The study of the cosmos is a study of physical-chemical relationships.
Astronomy, which arose out of material developments, eventually gave rise to the next smaller great generalization of existence, geology, the science and study of the earth.
Some billions of years ago a hot gaseous mass emerged from the sun. In all the conflicting speculations and educated guesses as to the specific details of the origin of the earth, there is no quarrel that the solar system consists of the various planets revolving around the sun in their respective orbits.
It took a few billion years before the gaseous mass became a vast sea and, later, came the emergence of the geological formations. Evolution in geology can be traced through the strata by the fossils found in them. The evolutionary stages of geology may be summarized as archeozoic (transition to and beginnings of life), proterozoic (earliest life), paleozoic (ancient life), mesozoic (middle life, reptiles) and cenozoic (recent life, mammals).
In the course of a very long time there appeared on earth pre-biological forms which later developed into living matter. Organic life is only a more complex organization of inorganic substances which have acquired the properties of growth and reproduction. In order for life to arise on earth, propitious conditions had to exist. The earth’s average mean temperature had to cool sufficiently to support life, which can only exist within relatively very small limits of temperature. There also had to exist an atmosphere, moisture and other favourable circumstances. [2].
As a rule, charts of the tree of life start with the single-celled animal, as though this were the simplest and earliest form of life. Of course, this is not true. The single-celled animal is already a very complex form of a living being.
Inorganic matter, more especially carbon, with other elements, became joined together into complex molecules which were the building blocks of ultra-microscopic life. Of special significance is it that proteins are inorganic, yet under certain specific conditions function as organic matter. The viruses may be called the first true life forms. The next higher stage is bacteria. Eventually appeared the single-celled plants.
The primary distinction between plants and animals is that plants can subsist on inorganic matter, i.e., they can transform the inorganic into organic substances whereas animals can only subsist on the organic. In order of evolution, single-celled plants preceded single-celled animals.
Starting with the single-celled plant, the evolution of plants were algae, mosses, ferns, non-flowering seed producers and, its highest development, the flowering seed producers.
The evolution of animals was from single-celled animals into spores, fishes, reptiles, mammals and, finally, man. In this man’s eye view of the evolution of existence, we are only considering the main trunk and ignoring the branches of the tree.
Again, we see that evolution is a continuing process. The appearance of homo sapiens on the scene gave rise to sociology. In a very real sense, sociology is but a division of biology; which, in turn, is a division of geology; in its turn, a division of astronomy; which is but a branch of the greatest generalization of all matter.
Man "is the only animal species that, from the very moment he came into existence, has been continuously changing and during a continuing process has become a different thing.” [3] Through the interrelations of his brain and thinking processes, his acquirements of speech and the development of tools man has become a social animal whose evolution can be traced through his social organizations. Only a Marxist, such as Anton Pannekoek in his invaluable “Anthropogenesis,” [3] could have filled in the gap between the primates and the origin of homo sapiens, i.e., tied Darwinism and Marxism into an interrelated whole.
Man, the social animal, evolved from the pre-cave man into primitive tribal society (savagery and barbarism) and, then, into chattel slavery, through feudalism into capitalism and is now on the very dawn of a new society.
This whole development of social evolution arose from changes taking place in the material conditions of existence under which mankind lived. In response to these changes, there evolved changes in his ideas and institutions. Man makes his own history, “not out of the whole cloth” but out of the conditions at hand. This is Marxism, in a nutshell.
Our tribute to Darwin is for emancipating man from biological superstitions by his revolutionary contribution revealing the material forces that brought about the evolution of the species in biology.
Our tribute to Marx is for furnishing the key that unlocked the mystery of mankind’s social evolution and for establishing the understanding that it is now possible and necessary for man to be master of his own form of social organization and, at the same time, the lord over nature.

(concluded)
[2] All the speculations about life on other planets in the cosmos, more especially our sister planets in the solar system—Mars and Venus, are predicated upon the existence on them of the conditions favourable for the support of life. Though there may be millions of planets in the cosmos (a relatively small number, actually), it is not reasonable to imagine that very many of them have life-forms.
