XIII of the Origin, Ed. i, Ch. XIV Ed. vi, begins with a similar statement. In the present Essay the author adds a note: The obviousness of the fact (i.e. the natural grouping of organisms) alone prevents it being remarkable. It is scarcely explicable by creationist: groups of aquatic, of vegetable feeders and carnivorous, etc., might resemble each other; but why as it is. So with plants - analogical resemblance thus accounted for. Must not here enter into details.’ This argument is incorporated with the text in the Origin, Ed. i.; Chapter VIII Unity of Type in the Great Classes; and Morphological Structures; Chapter IX Abortive or Rudimentary Organs; Chapter X Recapitulation and Conclusion;
