This work is a solidification of some new matter with the substance of the ten Morse Lectures delivered at Union Theological Seminary in the spring of 1895.  Professor Tyler aims to trace the development of man from the simple living substance to his position at present, paying attention to incidental facts merely as incidental and contributory.  He keeps always in view the successive accomplishments of life as they appear in the person of accepted general truth, rather than in the guise of the facts of progress.

He begins by saying:  “We take for granted the probable truth of the theory of evolution as stated by Mr. Darwin, and that it applies to man as really as to any lower animal.”  He assumes that an acceptable historian of biology must possess a genealogical tree of the animal kingdom, and adds that a knowledge of the sequence of dominant functions or “physiological dynasties,” is quite as necessary to his inquiry as a history of the development of anatomical details.  Since the germs of the future are always concealed in the history of the present, he claims that “if we can trace this sequence of dominant functions, whose evolution has filled past ages, we can safely foretell something, at least, of man’s future development.”
