Then another faculty added its powers to the sense of sight and feeling, for the atmosphere in which the reptilian tribes were living half the time or more were sending out sound waves which touched the nervous filaments of the central battery of the brain, and as the eye had formed to respond to the waves of ether caused by the electric currents of the sun, so a new organ began its formation in response to the incoming waves of power the atmosphere brought to the brain-cells, and the ear began to gather in concentric circles around the brain-center, and a new sense--that of hearing--was formed. Thus there was an additional increase of the power of perception or instinct. Thus were evolved all types of animal form and animal instinct. They were the result of electric energy, sense perception, and long ages of growth, comparison and environment. Then came man, the highest type of animal organism. Man may have passed the successive changes and transmutations of form that the shifting vibratory rates of the planet responded to in the long period of world building. He may have attained to the grade of animal activity as a mind of the highest order in bodily form before he received the spiritual powers and intellectual force which he has exhibited all along the ages, after all animal forms had battled with the elements in the struggles to keep in equilibrium between the surging tides of electrical dispersion and magnetic concentration. Certain it is man holds his own by virtue of his steady rise in mental power which has no limit of evolution in the present stage of physical life and psychic life. And there are no known boundaries of his power to penetrate all mysteries and explore all conditions of existence "wherever being has laid foundations, or law is working out the problems of infinite destiny." Man came as a spiritual creation. Many scientists discard the religious or Mosaic concept of a special creation of man and a divine revelation, and hold that the revelations of science are the only revelations of God that the world can regard as reliable.
