Darwin included evidence that he had gathered on <A href="/wiki/Second_voyage_of_HMS_Beagle" title="Second voyage of HMS Beagle">the <I>Beagle</I> expedition</A> in the 1830s and his subsequent findings from research, correspondence, and experimentation.<SUP id="cite_ref-5" class="reference"><A href="#cite_note-5">[5]</A></SUP></P>
<P><A href="/wiki/History_of_evolutionary_thought" title="History of evolutionary thought">Various evolutionary ideas</A> had already been proposed to explain <A href="/wiki/History_of_biology" title="History of biology">new findings in biology</A>. There was growing support for such ideas among dissident anatomists and the general public, but during the first half of the 19th century the English scientific establishment was closely tied to the <A href="/wiki/Church_of_England" title="Church of England">Church of England</A>, while science was part of <A href="/wiki/Natural_theology" title="Natural theology">natural theology</A>. Ideas about the <A href="/wiki/Transmutation_of_species" title="Transmutation of species">transmutation of species</A> were controversial as they conflicted with the beliefs that species were unchanging parts of a designed hierarchy and that humans were unique, unrelated to other animals. The political and theological implications were intensely debated, but transmutation was not accepted by the scientific mainstream.</P>
<P>The book was written for non-specialist readers and attracted widespread interest upon its publication. As Darwin was an eminent scientist, his findings were taken seriously and the evidence he presented generated scientific, philosophical, and religious discussion. The debate over the book contributed to the campaign by <A href="/wiki/Thomas_Henry_Huxley" title="Thomas Henry Huxley">T. H. Huxley</A> and his fellow members of the <A href="/wiki/X_Club" title="X Club">X Club</A> to <A href="/wiki/Secularity" title="Secularity">secularise</A> science by promoting <A href="/wiki/Naturalism_(philosophy)" title="Naturalism (philosophy)">scientific naturalism</A>. Within two decades there was widespread scientific agreement that evolution, with a branching pattern of common descent, had occurred, but scientists were slow to give natural selection the significance that Darwin thought appropriate. During "<A href="/wiki/The_eclipse_of_Darwinism" title="The eclipse of Darwinism">the eclipse of Darwinism</A>" from the 1880s to the 1930s, various other mechanisms of evolution were given more credit. With the development of the <A href="/wiki/Extended_evolutionary_synthesis" title="Extended evolutionary synthesis">modern evolutionary synthesis</A> in the 1930s and 1940s, Darwin's concept of evolutionary <A href="/wiki/Adaptation" title="Adaptation">adaptation</A> through natural selection became central to modern evolutionary theory, and it has now become the unifying concept of the <A href="/wiki/Life_science" class="mw-redirect" title="Life science">life sciences</A>.</P>

