The long-cherished traditions and myths which had gathered around the inquiry left little room for any other hypothesis than that the apparition of Man on the field of life was the last and crowning achievement of a long series of creative fiats which brought the present world-drama into existence.

But, notwithstanding the far-reaching significance of the evolution theory, the evolutionary stages of Man's career on the globe
