five hundred pounds; walks on 

 the soles of its feet aided by 

 the backs of the hands; and is 

 ferocious and untamable. 



The chimpanzee, Pan (An- 

 thropopithecus) troglodytes (Fig. 

 534), also lives in West Africa. 

 It resembles the gorilla, but has 

 shorter arms and a smoother, 

 rounder skull. In many re- 

 spects the chimpanzee is more 

 nearly Jke man than any other 

 living mammal. It is easily 

 tamed. 



The family Hominid^e con- 

 tains the single living species, 



Homo sapiens, or man. Man differs from the other primates in 



the size of the brain, which is about twice as large as that of 



the highest monkey, and in his 



erect, bipedal locomotion. The 



hairy covering is not well de- 

 veloped, and the great toe is 



not opposable. The mental de- 

 velopment of man has enabled 



him to accommodate himself to 



every climate, and to dominate 



all other animals. Some fossil 



remains of a primate that were 



found in the upper Pliocene on 



the island of Java have been 



designated by Haeckel as " the 



last link " between the apes and 



man, and the animal to which Fig. 534- — The chimpanzee, Pan
