ANALYSIS OP THE FOUR PRINCIPLES (CONTINUED). 



different influences through which it arises; while indiscriminate 

 survival and its equivalent, indiscriminate elimination, seem to be 

 sufficient for the designation of a process which, as compared with 

 selection, is rarely effective in producing the transformation of races. 



4. Table of the discriminate and indiscriminate forms oj the four segregative 



principles. 



THE EIGHT FORMS. 



THE RESULTS. 



PARTITION. 



1. Discriminate partition 

 ciation. 



segregate asso- 



2. Indiscriminate partition with more or less 



loss of power to perpetuate the original 

 habitudes unchanged. 



SUCCESS. 



3. Discriminate success -= election. 



4. Indiscriminate success indiscriminate 



failure. 



ISOLATION. 



5. Discriminate isolation segregate inter- 



generation. 



6. Indiscriminate isolation with more or less 



loss of power to reproduce the complete 

 average of the innate characters ot the orig- 

 inal stock. 



SURVIVAL. 



7. Discriminate survival selection. 



8. Indiscriminate survival indiscriminate 

 elimination. 



1 . Grouping of individuals according to habi- 



tudes and acquired characters, and so 

 producing habitudinal segregation, and 

 giving an initial tendency toward segre- 

 gate breeding. 



2. More or less divergence in the habitudes 



and acquired characters of the separated 

 groups, especially when the groups are 

 very small, and so producing initial habi- 

 tudinal segregation. 



3. Success and influence of individuals accord- 



ing to their acquired fitness for the condi- 

 tions, both social and physical, in which 

 they are placed, producing intensified 

 habitudinal segregation. 



4. When the number of individuals that es- 



cape from a sweeping catastrophe is very 

 small, they will be unable to perpetuate 

 the original social organization unchanged. 



5. Grouping of individuals according to their 



aptitudes and innate characters, and so 

 directly introducing segregate breeding 

 with divergence of characters, i. e., racial 

 segregation. 



6. More or less divergence in the aptitudes 



and innate characters of the isolated 

 groups, especially when at the time of the 

 first setting apart the group is represented 

 by but one, or but few, individuals, and 

 so producing initial racial segregation. 



7. The efficiency of individuals in living and 



propagating will vary (and so their survi- 

 val will vary) according to their innate 

 fitness for the struggle of life, and thus 

 the fitness of the race will be increased. 



8. When those indiscriminately surviving are 



very few, it will be impossible for them to 

 reproduce all the innate characters of the 

 original stock unchanged.
