324 THE HISTORY OF CREATION, 
be accurately traced in detail on the basis of comparative 
philology. (Compare p. 331.) 
The total number of human individuals at present 
amounts to between 1,300 and 1,400 millions. In our 
Tabular Survey (p. 333) 1,350 millions has been assumed as 
the mean number. According to an approximate estimate, 
as far-as such a thing is possible, 1,200 millions of these are 
straight-haired men, only about 150 millions woolly-haired. 
The most highly developed species, Mongols and Mediterra- 
nese, far surpass all the other human species in numbers of 
individuals, for each of them alone comprises about 550 
millions. (Compare Friederich Miiller’s Ethnography, p. 30.) 
Of course the relative number of the twelve species fluc- 
tuates every year, and that too according to the law 
developed by Darwin, that in the struggle for life the more 
highly developed, the more favoured and larger groups 
of forms, possess the positive inclination and the certain 
tendency to spread more and more at the expense of 
the lower, more backward, and smaller groups. Thus the 
Mediterranean species, and within it the Indo-Germanic, 
have by means of the higher development of their brain 
surpassed all the other races and species in the struggle 
for life, and have already spread the net of their dominion 
over the whole globe. It is only the Mongolian species 
which can at all successfully, at least in certain respects, 
compete with the Mediterranean. Within the tropical 
regions, Negroes, Kaffres, and Nubians, as also the Malays 
and Dravidas, are in some measure protected against the 
encroachments of the Indo-Germanic tribes by their being 
better adapted for a hot climate; the case of the arctic 
tribes of the polar regions is similar. But the other races,
