function necessary for the preservation of the 

 whole. 



The embryonic development of all mammals Is accom- 

 plished by much the same physical processes but human Em- 

 bryology has an Interesting appeal above all others because 

 It concerns the development of our own bodies. Just as we 

 have seen the development of writing, transportation, com- 

 munication, art, music and all other accomplishments in Cul- 

 tural Evolution from a crude beginning to a state of near 

 perfection, so likewise the development of the embryonic 

 cell, a thousand times more complex, may be traced with as 

 much certainty In Its various changes. It is not given to man 

 to see the mysterious life processes which cause these changes 

 but he can see the results of each change after the work h 

 done. 



The human embryo is moulded into shape and form like 

 a drop of rain forming from the vapors and then moulded 

 Into the many angled snow flake or ice crystal. It does not 

 begin as a human form, but instead. It begins with the form 

 of its remotest ancestor. It does not assume the human 

 form until It has repeated the forms through which its ances-
