172 EVOLUTION OF LIFE. 
Cows, cats, pigeons, chickens, give vent to their feelings "t 
sounds. Language, or the expression of one's thoughts, i 
therefore common i5 man and the lower animals. Let us 
see now what light is thrown on the origin of articulate 
า or the peculiar language of Man, by comparing its 
development in the child with the متا‎ of different 
races. It must be remembered that intelligent speech de- 
pends as much on the development of the brain as of the 
vocal organs, for Parrots and Ravens can talk. Naturally, 
then, words are wanting if there are no ideas to give rise to 
them. Hence the poorness of the languages of savage 
races, and the simple talk of the child. Further, one hears 
few verbs, prepositions, or conjunctions, in listening to the 
prattle of young children: their expressions are almost 
entirely composed of nouns and adjectives, —thus, “sugar 
good," *toy nice,"and soon. The language of savage nations 
is equally simple, often not rivaling even that of the children 
ofthe civilized. Hence lied philologists, like Grimm, 
Schleicher, Bleek, regard language as progressive, consid- 
ering the most ancient languages as much more simple than 
the modern ones. . They maintain that language is not an 
art, but a natural growth arising from the necessity felt by 
man of having some means of communicating his ideas. 
According to Schleicher, the most simply constructed lan- 
guages have been slowly developed out of the natural cries 
that Man has in common with animals. He considers th at, 
in the lapse of ages, languages experience great modifica- 
tions, some, indeed, altogether dying out, others becoming 
so changed that their origin cannot be certainly determined; 
that, comparatively speaking, language is a recently acquired 
faculty depending on development of brain and vocal organs; 
primitive Man having no language excepting the natural 
cries inherited from his Ape ancestors. Accepting this 
theory, we have an explanation of the fact that the roots in 
the languages of the lowest races of mankind resemble the
