TIME AND CHANGE 
time of Hadrian with the people of those countries 
to-day. 
We are prone to speak of man’s emergence from 
the lower orders as if it were a simple thing, almost 
like the going from one country into another. But 
try to think what it means; try to think of the slow 
transformation, of the long, toilsome road even 
from the halfway house of our simian ancestors. 
If we do not give him the benefit of the sudden 
mutation theory of the origin of species, then think 
of the slow process, hair by hair, as it were, by which 
a tailed, apelike arboreal animal was transformed 
into a hairless, tailless, erect, tool-using, fire-using, 
speech-forming anima]. We see in our own day in 
the case of the African negro, that centuries of our 
Northern climate have hardly any appreciable effect 
toward making a white man of him; nor, on the other 
hand, has exposure to the tropical sun had much 
more effect in making a negro of the white man. 
Probably it would take ten thousand years or more 
of these conditions to bleach the pigments out of the 
one skin and put them in the other. There is con- 
vincing proof from painting and figures found in 
Egypt that neither the African negro nor the 
Egyptian has changed in features in five thousand 
years. 
The most marvelous thing about man’s evolu- 
tion is the inborn upward impulse in some one low 
organism that rested not till it reached its goal in