<P>In November 1844, the anonymously published <A href="/wiki/Popular_science" title="Popular science">popular science</A> book <I><A href="/wiki/Vestiges_of_the_Natural_History_of_Creation" title="Vestiges of the Natural History of Creation">Vestiges of the Natural History of Creation</A></I>, written by Scottish journalist <A href="/wiki/Robert_Chambers_(journalist)" class="mw-redirect" title="Robert Chambers (journalist)">Robert Chambers</A>, widened public interest in the concept of transmutation of species. <I>Vestiges</I> used evidence from the fossil record and embryology to support the claim that living things had progressed from the simple to the more complex over time. But it proposed a linear progression rather than the branching common descent theory behind Darwin's work in progress, and it ignored <A href="/wiki/Adaptation" title="Adaptation">adaptation</A>. Darwin read it soon after publication, and scorned its amateurish geology and zoology,<SUP id="cite_ref-41" class="reference"><A href="#cite_note-41">[41]</A></SUP> but he carefully reviewed his own arguments after leading scientists, including Adam Sedgwick, attacked its morality and scientific errors.<SUP id="cite_ref-42" class="reference"><A href="#cite_note-42">[42]</A></SUP> <I>Vestiges</I> had significant influence on public opinion, and the intense debate helped to pave the way for the acceptance of the more scientifically sophisticated <I>Origin</I> by moving evolutionary speculation into the mainstream. While few naturalists were willing to consider transmutation, <A href="/wiki/Herbert_Spencer" title="Herbert Spencer">Herbert Spencer</A> became an active proponent of Lamarckism and progressive development in the 1850s.<SUP id="cite_ref-43" class="reference"><A href="#cite_note-43">[43]</A></SUP></P>
<P>Hooker was persuaded to take away a copy of the "Essay" in January 1847, and eventually sent a page of notes giving Darwin much needed feedback. Reminded of his lack of expertise in <A href="/wiki/Taxonomy_(biology)" title="Taxonomy (biology)">taxonomy</A>, Darwin began an eight-year study of <A href="/wiki/Barnacle" title="Barnacle">barnacles</A>, becoming the leading expert on their classification. Using his theory, he discovered <A href="/wiki/Homology_(biology)" title="Homology (biology)">homologies</A> showing that slightly changed body parts served different functions to meet new conditions, and he found an <A href="/wiki/Androdioecy" title="Androdioecy">intermediate stage</A> in the evolution of <A href="/wiki/Gonochorism" title="Gonochorism">distinct sexes</A>.<SUP id="cite_ref-bowl169_44-0" class="reference"><A href="#cite_note-bowl169-44">[44]</A></SUP><SUP id="cite_ref-45" class="reference"><A href="#cite_note-45">[45]</A></SUP></P>
<P>Darwin's barnacle studies convinced him that variation arose constantly and not just in response to changed circumstances. In 1854, he completed the last part of his <I>Beagle</I>-related writing and began working full-time on evolution. He now realised that the branching pattern of <A href="/wiki/Genetic_divergence" title="Genetic divergence">evolutionary divergence</A> was explained by natural selection working constantly to improve adaptation. His thinking changed from the view that <A href="/wiki/Allopatric_speciation" title="Allopatric speciation">species formed in isolated populations only</A>, as on islands, to an emphasis on <A href="/wiki/Sympatric_speciation" title="Sympatric speciation">speciation without isolation</A>; that is, he saw increasing specialisation within large stable populations as continuously exploiting new <A href="/wiki/Ecological_niche" title="Ecological niche">ecological niches</A>. He conducted empirical research focusing on difficulties with his theory. He studied the developmental and anatomical differences between different breeds of many domestic animals, became actively involved in <A href="/wiki/Fancy_pigeon" title="Fancy pigeon">fancy pigeon</A> breeding, and experimented (with the help of his son <A href="/wiki/Francis_Darwin" title="Francis Darwin">Francis</A>) on ways that plant seeds and animals might disperse across oceans to colonise distant islands.

Reasons suggested have included fear of religious persecution or social disgrace if his views were revealed, and concern about upsetting his clergymen naturalist friends or his pious wife Emma. <A href="/wiki/Charles_Darwin%27s_illness" class="mw-redirect" title="Charles Darwin's illness">Charles Darwin's illness</A> caused repeated delays. His paper on <A href="/wiki/Glen_Roy" title="Glen Roy">Glen Roy</A> had proved embarrassingly wrong, and he may have wanted to be sure he was correct. <A href="/wiki/David_Quammen" title="David Quammen">David Quammen</A> has suggested all these factors may have contributed, and notes Darwin's large output of books and busy family life during that time.<SUP id="cite_ref-50" class="reference"><A href="#cite_note-50">[50]</A></SUP></P>
<P>A more recent study by science historian <A href="/wiki/John_van_Wyhe" title="John van Wyhe">John van Wyhe</A> has determined that the idea that Darwin delayed publication only dates back to the 1940s, and Darwin's contemporaries thought the time he took was reasonable. Darwin always finished one book before starting another. While he was researching, he told many people about his interest in transmutation without causing outrage. He firmly intended to publish, but it was not until September 1854 that he could work on it full-time. His 1846 estimate that writing his "big book" would take five years proved optimistic.<SUP id="cite_ref-vW_time_to_publish_48-1" class="reference"><A href="#cite_note-vW_time_to_publish-48">[48]</A></SUP></P>

