A visit to the Galapagos Islands in helped Darwin formulate his ideas on natural selection. He found several species of finch adapted to different.
Setting out for the East Indies inhe once again benefited from having already accepted transmutation, so that he was ready to interpret the phenomena he observed in that context. Wallace, like Darwin, needed a mechanism of transmutation, but unlike Darwin he did not delay in publishing his incomplete views.
In he wrote and published in the Annals and Magazine of Natural History what is known as his Sarawak paper. In it he stated that new species come into being near in time and space to allied species, but without supplying a mechanism for their origin. The paper received little public attention. Darwin thought it just another vaguely transmutationist work. The geologist Charles Lyell, however, thought it very important, and said so to Darwin.
And so, Darwin did. Darwin could not, of course, have stolen the idea of natural selection itself from Wallace, for, as we have seen, it had been demonstrably laid out by Darwin almost two decades earlier. Kohnand Kottler have analyzed this concept in some detail. As Kohn notes, Darwin included in this principle several ideas the branching nature of phylogeny, sympatric speciation, interspecific interactions, ecological specialization which, while familiar enough individually, do not to us today seem to form an ineluctable whole.
Kottler argues that in his Ternate paper, Wallace considered only linear or phyletic divergence i. Kohn concludes that Darwin had formulated his principle of divergence by January ; Darwinin his autobiography, implies he had done so by early ; according to Kottler, Darwin had formulated his principle by at the very latest. By any of these datings, Darwin could not have been influenced by the Ternate paper of When Wallace sent his paper, he asked Darwin to pass the paper on to Lyell.
Darwin was much distressed by the paper, as it contained, he thought, his own views in miniature, even though more sober reflection revealed a number of differences in their formulations of the concept Kottler, ; Shermer, Darwin was much distracted at this time by an outbreak of disease in his household, in which several fell ill, and his son Charles Waring died his funeral was on July 1, the day the papers were read at Burlington House.
In presenting them, Lyell and Hooker arranged them, delicately perhaps, in chronological order Burkhardt and Smith, The first of these claims is, as we have already seen, belied by the fact that Darwin had by this time already formulated his principle of divergence. But as Shermer Darwin used to routinely cut up his correspondence, saving relevant portions in topical folders, while discarding the rest, especially beforeand significant parts of what he did save were later lost to water damage Kohn, Again, I think not.
Wallace did not ask that Darwin publish his paper, but that he should show it to Lyell. Darwin, had he wanted to be unfair to Wallace, could easily have read it, sent it on to Lyell, gotten it back, and then returned it to Wallace, with the advice that it was indeed worth publishing, and that if Wallace would revise and return it, he Darwin would submit it forthwith for publication.
Given the delays involved in correspondence with the East Indies, it might have taken six months for such an exchange to occur Raby,giving Darwin ample time to publish his views before Wallace.Darwin and Natural Selection: Crash Course History of Science #22
And if Darwin were so malicious, he could simply have not showed the letter and manuscript to anyone Shermer, Had Wallace been published alone, and received sole credit for natural selection, it would be regarded today as a much more curious and unjust turn of events than what did transpire.
Darwin established that he in fact had thought of natural selection first, and also received a strong stimulus to complete a fuller presentation of his views. The circumstances allowed Wallace to later rightly insist that he not be classed with those forerunners, such as W.
Wallace did see its wide and immensely important applications. Simultaneous publication gave Wallace the nihil obstat of Darwin, Lyell and Hooker, and thus a guarantee that his paper would be read and taken seriously, and not be overlooked, as he thought his Sarawak paper had been. Indeed, over and over again, Wallace expresses his satisfaction and, indeed happiness, over the arrangements made by Hooker and Lyell Shermer, ; van Wyhe, Burkhardt and Smith, Note that Wallace expresses satisfaction at being recognized at all, since the convention of the day was that credit went to the first discoverer rather than the first publisher of the discovery.
Van Wyhe summarizes: They contain only disarming qualifications that the work before the public had not been checked by him in proof. We could not expect a clearer or more unguarded indication of how Wallace received the news of the arrangement than the letter to his mother after learning the news. Hooker and Sir C.
