CHAPTER XII. PROGRESS OF EVOLUTION IN CRUSTACEA. ACCORDING to all the characters established in the last paragraph, the Prawn that we traced from the Nauplius through states analogous to Zoëa and Mysis to the form of a Macrurous Crustacean appears at present to be the animal, which in the section of the higher Crustacea (Malacostraca) furnishes the truest and most complete indications of its primitive history. That it is the most complete is at once evident. That it is the truest must be

species deserve the greatest attention; but I am not at present quite convinced that there are such independent of the conditions to which they are subjected. I think you have done great service to the principle of evolution, which we both support, by publishing this work. I am the more glad to read it, as I had not time to read Wigand's great and tedious volume.

postscript is an understatement; in fact the author has entirely failed to understand the doctrine of Natural Selection as proposed by Darwin and Wallace. Thylacinus is the marsupial wolf of Australia and the resemblance to Canis, which is indeed striking, is by convergent evolution, and definitely not due to community of descent

But if the researches of geologists and the investigations of anatomists should ever demonstrate that he was derived from the lower animals in the same way that they have been derived from each other, we shall not be thereby debarred from believing, or from proving, that his intellectual capacities and his moral nature were not wholly developed by the same process. Neither natural selection nor the more general theory of evolution can give any account whatever of the origin of sensational or

An instrument has been developed in advance of the needs of its possessor. This subject is a vast one, and would require volumes for its proper elucidation, but enough, we think, has now been said, to indicate the possibility of a new stand-point for those who cannot accept the theory of evolution as expressing the whole truth in regard to the origin of man

that, on the theory of evolution and natural selection, a wide range of facts with regard to colour in nature have been co-ordinated and explained. Until at least an equally wide range of facts can be shown to be in harmony with any other theory, we can hardly be expected to abandon that which has already done such good service, and which has led us to the discovery of so many interesting and unexpected harmonies among the most common (but hitherto most neglected and least understood), of the

Natural Selection can Not do. In considering the question of the development of man by known natural laws, we must ever bear in mind the first principle of natural selection, no less than of the general theory of evolution, that all changes of form or structure, all increase in the size of an organ or in its complexity, all greater specialization or physiological division of labour, can only be brought about, in as much as it is for the good of the being so modified. Mr. Darwin himself has

possesses an organ quite disproportionate to his actual requirements an organ that seems prepared in advance, only to be fully utilized as he progresses in civilization. A brain slightly larger than that of the gorilla would, according to the evidence before us, fully have sufficed for the limited mental development of the savage; and we must therefore admit, that the large brain he actually possesses could never have been solely developed by any of those laws of evolution, whose essence is, that

The laws of evolution alone would, perhaps, never have produced a grain so well adapted to man's use as wheat and maize; such fruits as the seedless banana and bread-fruit; or such animals as the Guernsey milch cow, or the London dray-horse. Yet these so closely resemble the unaided productions of nature, that we may well imagine a being who had mastered the laws of development of organic forms through past ages, refusing to believe that any new power had been concerned in their

It is quite out of the question to suppose that the theory of Natural Selection does all this. Those, however, who have studied Mr. Spencer's work will be well aware that his theory of evolution may be applied to deal with the question in this its more extended light. And I believe that those who wish well for the survival of Natural Selection will do well to insist on its only

[13 November 1873] Charles Darwin Fiske's veneration for Darwin was hardly less than his veneration for Spencer. While he credited Spencer with being the first thinker of modern times to bring forward the idea of Evolution as the mode of manifestation of an unknown power underlying all the phenomena of the inorganic and organic universe, he recognized Darwin as having furnished the most indubitable proof of Evolution in the organic world by his epoch-making books, The Origin of Species and The
