So you see that the amoeba has taken a step upward from the moneron, and is beginning to appreciate the convenience of parts and organs.
From the moneron he proceeds to the amoeba a simple cell, with a kernel, which still corresponds to the egg of man in its first state. To the fourth stage he assigns the planæa, corresponding to the embryonic development of an albumen and the planula or ciliated larva.
Let us begin with the Protozoa, or one-celled forms the lowest form of animal life. The lowest form of this lowest class is that remarkable creature that we have mentioned in previous lessons the Moneron. This creature lives in water, the natural element in which organic life is believed to have had its beginning.
The short, blunt, finger-like processes that are thrust out at the surface of the creeping Protamoeba serve for getting food as well as for locomotion. A The whole moneron, moving like an ordinary amoeba by thrusting out changeable processes. B It divides into two halves by a constriction in the middle. C The two halves separate, and each becomes an independent individual.
We must not assume the spontaneous generation of even the simplest cell, for this itself consists of at least two parts the internal, firm nuclear substance, and the external, softer cellular substance or the protoplasm of the cell-body. These two parts must have been formed by differentiation from the indifferent plasson of a moneron, or a cytode.
We see things that we call "forms of life," varying in manifestation from the tiny speck of slime that we call the Moneron, up to that form that we call Man. But study this world of manifestations by means of science and research and such study is of greatest value still we must find ourselves brought to a point where we cannot progress further.
So the vertebrate must forever remain a vertebrate, and the articulate forever an articulate. Were they both evolved from the same unit? We are anxious to know, how from a pulpy mass of flesh, from a moneron, a creature of one substance, vertebrates were evolved.
All of these three classes of functions the Moneron performs but with any part of its body, or with all of it. Every part, or the whole, of the Moneron absorbs food and oxygen it is all mouth and lungs. Every part, or the whole, digests the food it is all stomach. Every part, or the whole, performs the reproductive function it is all reproductive organism.
At that depth dere is absolute darkness, but we know that creatures live down dere, und fight, und eat, und die. "'But what of it? Why can't we see that thing? "'Because, in der ages that haf passed in its evolution from der original moneron, it has never been exposed to light I mean visible light, der light that contains der seven colors of der spectrum.
And it is impossible to think of "purposive tendency" without assuming the existence of mental power of some kind. And where can such a power be located if not in the form itself? When we consider that the Will is acting in and through all forms of Life, from highest to lowest from Moneron to Man we can at once recognize the source of the power and activity.
