Iv. EARLY MAN 
A factor that has, no doubt, played an important 
part in man’s evolution is the much greater swing 
which the law of variation has in his case than in 
that of any other animal. The extent of variation 
in the mental capacity of men has no parallel in 
any other species in the animal kingdom. The 
individual differences between animals of the same 
species, in disposition, in intelligence, is consider- 
able, but in the case of man it is enormous. With 
this sweep of variation man’s development would 
be rapid. The most gifted led the race forward. 
Our civilization is the work of a few minds; all 
progress is the work of a few minds. The rank 
and file of mankind follow their natural captains 
and leaders. The law of variation has evidently 
worked more and more in man tlie farther he de- 
parted from the lower orders, so that he has pro- 
gressed with accelerated rapidity. Every advance 
gained made a greater advance possible. The pos- 
sibilities, say with dogs, are very limited; the possi- 
bilities with man are almost infinite. 
No doubt the first rude man, or the immediate 
animal ancestor of man, made himself a nest or a 
shelter from the storms long before he became a 
tool-user. The orang makes a platform of branches
