Many of the species are endoparasites in living cells, mostly of algae or fungi , but not exclusively. At least two species of Pseudospora have been taken for reproductive stages in the life history of their hosts—whence indeed the generic name. Plasmodiophora brassicae gives rise to

From 1869 until his death he edited this journal (jointly with his father, 1869–1871). He worked as one of Huxley's team at the new buildings in South Kensington , and after the death of Francis Balfour became Huxley's intended successor. Lankester was appointed Jodrell Professor of Zoology and Comparative Anatomy and curator of what
291-451: A genealogical branching of a single evolutionary tree , in which "It is absurd to talk of one animal being higher than another", thereby discarding Lamarck's idea of independent lineages progressing to higher forms. While developing this intensive study of transmutation, Darwin became mired in more work. Still rewriting his Journal , he took on editing and publishing the expert reports on his collections, and with Henslow's help obtained

In November, the anonymously published sensational best-seller Vestiges of the Natural History of Creation brought wide interest in transmutation. Darwin scorned its amateurish geology and zoology, but carefully reviewed his own arguments. Controversy erupted, and it continued to sell well despite contemptuous dismissal by scientists. Darwin completed his third geological book in 1846. He now renewed

Darwin was unqualified for Cambridge's Tripos exams and was required instead to join the ordinary degree course. He preferred riding and shooting to studying. During the first few months of Darwin's enrolment at Christ's College, his second cousin William Darwin Fox was still studying there. Fox impressed him with his butterfly collection, introducing Darwin to entomology and influencing him to pursue beetle collecting. He did this zealously and had some of his finds published in James Francis Stephens ' Illustrations of British entomology (1829–1932). Through Fox, Darwin became

He stretched the funding to include his planned books on geology, and agreed to unrealistic dates with the publisher. As the Victorian era began, Darwin pressed on with writing his Journal , and in August 1837 began correcting printer's proofs . As Darwin worked under pressure, his health suffered. On 20 September, he had "an uncomfortable palpitation of

In Lankester's time the Natural History Museum had its own building in South Kensington , but in financial and administrative matters it was subordinate to the British Museum . Moreover, the Superintendent (= Director) of the NHM was the subordinate of the Principal Librarian of the BM, a fact which was bound to cause trouble since that august person

Darwin's book The Structure and Distribution of Coral Reefs on his theory of atoll formation was published in May 1842 after more than three years of work, and he then wrote his first "pencil sketch" of his theory of natural selection. To escape the pressures of London, the family moved to rural Down House in Kent in September. On 11 January 1844, Darwin mentioned his theorising to

The survey continued to the south in Patagonia . They stopped at Bahía Blanca , and in cliffs near Punta Alta Darwin made a major find of fossil bones of huge extinct mammals beside modern seashells, indicating recent extinction with no signs of change in climate or catastrophe. He found bony plates like

He later published his view that these were marine-raised beaches, but then had to accept that they were shorelines of a proglacial lake . Fully recuperated, he returned to Shrewsbury in July 1838. Used to jotting down daily notes on animal breeding, he scrawled rambling thoughts about marriage, career and prospects on two scraps of paper, one with columns headed "Marry" and "Not Marry" . Advantages under "Marry" included "constant companion and

He met other leading parson-naturalists who saw scientific work as religious natural theology , becoming known to these dons as "the man who walks with Henslow". When his own exams drew near, Darwin applied himself to his studies and was delighted by the language and logic of William Paley 's Evidences of Christianity (1795). In his final examination in January 1831, Darwin did well, coming tenth out of 178 candidates for

He had some expertise in geology, beetle collecting and dissecting marine invertebrates, but in all other areas, was a novice and ably collected specimens for expert appraisal. Despite suffering badly from seasickness, Darwin wrote copious notes while on board the ship. Most of his zoology notes are about marine invertebrates, starting with plankton collected during

