Synthesis by sunlight in relationship to the origin of life. Synthesis of formaldehyde from carbon dioxide and water by inorganic colloids acting as transformers of light energy

Abstract

At a discussion on the origin of life held by the joint sections of Zoology and Physiology of the British Association, at the Dundee Meeting, September, 1912, it was suggested by Moore that the first step towards the origin of life must have been the synthesis of organic matter from inorganic by the agency of inorganic colloids acting as transformers or catalysts for radiant solar energy. This suggestion was amplified and explained in a book written in November, 1912, by the same author. 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 pre-formed organic matter and must inevitably perish.
