PROOFS OF EVOLUTION.

in the individual. At a certain point, the embryo 
ceases to personate its ancestors, and commences 
to take on the form peculiar to its own kind. 
Professor Haeckel, in his “ Evolution of Man,” 
has given a series of plates showing the develop¬ 
ment of the embryos of the fish, salamander, 
tortoise, chick, hog, calf, rabbit, and man. At 
certain stages in their pre-natal development, 
there is an exact resemblance of form among them 
all, each becoming specialized as it approaches the 
time of birth. At one period of its growth the 
human embryo has the long, free, swinging tail of 
the races below it. 
Whither does all this array of facts lead ? 
What explanation can the creationist give? If 
man was fashioned at once, why drag him to 
nativity through all the forms of the brute- 
creation ? Why masquerade him in the guise of 
the dumb, ferocious, and soul-less brutes ? There 
is no reasonable explanation of these facts outside 
of the theory of development. There is no escape 
from the conclusion that man, and all mammals, 
have a common origin and a similar philogenic 
history. How strange and stirring is the thought. 
The changes of ages are compressed into the brief 
span of embryonic life !
