Excerpt from Spirazines: A Type of Chemical Structure Bearing Upon the Constitution of Proteins and the Cause of LifeThat the phenomenon of self-duplication must be due, either wholly or partly, to Specific chem ical processes is generally admitted, but there is a prevailing opinion that the molecular structures which are necessary for this purpose must be ex tremely complex. The failure of all previous efforts to devise some type of molecular structure which is capable of duplicating itself does not prove, however, that the solution of the problem must lie in the direction of extreme complexity. The complex molecular structures which make up the tissues of the higher plants and animals have developed gradually in the course of evolution, and the fact that they are necessary for the proper physiological functioning of the particular organisms in which they now occur does not prove that they were also the original cause of the fun damental life processes in the more primitive organisms from which these higher plants and animals have developed.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
