It prefers the life in the trees, however, in which it builds nests serving for rest and concealment. The go- rilla (Fig. 140), the largest of apes, attain- ing a height of over five feet and a weight of two hundred pounds, is a native of Africa, where it lives in families and sub- sists on fruits. The same region is the home of the chimpan- zee, which in its vari- ous characteristics ap- proaches most nearly to man. Man {Homo sajri- ens) is distinguished by the inability to oppose the big toe as he does his thumb— a feature associated with his erect position—and by the rela- tively enormous size of the brain. Even in an average four- year-old child or an Australian bushman the brain is twice as large as in the gorilla. With this relatively great develop- ment of the nervous system is correlated superior mental faculties, which together with social habits and powers of speech exalt man to a position far above the highest Fig. 141.—Gorilla (Gorilla)..