They thought so highly of it they had it immediately read! No matter how many times Wallace said how happy he was with the Linnean arrangement and we have many instancesand how much he thought he benefited more than he deserved, this does not deter some Wallace fans from feeling aggrieved.
Indeed, given how overwhelmingly advantageous the joint publication was for Wallace, it is hard to see how he could have regarded it as anything but positive and fortunate — which is how he described it in all of his later recollections.
In the event, there was little reaction to the Linnean Society papers. Although the circumstances of independent discovery could have led to an ugly dispute about priority, they did not. Although they later differed on a number of issues Kohn, ; Kottler ; Shermerthey remained friends and colleagues for life, standing figuratively side by side, fighting together the intellectual battle for their theory of evolution by natural selection against its many and powerful foes.
During his Cambridge years he did not immerse himself in Theological studies but rather fell in with a set who were keen on fox-hunting and game shooting. He also loved to collect plants, insects, and geological specimens, guided by his cousin William Darwin Fox, an entomologist. He developed a particular interest in collecting beetles, the rarer in species the better. His autobiography quotes one particular beetle hunt in detail: Alas it ejected some intensely acrid fluid, which burnt my tongue so that I was forced to spit the beetle out, which was lost, as well as the third one".
His modest and untrained scientific inclinations were encouraged by Alan Sedgewick, a geologist and also by a botany professor, John Stevens Henslow, who was instrumental, despite heavy paternal opposition, in securing a unpaid place for Darwin as a naturalist on a long term scientific expedition that was to be made by HMS Beagle.
The intended career in the church had, at no time, been explicitly abandoned but his gaining the place on the HMS Beagle meant that he took another path in life. Alfred Russel Wallace was born near Usk, Monmouthshire now part of GwentWales as the eighth child of a family a family, where the father of the family was employed as librarian in Hertford, an English county town not too far distant from London.
Wallace lost much of his remaining property through ill advised dealings in resulting in real hardship for the family - Alfred Russel Wallace, then barely into his teenage years, had to cut short his formal education late in Family contacts in the form of an older brother, William, owning a surveying business led to Wallace embarking on a career as a surveyor where a growing interest in Natural History could also be followed up, to some extent, between daily tasks.
It happened, however, that William Wallace's business fell on hard times causing Wallace to lose his place in He was now successful in gaining a position as a teacher of Surveying in the Collegiate School in Leicester where he had access to a library where there were several reliable books on Natural History. In Wallace made the acquaintance of another young man seriously interested in Natural History named Henry Walter Bateswho although only nineteen years of age, was a well-recognised proficient in the then fashionable pursuit of beetle-collecting and who had already been able to get some scholarly work in Entomology printed in the learned journal, Zoologist.
Other formative developments in his life in these times included attendance at a demonstration of mesmerism - Wallace found that he could himself reproduce the same effects as the mesmerist demonstated and, more seriously, the death of his brother, William, in February which was followed by Wallace returning to surveying and his brother, John, joining him in the business. Wallace found his adminstrative responsibilities particularly arduous.
After the failure of the business Wallace worked as a surveyor in connection with a proposed railway in the Vale of Neath. He also found time to give lectures on science and engineering at the Mechanics' Institute of Neath and to act as a curator of the Neath Philosophical and Literary Institute's museum. His interest in Natural History continued and he entered into a regular correspondence with his friend Henry Bates. During thes times Wallace seems to have read, and to have corresponded with Henry Bates about, Charles Darwin's journal on the Voyage of the Beagle, Charles Lyell's Principles of Geology which offered to demonstrate how long-term change, in Geology in this instance, could be effected through the operation of slow, long-term processes, and an anonomously published work Vestiges of the Natural History of Creation, later known to be by Robert Chamberswhich was an early, popular, and notably controversial effort at arguing pursuasively against both Creationism and Lamarckism as full explanations of the existence of the solar system, the earth, and the diversity of species.
The latter two of these works might be thought to have almost prepared Alfred Russel Wallace's mind for an acceptance of evolutionism. Wallace had read Charles Darwin's book about the Voyage of the Beagle and his admiration for the adventures and the observations of natural phenomena that Darwin wrote about as having occured during the Beagle voyage and also those related in a book by William H.
