One must remember that the most savage races known to us today are practically as far different from the highest American, European or Hindu types of Man as from the highest Apes. Indeed, it would seem far easier for a high Ape to evolve into a Kaffir, Hottentot, or Digger Indian, than for the latter to evolve into an Emerson, Shakespeare, or Hindu Sage. As Huxley has shown, the brain-structure of Man compared with that of the Chimpanzee shows differences but slight when compared with the difference between that of the Chimpanzee and that of the Lemur. The same authority informs us that in the important feature of the deeper brain furrows, and intricate convolutions, the chasm between the highest civilized man and the lowest savage is far greater than between the lowest savage and the highest man-like ape. Darwin, describing the Fuegians, who are among the very lowest forms of savages, says: "Their very signs and expressions are less intelligible to us than those of the domesticated animal. They are men who do not possess the instinct of those animals, nor yet appear to boast of human reason, or at least of arts consequent upon that reason." Professor Clodd, in describing the "primitive man," says: "Doubtless he was lower than the lowest of the savages of today--a powerful, cunning biped, with keen sense organs always sharper, in virtue of constant exercise, in the savage than in the civilized man (who supplements them by science), strong instincts, uncontrolled and fitful emotions, small faculty of wonder, and nascent reasoning power; unable to forecast tomorrow, or to comprehend yesterday, living from hand to mouth on the wild products of Nature, clothed in skin and bark, or daubed with clay, and finding shelter in trees and caves; ignorant of the simplest arts, save to chip a stone missile, and perhaps to produce fire; strong in his needs of life and vague sense of right to it and to what he could get, but slowly impelled by common perils and passions to form ties, loose and haphazard at the outset, with his kind, the power of combination with them depending on sounds, signs and gestures." Such was the ancestral man. Those who are interested in him are referred to the two wonderful tales of the cave-man written in the form of stories by two great modern novelists. The books referred to are (1) "_The Story of Ab_," by Stanley Waterloo, and (2) "_Before Adam_," by Jack London. They may be obtained from any bookseller. Both are works of fiction, with the scientific facts cleverly interwoven into them.
