Ascent Of Man

In these pages an attempt is made to tell in a plain way a few of the things which science is now seeing with regard to the ascent of man. What science has to say about himself is of transcendent interest to man, and the practical bearings of this theme are coming to be more vital than any on the field of knowledge. The thread which binds the facts is, it is true, but a hypothesis. As the theory, nevertheless, with which at present all scientific work is being done, it is assumed in every page found in this book.
