Höhere Organisation wird dadurch erreicht, daß Arbeitstheilung eintritt, indem 

 Functionen localisiert, Organe specialisiert werden. Die höchste Form ist die, 

 wo alle Functionen localisiert, alle Organe specialisiert sind. Von solchen Indi- 

 viduen zweigen sich andere ab, die sich einem Minimum von Lebensbedingungen 

 anzupassen streben und einen Theil ihrer Functionen entbehren. Da die mini- 

 malen Lebensbedingungen sehr verschiedenartig sind, können sehr verschieden 

 reducierte Individuenreihen entstehen.

»It seems, that we are driven to the conclusion, that the causes which have been 

 acting in producing changes . . must be changes which are able to act upon the 

 potential congenital quality of the individual, and that there is no reason for 

 associating the somewhat superficial and late responses . . of the parts of a grow- 

 ing individual to normal or abnormal forces of its environment with that more 

 subtle and profound disturbance, which is permanent and afi'ects the potential 

 character of the germ.«

Ofi'ers as a precise definition: »Whenever an organism reacts under an external 



force, that part of the reaction which is directly due to the force is an acquired 



character«. 

 Galton, Frc. , offers the following definition: »Characters are said to be acquired, 



when they are regularly found in those individuals only, who have been subjected 



to certain special and abnormal conditions«.
