EVIDENCES OF EVOLUTION 
Of the many evidences of the kinship of all 
animals including man only a few can be men¬ 
tioned in this book. All animals, man included, 
are constructed on the same general plan. 
They have the same organs — brain, heart, 
lungs, digestive tract, nerves, skin—perform¬ 
ing the same functions for the same purposes. 
The skeleton of man can be compared, bone for 
bone, with that of a monkey, bat or seal. The 
bat’s membranous wing is ribbed with bones 
corresponding to the bones of a monkey’s or 
a man’s hand. The wing of both the bat and 
the bird has one bone from the shoulder to 
the first joint, and two bones from the first 
to the second joint, like the fore leg of quadru¬ 
peds and the arm of man—thus proving that 
the fore leg, the arm and the wing are only 
modifications of the same limb. The biped bird 
and biped man are modified quadrupeds. 
All the five hundred muscles of the human 
body correspond with the muscles of other 
mammals. Even the brain, wherein man dif¬ 
fers most from the lower animals, has the 
same chief fissures and folds in both man and 
the animal nearest man, the orang-outang. Man 
and the other animals have the same five 
senses and the same sense organs. They in 
common have the same basic emotions, such 
as surprise, jealousy, pride, hatred, shame, 
anger, grief, affection, and' a sense of the ludi¬ 
crous. Bucks says, “So is man’s so-called hu¬ 
man mind rooted in the senses and the in¬ 
stincts of all his ancetral species; and not only
