CONTROLLED NATURAL SELECTION 

 AND VALUE MARKING 



CHAPTER I 



THE THEORY 



BEFORE statement of the Theory is given, 

 certain facts of Nature must be called atten- 

 tion to, upon which the Theory may be said 

 to rest. 



Firstly, the individuals of a species are, in 

 very many cases, not all of equal value. In 

 the vast majority of sexually differentiated 

 species, males are less valuable than females, 

 for these reasons : the soma carrying the 

 female germ cells, the female, does not dis- 

 charge its germ cells until they are fertilised, 

 and often partially developed into embryos. 

 Thus the female often is equivalent to male 

 and female, and when about to give birth to 

 young, to male and female in the form of 

 young, individuals of the next generation.