<P>An 1855 paper on the "introduction" of species, written by <A href="/wiki/Alfred_Russel_Wallace" title="Alfred Russel Wallace">Alfred Russel Wallace</A>, claimed that patterns in the geographical distribution of living and fossil species could be explained if every new species always came into existence near an already existing, closely related species.<SUP id="cite_ref-51" class="reference"><A href="#cite_note-51">[51]</A></SUP> <A href="/wiki/Charles_Lyell" title="Charles Lyell">Charles Lyell</A> recognised the implications of Wallace's paper and its possible connection to Darwin's work, although Darwin did not, and in a letter written on 1–2 May 1856 Lyell urged Darwin to publish his theory to establish priority. Darwin was torn between the desire to set out a full and convincing account and the pressure to quickly produce a short paper. He met Lyell, and in correspondence with <A href="/wiki/Joseph_Dalton_Hooker" title="Joseph Dalton Hooker">Joseph Dalton Hooker</A> affirmed that he did not want to expose his ideas to review by an editor as would have been required to publish in an academic journal. He began a "sketch" account on 14 May 1856, and by July had decided to produce a full technical treatise on species as his "big book" on <I><A href="/wiki/Natural_Selection_(manuscript)" title="Natural Selection (manuscript)">Natural Selection</A></I>.

<P>Darwin was hard at work on the manuscript for his "big book" on <I><A href="/wiki/Natural_Selection_(manuscript)" title="Natural Selection (manuscript)">Natural Selection</A></I>, when on 18 June 1858 he received a parcel from Wallace, who stayed on the <A href="/wiki/Maluku_Islands" title="Maluku Islands">Maluku Islands</A> (<A href="/wiki/Ternate" title="Ternate">Ternate</A> and Gilolo).

<P>By mid March 1859 Darwin's abstract had reached the stage where he was thinking of early publication; Lyell suggested the publisher <A href="/wiki/John_Murray_(publisher)" title="John Murray (publisher)">John Murray</A>, and met with him to find if he would be willing to publish. On 28 March Darwin wrote to Lyell asking about progress, and offering to give Murray assurances "that my Book is not more <I>un</I>-orthodox, than the subject makes inevitable."

<P>Murray's response was favourable, and a very pleased Darwin told Lyell on 30 March that he would "send shortly a large bundle of M.S. but unfortunately I cannot for a week, as the three first chapters are in three copyists’ hands". He bowed to Murray's objection to "abstract" in the title, though he felt it excused the lack of references, but wanted to keep "natural selection" which was "constantly used in all works on Breeding", and hoped "to retain it with Explanation, somewhat as thus",— <I>Through Natural Selection or the preservation of favoured races</I>.<SUP id="cite_ref-FOOTNOTEDesmondMoore2009306_65-1" class="reference"><A href="#cite_note-FOOTNOTEDesmondMoore2009306-65">[65]</A></SUP><SUP id="cite_ref-Letter_2439_66-0" class="reference"><A href="#cite_note-Letter_2439-66">[66]</A></SUP> On 31 March Darwin wrote to Murray in confirmation, and listed headings of the 12 chapters in progress: he had drafted all except "XII.

American botanist Asa Gray (1810–1888)</DIV>
</DIV>
</DIV>
<P>In the United States, botanist <A href="/wiki/Asa_Gray" title="Asa Gray">Asa Gray</A>, an American colleague of Darwin, negotiated with a Boston publisher for publication of an authorised American version, but learnt that two New York publishing firms were already planning to exploit the absence of international <A href="/wiki/Copyright" title="Copyright">copyright</A> to print <I>Origin</I>.<SUP id="cite_ref-Letter2592_91-0" class="reference"><A href="#cite_note-Letter2592-91">[91]</A></SUP> Darwin was delighted by the popularity of the book, and asked Gray to keep any profits.<SUP id="cite_ref-Letter2665_92-0" class="reference"><A href="#cite_note-Letter2665-92">[92]</A></SUP> Gray managed to negotiate a 5% royalty with <A href="/wiki/D._Appleton_%26_Company" title="D.

