These animals developed through most diverse forms to a certain level, and when the sun had just gone forth from the earth, the highest animal form was the fish, although not the fish of today. The form of the animals of that time was entirely different from that of the present fishes, but it stood at the same stage.

Others, however, retained a certain relation to the human shapes in the following way.
