The object of this book is to set forth the principal data brought forward by naturalists bearing on the subject of the origin and development of the two lines of sexual demarcation, and by means of the facts observed by explorers among peoples in the various stages of development, to trace, so far as possible, the effect of such differentiation upon the individual, and upon the subsequent growth of human society.