In a May letter, Darwin mentioned a print run of 2,500 copies, but it is not clear if this referred to the first printing only as there were four that year.<SUP id="cite_ref-Freeman_1977_2-3" class="reference"><A href="#cite_note-Freeman_1977-2">[2]</A></SUP><SUP id="cite_ref-94" class="reference"><A href="#cite_note-94">[94]</A></SUP></P>

<P>Chapter VI begins by saying the next three chapters will address possible objections to the theory, the first being that often no intermediate forms between closely related species are found, though the theory implies such forms must have existed. As Darwin noted, "Firstly, why, if species have descended from other species by insensibly fine gradations, do we not everywhere see innumerable transitional forms? Why is not all nature in confusion, instead of the species being, as we see them, well defined?"<SUP id="cite_ref-137" class="reference"><A href="#cite_note-137">[137]</A></SUP> Darwin attributed this to the competition between different forms, combined with the small number of individuals of intermediate forms, often leading to extinction of such forms.<SUP id="cite_ref-138" class="reference"><A href="#cite_note-138">[138]</A></SUP> This difficulty can be referred to as the absence or rarity of transitional varieties in habitat space.</P>
<P>Another difficulty, related to the first one, is the absence or rarity of transitional varieties in time. Darwin commented that by the theory of natural selection "innumerable transitional forms must have existed," and wondered "why do we not find them embedded in countless numbers in the crust of the earth?" <SUP id="cite_ref-139" class="reference"><A href="#cite_note-139">[139]</A></SUP> (for further discussion of these difficulties, see <A href="/wiki/Speciation#Darwin's_dilemma:_Why_do_species_exist?" title="Speciation">Speciation#Darwin's dilemma: Why do species exist?</A> and Bernstein et al.<SUP id="cite_ref-140" class="reference"><A href="#cite_note-140">[140]</A></SUP> and Michod<SUP id="cite_ref-141" class="reference"><A href="#cite_note-141">[141]</A></SUP>)</P>
<P>The chapter then deals with whether natural selection could produce complex specialised structures, and the behaviours to use them, when it would be difficult to imagine how intermediate forms could be functional. Darwin said:</P>
<BLOCKQUOTE>
<P>Secondly, is it possible that an animal having, for instance, the structure and habits of a bat, could have been formed by the modification of some animal with wholly different habits? Can we believe that natural selection could produce, on the one hand, organs of trifling importance, such as the tail of a giraffe, which serves as a fly-flapper, and, on the other hand, organs of such wonderful structure, as the eye, of which we hardly as yet fully understand the inimitable perfection?<SUP id="cite_ref-142" class="reference"><A href="#cite_note-142">[142]</A></SUP></P>
</BLOCKQUOTE>
<P>His answer was that in many cases animals exist with intermediate structures that are functional. He presented <A href="/wiki/Flying_squirrels" class="mw-redirect" title="Flying squirrels">flying squirrels</A>, and <A href="/wiki/Flying_lemurs" class="mw-redirect" title="Flying lemurs">flying lemurs</A> as examples of how bats might have evolved from non-flying ancestors.<SUP id="cite_ref-143" class="reference"><A href="#cite_note-143">[143]</A></SUP> He discussed various simple eyes found in invertebrates, starting with nothing more than an optic nerve coated with pigment, as examples of how the <A href="/wiki/Evolution_of_the_eye" title="Evolution of the eye">vertebrate eye could have evolved</A>. Darwin concludes: "If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.

