PROOFS FROM ARTIFICIAL BREEDING. 
It is well known that nearly all domestic 
animals, food-plants, fruits, and flowers have been 
greatly improved by man’s endeavor to produce 
higher and better forms. His success has been 
phenomenal in modifying size, form, color, speed, 
strength, and beauty. If such marvelous results 
may be achieved in one individual’s lifetime by 
accelerating the Law of Selection, what wonders 
might we not expect Nature to perform in the 
ages gone by ? 
The wild species have been modified by Natural 
Selection during countless ages. In a degree man 
can repeat and augment this developmental process 
in his own brief life; nay, he can almost witness 
an entire change of species. Individual inheritance 
is from all the preceding race, but strongest from 
the immediate parent. Heredity is cumulative, 
and tends toward fixity and stability, until finally 
the opposite tendency to reversion is overcome.
