PROOFS OF EVOLUTION.

certain forms of disease. In man as in some of 
the lower animals, a sort of pouch about two 
inches long, which is not only useless, but is a 
constant source of danger, is attached to the 
caecum of the large intestine. 
Another proof of man’s descent from an ape¬ 
like ancestor, is the fact that the human embryo, 
in common with such animals, has at one period 
of its growth, a free projecting tail, which shortens 
up before birth, leaving, however, several well- 
defined vertebrae at the end of the spine. These 
are wholly useless and are, moreover, subject to 
injury. 
The vascular system in man is also far from 
perfect, as we still retain, in part, such valvular 
arrangements as are best suited to the quadruped; 
and to the lack of a better arrangement many of 
life’s ills are due. Many of the visceral attach¬ 
ments in men, and especially in women, are also 
adapted to a creature which walks on “all fours,” 
but are very imperfect in their adaption to an 
upright posture of the body. If man was created 
out and out, such workmanship implies a woeful 
want of wisdom or constructive skill on the part 
of his maker. These facts, however, are readily 
explained on the theory of Evolution.