<P>Chapter VII (of the first edition) addresses the evolution of instincts. His examples included two he had investigated experimentally: <A href="/wiki/Slave-making_ant" title="Slave-making ant">slave-making ants</A> and the construction of hexagonal cells by honey bees. Darwin noted that some species of slave-making ants were more dependent on slaves than others, and he observed that many ant species will collect and store the pupae of other species as food. He thought it reasonable that species with an extreme dependency on slave workers had evolved in incremental steps. He suggested that bees that make hexagonal cells evolved in steps from bees that made round cells, under pressure from natural selection to economise wax. Darwin concluded:</P>
<BLOCKQUOTE>
<P>Finally, it may not be a logical deduction, but to my imagination it is far more satisfactory to look at such instincts as the young cuckoo ejecting its foster-brothers, —ants making slaves, —the larvæ of ichneumonidæ feeding within the live bodies of caterpillars, —not as specially endowed or created instincts, but as small consequences of one general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.<SUP id="cite_ref-149" class="reference"><A href="#cite_note-149">[149]</A></SUP></P>

<P>Chapter VIII addresses the idea that species had special characteristics that prevented hybrids from being fertile in order to preserve separately created species. Darwin said that, far from being constant, the difficulty in producing hybrids of related species, and the viability and fertility of the hybrids, varied greatly, especially among plants. Sometimes what were widely considered to be separate species produced fertile hybrid offspring freely, and in other cases what were considered to be mere varieties of the same species could only be crossed with difficulty. Darwin concluded: "Finally, then, the facts briefly given in this chapter do not seem to me opposed to, but even rather to support the view, that there is no fundamental distinction between species and varieties."<SUP id="cite_ref-150" class="reference"><A href="#cite_note-150">[150]</A></SUP></P>
<P>In the sixth edition Darwin inserted a new chapter VII (renumbering the subsequent chapters) to respond to criticisms of earlier editions, including the objection that many features of organisms were not adaptive and could not have been produced by natural selection. He said some such features could have been by-products of adaptive changes to other features, and that often features seemed non-adaptive because their function was unknown, as shown by his book on <I><A href="/wiki/Fertilisation_of_Orchids" title="Fertilisation of Orchids">Fertilisation of Orchids</A></I> that explained how their elaborate structures facilitated pollination by insects. Much of the chapter responds to <A href="/wiki/George_Jackson_Mivart" class="mw-redirect" title="George Jackson Mivart">George Jackson Mivart</A>'s criticisms, including his claim that features such as <A href="/wiki/Baleen" title="Baleen">baleen</A> filters in whales, <A href="/wiki/Flatfish" title="Flatfish">flatfish</A> with both eyes on one side and the camouflage of <A href="/wiki/Phasmatodea" title="Phasmatodea">stick insects</A> could not have evolved through natural selection because intermediate stages would not have been adaptive.

Evolved local varieties which migrated into a wider area would seem to be the sudden appearance of a new species.

<P>Chapter XI deals with evidence from <A href="/wiki/Biogeography" title="Biogeography">biogeography</A>, starting with the observation that differences in flora and fauna from separate regions cannot be explained by environmental differences alone; South America, Africa, and Australia all have regions with similar climates at similar latitudes, but those regions have very different plants and animals. The species found in one area of a continent are more closely allied with species found in other regions of that same continent than to species found on other continents. Darwin noted that barriers to migration played an important role in the differences between the species of different regions. The coastal sea life of the Atlantic and Pacific sides of Central America had almost no species in common even though the <A href="/wiki/Isthmus_of_Panama" title="Isthmus of Panama">Isthmus of Panama</A> was only a few miles wide. His explanation was a combination of migration and descent with modification. He went on to say: "On this principle of inheritance with modification, we can understand how it is that sections of genera, whole genera, and even families are confined to the same areas, as is so commonly and notoriously the case."<SUP id="cite_ref-160" class="reference"><A href="#cite_note-160">[160]</A></SUP> Darwin explained how a volcanic island formed a few hundred miles from a continent might be colonised by a few species from that continent. These species would become modified over time, but would still be related to species found on the continent, and Darwin observed that this was a common pattern. Darwin discussed ways that species could be dispersed across oceans to colonise islands, many of which he had investigated experimentally.<SUP id="cite_ref-161" class="reference"><A href="#cite_note-161">[161]</A></SUP></P>
<P>Chapter XII continues the discussion of biogeography. After a brief discussion of freshwater species, it returns to oceanic islands and their peculiarities; for example on some islands roles played by mammals on continents were played by other animals such as flightless birds or reptiles. The summary of both chapters says:</P>
<BLOCKQUOTE>
<P>... I think all the grand leading facts of geographical distribution are explicable on the theory of migration (generally of the more dominant forms of life), together with subsequent modification and the multiplication of new forms. We can thus understand the high importance of barriers, whether of land or water, which separate our several zoological and botanical provinces. We can thus understand the localisation of sub-genera, genera, and families; and how it is that under different latitudes, for instance in South America, the inhabitants of the plains and mountains, of the forests, marshes, and deserts, are in so mysterious a manner linked together by affinity, and are likewise linked to the extinct beings which formerly inhabited the same continent ... On these same principles, we can understand, as I have endeavoured to show, why oceanic islands should have few inhabitants, but of these a great number should be endemic or peculiar; ...<SUP id="cite_ref-162" class="reference"><A href="#cite_note-162">[162]</A></SUP></P>

