The Evidence Furnished by Embryology 



in which we live and therefore they must be changed to use- 

 ful purposes or cast off In order to permit the more perfect 

 functioning of the useful parts. 



Many of the changes through which the human embryo 

 has passed before taking on Its human form represent char- 

 acters well known to men of science while others represent 

 characters not known to them but It Is known that they rep- 

 resent forms of departed types that belong in the chain of 

 animal life and that In the dim, dark past, they were the 

 highest forms of creation. Just as it Is Impossible for all of 

 us, or perhaps any of us, to trace the lineage of our ances- 

 try back fifty or even twenty-five generations ago and to 

 know the Influences that developed or retarded the bodies 

 and minds of our direct ancestors of that time, so It Is impos- 

 sible for us to know the life history of all the departed types 

 that have passed away leaving the gains of their lives as a 

 heritage to the succeeding types. But we do know that they 

 existed, that they played their part In the scheme of life, and 

 transmitted their useful experiences to their descendants just 

 as our direct human ancestors fifty generations ago have 

 transmitted to us the results of their labors which have been 

 reincarnated in us, their descendants. 



The mysterious forces of life can neither be explained 

 nor understood. The facts of Embryology cannot be chal- 

 lenged or disputed without abandoning the foundations of 

 reason. The early life history of all life Is reproduced in 

 a moving panorama in the embryonic development of all 

 mammals — step by step, stage by stage until the true mam- 

 mal form climbs one step higher than the preceding forms 

 have climbed. The urge of hunger and the compulsion to
