In the April–October 1826 edition of the quarterly "Edinburgh New Philosophical Journal" edited by Jameson, an anonymous paper praised "Mr. Lamarck, one of the most sagacious naturalists of our day" for having "expressed himself in the most unambiguous manner. He admits, on the one hand, the existence of the simplest infusory animals; on the other, the existence of the simplest worms, by means of spontaneous generation, that is, by an aggregation process of animal elements; and maintains, that all other animals, by the operation of external circumstances, are evolved from these in a double series, and in a gradual manner." – this was the first use of the word "evolved" in a modern sense, and was the first significant statement to relate Lamarckism to the geological record of living organisms of the past. Attribution has been disputed, the concepts point to Jameson as the author, combining the directional geological history of Earth proposed by Neptunism with progressive transformism (transmutation of species) shown by fossils. It is possible that the article was written by one of his students, Ami Boué or Robert Edmond Grant. Jameson's references to the Deluge in notes to his translation of Georges Cuvier's "Essay on the Theory of the Earth" had done much to foster Catastrophism, but his 1827 edition referred to a "succession of variations" caused by environmental conditions having "gradually conducted the classes of aquatic animals to their present state". and a later chapter described how "like the formation of rocks, we observe a regular succession of organic formations, the later always descending from the earlier, down to the present inhabitants of the earth, and to the last created being who was to exercise dominion over them", summarising elements of the ideas of Giambattista Brocchi.