<BLOCKQUOTE>
<P>All the foregoing rules and aids and difficulties in classification are explained, if I do not greatly deceive myself, on the view that the natural system is founded on descent with modification; that the characters which naturalists consider as showing true affinity between any two or more species, are those which have been inherited from a common parent, and, in so far, all true classification is genealogical; that community of descent is the hidden bond which naturalists have been unconsciously seeking, ...<SUP id="cite_ref-163" class="reference"><A href="#cite_note-163">[163]</A></SUP></P>

<P>It is interesting to contemplate an entangled bank, clothed with many plants of many kinds, with birds singing on the bushes, with various insects flitting about, and with worms crawling through the damp earth, and to reflect that these elaborately constructed forms, so different from each other, and dependent on each other in so complex a manner, have all been produced by laws acting around us ... Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.<SUP id="cite_ref-168" class="reference"><A href="#cite_note-168">[168]</A></SUP></P>

<P>There were serious scientific objections to the process of <A href="/wiki/Natural_selection" title="Natural selection">natural selection</A> as the key mechanism of evolution, including <A href="/wiki/Karl_Wilhelm_von_N%C3%A4geli" class="mw-redirect" title="Karl Wilhelm von Nägeli">Karl von Nägeli</A>'s insistence that a trivial characteristic with no adaptive advantage could not be developed by selection. Darwin conceded that these could be linked to adaptive characteristics. His estimate that the <A href="/wiki/Age_of_the_Earth" title="Age of the Earth">age of the Earth</A> allowed gradual evolution was disputed by <A href="/wiki/William_Thomson,_1st_Baron_Kelvin" title="William Thomson, 1st Baron Kelvin">William Thomson (later awarded the title Lord Kelvin)</A>, who calculated that it had cooled in less than 100 million years. Darwin accepted <A href="/wiki/Blending_inheritance" title="Blending inheritance">blending inheritance</A>, but <A href="/wiki/Fleeming_Jenkin" title="Fleeming Jenkin">Fleeming Jenkin</A> calculated that as it mixed traits, natural selection could not accumulate useful traits. Darwin tried to meet these objections in the 5th edition. <A href="/wiki/St._George_Jackson_Mivart" title="St. George Jackson Mivart">Mivart</A> supported directed evolution, and compiled scientific and religious objections to natural selection. In response, Darwin made considerable changes to the sixth edition. The problems of the age of the Earth and heredity were only resolved in the 20th century.<SUP id="cite_ref-miv_87-1" class="reference"><A href="#cite_note-miv-87">[87]</A></SUP><SUP id="cite_ref-227" class="reference"><A href="#cite_note-227">[227]</A></SUP></P>
<P>By the mid-1870s, most scientists accepted evolution, but relegated natural selection to a minor role as they believed evolution was purposeful and progressive. The range of evolutionary theories during "<A href="/wiki/The_eclipse_of_Darwinism" title="The eclipse of Darwinism">the eclipse of Darwinism</A>" included forms of "<A href="/wiki/Saltation_(biology)" title="Saltation (biology)">saltationism</A>" in which new species were thought to arise through "jumps" rather than gradual adaptation, forms of <A href="/wiki/Orthogenesis" title="Orthogenesis">orthogenesis</A> claiming that species had an inherent tendency to change in a particular direction, and forms of neo-Lamarckism in which inheritance of acquired characteristics led to progress. The minority view of <A href="/wiki/August_Weismann" title="August Weismann">August Weismann</A>, that natural selection was the only mechanism, was called <A href="/wiki/Neo-Darwinism" title="Neo-Darwinism">neo-Darwinism</A>. It was thought that the rediscovery of <A href="/wiki/Mendelian_inheritance" title="Mendelian inheritance">Mendelian inheritance</A> invalidated Darwin's views.<SUP id="cite_ref-228" class="reference"><A href="#cite_note-228">[228]</A></SUP><SUP id="cite_ref-Quammen205-234_229-0" class="reference"><A href="#cite_note-Quammen205-234-229">[229]</A></SUP></P>

