Excerpt from book: CHAPTER III SYNTHESIS BY SUNLIGHT IN RELATIONSHIP TO THE ORIGIN OP LIFE SYNTHESIS OF FORMALDEHYDE FROM CARBON DIOXIDE AND WATER BY INORGANIC COLLOIDS ACTING AS TRANSFORMERS OF LIGHT ENERGY. It is important to emphasise the point that in considering the origin of life in a world containing inorganic matter only, the nutrition of the first living structure on such a world must be carefully borne in mind. This observation is still true whether life is to be regarded as arising de novo on the planet, or as being borne there from some other planet as a germ from pre-existent life. No living organism such as a bacterium or mould which did not possess the power of transforming energy and of synthesising organic from inorganic matter could exist or flourish in total absence of preformed organic matter and must inevitably perish. A substance acting as a transformer of light energy with accompanying synthesis of organic from inorganic matter now exists in our world, in chlorophyll, the green colouring matter of plants, and also allied bodies such as the blue-green colouring matter of the Cyanophyceae1 possess a similar power. But both these substances are exceedingly highly organised and complex, quite unsuitable by their nature to be thought of as the first stage in the evolution of organic from inorganic matter at the dawning of life in a world hitherto devoid of anything organic. The protoplasm of the living cell also is built up of the most complex organic compounds known to us such as could scarcely arise in an entirely inorganic world as the first step from inorganic to organic matter. The first primeval step would appear to be indicated by the union of single crystalloidal inorganic molecules to form inorganic colloids, and that these meta-stable colloids acting o...