Edwards entitled A Voyage Up the River Amazon which came into Wallace's hands resulted in his suggesting to his friend Bates that they set themselves up as professional collectors of Natural History specimens to supply the needs of institutions and gentlemen naturalists.
The two young men, they were both in their early twenties, sailed for the mouth of the Amazon in April, In South America Wallace and Bates worked independently of each other with Wallace travelling and collecting samples in the Amazon basin for several years until, earlyill health led him to decide to return home to England.
His activities as a collector of Natural History specimens, and his authorship of academic papers and of his two books that were fairly well received brought him a little bit of notice in the then somewhat fashionable Natural History circles of society and, during these times he became introduced to many interested persons including one Charles Darwin.

Wallace is considered to have been something of a convinced evolutionist but without seeing how such evolution might be driven. In this paper Wallace sets out his "Law" which he claims to have discovered some ten years previously and which he has since then been subject to testing. This possible Law being that: Shortly thereafter Wallace's paper continues: It is evidently possible that two or three distinct species may have had a common antitype, and that each of these may again have become the antitypes from which other closely allied species were created.
This paper was read by Sir Charles Lyell who found its contents to suggest strongly that Species were not fixed creations of God, but were in fact naturally mutable. As a friend of Charles Darwin, who knew that Darwin had been considering the Emergence of Species for a considerable time he subsequently urged Darwin to make efforts to complete his work on related subjects to establish academic priority for his own ideas.
Darwin's work in this area had been on-going for a long time. He had returned from his five years of voyaging and observation on the HMS Beagle in with a newly critical attitude to Biblical explanations of Creation and much personal observation of nature and of the operation of natural forces to consider.
As early as the direction of Darwin's mind can perhaps be illustrated by this famous sketch from his Notebook B dating fromand deemed by editors of Darwin's papers to be concerned with his thoughts about the Transmutation of Specieswhich shows an early attempt at a theoretical insight of how a genus of related species might originate by divergence from a starting point 1: Thus genera would be formed. From Darwin's notebook B now stored in Cambridge University library Late in life Charles Darwin was approached by a publisher who was keen to bring out Darwin's Autobiography.
A section of this work relates another key stage in his development of an inherently persuasive hypothesis about a scenario where there would be a naturally explicable origin of species being his reading, late inof an Essay by the Reverend Thomas Malthus.
Why does Charles Darwin eclipse Alfred Russel Wallace?
To use Charles Darwin's own words from his Autobiography. I happened to read for amusement Malthus on 'Population', and being well prepared to appreciate the struggle for existence which everywhere goes on from long-continued observation of the habits of animals and plants, it at once struck me that under these circumstances favourable variations would tend to be preserved, and unfavourable ones to be destroyed.
The result of this would be the formation of a new species. Here, then, I had at last got a theory by which to work. Darwin continued to develop a theory expaining the naturally arising development of new species but at the same time had begun to think seriously that life as a scholarly bachelor would be unappealing and decided to attempt to pay court to his sincerely religious first cousin, Emma Wedgwood.
By the summer of Emma agreed to marry Charles Darwin, knowing him to hold skeptical views and even wrote to him soon after their engagement telling him that she was sad that "our opinions on the most important subject should differ widely. Darwin had grown up in and, despite his own skepticism after returning from his voyages, continued to live in a society that generally accepted biblical explanations of creation whereby the Earth and all of its unchanging, immutable, life forms were, as they were and as they ever had been, as a result of Original Acts of Divine Creation.

DuringDarwin, with Emma's editorial advice and participation, extended an initial thirty-five page abstract of his theory written in pencil in by preparing a two hundred and thirty page-long overview of his theory for publication in the event of his death. He also framed an accompanying letter to his wife asking her to seek the aid of several of his scientific friends to that end and setting aside a substantial sum to fund the project!
Thus even though he went to the trouble of gathering his thoughts so as to prepare a manuscript overview of his theorising, Darwin actually preferred to keep his potentially most controversial ideas a private matter because of his reluctance to meet an expected adverse reaction from family, friends, and the wider public.
Despite the time and effort put into its preparation the manuscript overview was placed in storage in a securely sealed packet that was labelled 'only to be opened in the event of my death' that Darwin placed in a cupboard under the stairs of Darwin's home!
