COLLEGE ZOOLOGY 



FIG. 533. The gorilla, Gorilla gorilla. 

 (From Flower and Lydekker.) 



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 like 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 

 they belonged has been given the (^ropopitkecus) troglodytes, young. 



(From Flower and Lydekker, after 



name Pithecanthropus erectus. Wolf.)
