264 MAN --AN ADAPTIVE MECHANISM 



the action of the internal secretions of the ovaries or 

 testicles upon the kinetic system, by which is produced 

 the kinetic activity required to build up the organs 

 and to create the sex function. Therefore, wherever 

 there is a defect in a link of the kinetic system or 

 absence of efficiency in the ovaries or testicles, there 

 will be a correspondingly diminished expression of sex 

 phenomena. 



Such a conception of the development of the function 

 of reproduction might explain why wild animals, as a 

 rule, do not procreate in captivity. Food may be 

 abundant, shelter secure, the kinetic system active, 

 but the fear integration excludes the procreation stim- 

 ulus and prevents energy from being diverted into 

 normal procreative channels. Animals have been so 

 evolved that their tendency to breed is diminished in 

 the midst of hazardous or hostile environments. In 

 the past, such environments would have led to the 

 destruction of mother and offspring ; death would have 

 followed procreation in times of drouth and famine and 

 in a period of great cold with scarcity of food. This 

 phylogenetic fact may explain why at any time, when 

 the general nutrition is low, the poverty of the kinetic 

 system is such that energy cannot be spared for pro- 

 creation.

In addition to transforming energy for the adaptive 

 reactions of running, fighting, work, emotion, eliminat- 

 ing foreign proteins, combating infection and further- 

 ing growth and procreation, it may be suggested that