<P>While some, like Spencer, used analogy from natural selection as an argument against government intervention in the economy to benefit the poor, others, including <A href="/wiki/Alfred_Russel_Wallace" title="Alfred Russel Wallace">Alfred Russel Wallace</A>, argued that action was needed to correct social and economic inequities to level the playing field before natural selection could improve humanity further. Some political commentaries, including <A href="/wiki/Walter_Bagehot" title="Walter Bagehot">Walter Bagehot</A>'s <I>Physics and Politics</I> (1872), attempted to extend the idea of natural selection to competition between nations and between human races. Such ideas were incorporated into what was already an ongoing effort by some working in <A href="/wiki/Anthropology" title="Anthropology">anthropology</A> to provide scientific evidence for the superiority of <A href="/wiki/Caucasian_race" title="Caucasian race">Caucasians</A> over non white races and justify European <A href="/wiki/Imperialism" title="Imperialism">imperialism</A>. Historians write that most such political and economic commentators had only a superficial understanding of Darwin's scientific theory, and were as strongly influenced by other concepts about social progress and evolution, such as the Lamarckian ideas of Spencer and Haeckel, as they were by Darwin's work. Darwin objected to his ideas being used to justify military aggression and unethical business practices as he believed morality was part of fitness in humans, and he opposed <A href="/wiki/Polygenism" title="Polygenism">polygenism</A>, the idea that human races were fundamentally distinct and did not share a recent common ancestry.<SUP id="cite_ref-230" class="reference"><A href="#cite_note-230">[230]</A></SUP></P>

But even here it does not matter whether the groups are from different 'races' or from the same race. It is nests of honeybees that compete with each other, and human tribes that compete with other human tribes. For Darwin, the question of group selection had nothing <I>special</I> to do with 'race.' Still, writing in the heyday of empire, Darwin saw European nations outcompeting the nations, kingdoms, and tribes that occupy the rest of the globe. In this one very salient example, Darwin did see races struggling with each other. In any event, the word <I>race</I> in Darwin’s subtitle needs to be understood very broadly; it encompasses competition among individuals, competition among groups in the same 'race,' and competition from groups from different 'races.' This is a much broader meaning than the word 'race' tends to have today."</SPAN></LI>

Accordingly I collected notes on the subject for my own satisfaction, and not for a long time with any intention of publishing. Although in the <I>Origin of Species,</I> the derivation of any particular species is never discussed, yet I thought it best, in order that no honourable man should accuse me of concealing my views, to add that by the work in question 'light would be thrown on the origin of man and his history.' It would have been useless and injurious to the success of the book to have paraded without giving any evidence my conviction with respect to his origin."</SPAN></LI>
