On the other hand the materials of which the body of the human embryo is built, are carried by the blood of the mother to their proper places in the body; and different portions of the same raw material, namely: the mother’s blood, are then differentiated and specialized into bones, muscles, nerves, arteries, veins, and other tissues, which go to make up the human body. These bones, muscles, nerves, etc., are all new creations, independent of those of the mother, father or any other human being that ever lived. Except the tiny germ-cell, which is less than one-trillionth part of the infant, at birth, they are built of atoms that never formed any part of any other human body. The human body is not only a compound physical structure, consisting of hundreds of bones, hundreds of muscles, arteries, veins, etc., and of trillions of cells; and of many organs, as the brain, heart, lungs, etc., but each of its tissues and each of its organs and parts has its own chemical composition and its own mechanical arrangement, peculiar to itself. For example, all the bones are composed of phosphate of lime, carbonate of lime and other elements peculiar to the bony tissue. Again, the atoms (cells) in each bone are mechanically arranged in a manner peculiar to that bone. Thus, the atoms in the bones of the skull are so arranged as to make them flat and curved, with an inner and outer plate; those in the other bones are so arranged as to make them long and cylindrical (arms and legs); others short (hands and feet); others flat and curved (ribs); others with complex forms (vertebræ), and so on. The muscular, vascular and nervous tissues are each composed of chemical elements peculiar to themselves; and their atoms are so arranged, mechanically, as to form the muscles, arteries, veins, nerves, etc. The human body is not only a compound physical structure, with all these tissues, organs, cells, etc., but life is added to all the other wonderful properties, which it possesses. Now, the chemical elements, which compose the bones, muscles, arteries, veins, nerves, etc., either assemble, automatically, and group themselves, chemically, and at the same time, automatically, arrange themselves, mechanically, in such a manner as to form the bones, muscles, arteries, veins, nerves, brain, heart, lungs, stomach, etc., without the aid of any extraneous psychic or creative force, or this wonderful work is done by the Creator, Himself. Which hypothesis is most plausible?
