According to the testimony of those who have made a study of the various abnormalities in the human organism, the ears of men present a greater range of variations than do those of women, and the cases in which supernumerary digits appear in males are as two to one, compared with females presenting the same structural defect. Of one hundred and fifty-two cases of this kind tabulated by Burt Wilder, eighty-six were males and thirty-nine females, the sex of the remaining twenty-seven being unknown. Mr. Darwin wishes us to remember, however, that “women would more frequently endeavour to conceal a deformity of this kind than men.” Although it is quite natural for women to abhor abnormalities and deformities, it is to be doubted if they would succeed for any considerable length of time in concealing the deformity of an organ which, like the hand, is usually uncovered, and which in waking hours, is in almost constant use. One of the principal characters which distinguishes the human animal from the lower orders is the absence of a natural covering for the skin. That mankind have descended from hair-covered progenitors is the inevitable conclusion of all those who accept the theory of the evolution of species, the straggling hairs which are scattered over the body of man being the rudiments of a uniform hairy coat which enveloped his ancestors. We are informed that a hairy covering for the body, pointed ears which were capable of movement, and a tail provided with the proper muscles, were among the undoubted characters of the antecedents of the human race. In addition to these, among the males, were developed great canine teeth which were used as weapons against their rivals. As the lack of a hairy coat for the body constitutes one of the principal characteristics which distinguishes man from the lower animals, it would seem that a knowledge of the order of time in which the two sexes became divested of their natural covering would serve as a hint to indicate their relative stages of development. In a paper read some years ago at a meeting of the Anthropological Institute in London, Miss Bird (Mrs. Bishop) the well-known traveller, gave a description of the Ainos, a race of people found chiefly in the island of Yezo, and who, it is thought probable, were the original inhabitants of Japan. The peculiarity of this people is, that the men are covered with a thick coat of black hair. The women, we are told, “are not hairy like the men,” but “have soft brown skins.” Upon this subject of hairiness, Mr. Darwin says: As the body of woman is less hairy than that of man, and as this character is common to all races, we may conclude that it was our female semi-human ancestors who were first divested of hair, and that this occurred at an extremely remote period before the several races had diverged from a common stock.