This undoubtedly damaged and limited the second half of his career. Lankester appears, thinly disguised, in several novels. He is the model for Sir Roderick Dover in H. G. Wells ' Marriage (Wells had been one of his students), and in Robert Briffault 's Europa , which contains

In 1847, Hooker read the "Essay" and sent notes that provided Darwin with the calm critical feedback that he needed, but would not commit himself and questioned Darwin's opposition to continuing acts of creation . In an attempt to improve his chronic ill health, Darwin went in 1849 to Dr. James Gully 's Malvern spa and
1649-529: A fortnight mapping strata in Wales. After leaving Sedgwick in Wales, Darwin spent a few days with student friends at Barmouth . He returned home on 29 August to find a letter from Henslow proposing him as a suitable (if unfinished) naturalist for a self-funded supernumerary place on HMS Beagle with captain Robert FitzRoy , a position for a gentleman rather than "a mere collector". The ship

In Darwin's second year at the university, he joined the Plinian Society , a student natural-history group featuring lively debates in which radical democratic students with materialistic views challenged orthodox religious concepts of science. He assisted Robert Edmond Grant 's investigations of

Having decided in favour of marriage, he discussed it with his father, then went to visit his cousin Emma on 29 July. At this time he did not get around to proposing, but against his father's advice, he mentioned his ideas on transmutation. He married Emma on 29 January 1839 and they were
1940-530: A giant capybara . The armour fragments were actually from Glyptodon , a huge armadillo-like creature, as Darwin had initially thought. These extinct creatures were related to living species in South America. In mid-December, Darwin took lodgings in Cambridge to arrange expert classification of his collections, and prepare his own research for publication. Questions of how to combine his diary into

The finds were shipped to England, and scientists found the fossils of great interest. In Patagonia, Darwin came to wrongly believe the territory was devoid of reptiles. On rides with gauchos into the interior to explore geology and collect more fossils, Darwin gained social, political and anthropological insights into both native and colonial people at

Darwin promptly made the long coach journey to Shrewsbury to visit his home and see relatives. He then hurried to Cambridge to see Henslow, who advised him on finding available naturalists to catalogue Darwin's animal collections and to take on the botanical specimens. Darwin's father organised investments, enabling his son to be
2231-410: A majority of the educated public had accepted evolution as a fact . However, many initially favoured competing explanations that gave only a minor role to natural selection, and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution.

Darwin stayed with his freethinking brother Erasmus, part of this Whig circle and a close friend of the writer Harriet Martineau , who promoted the Malthusianism that underpinned the controversial Whig Poor Law reforms to stop welfare from causing overpopulation and more poverty. As a Unitarian, she welcomed the radical implications of transmutation of species , promoted by Grant and younger surgeons influenced by Geoffroy . Transmutation

On the geologically new Galápagos Islands , Darwin looked for evidence attaching wildlife to an older "centre of creation", and found mockingbirds allied to those in Chile but differing from island to island. He heard that slight variations in the shape of tortoise shells showed which island they came from, but failed to collect them, even after eating tortoises taken on board as food. In Australia,

He later called his theory natural selection , an analogy with what he termed the "artificial selection" of selective breeding. On 11 November, he returned to Maer and proposed to Emma, once more telling her his ideas. She accepted, then in exchanges of loving letters she showed how she valued his openness in sharing their differences, while expressing her strong Unitarian beliefs and concerns that his honest doubts might separate them in

From September 1818, he joined his older brother Erasmus in attending the nearby Anglican Shrewsbury School as a boarder . Darwin spent the summer of 1825 as an apprentice doctor, helping his father treat the poor of Shropshire, before going to the well-regarded University of Edinburgh Medical School with his brother Erasmus in October 1825.

Darwin was well-prepared to compare this to Augustin de Candolle 's "warring of the species" of plants and the struggle for existence among wildlife, explaining how numbers of a species kept roughly stable. As species always breed beyond available resources, favourable variations would make organisms better at surviving and passing the variations on to their offspring, while unfavourable variations would be lost.

Around mid-July, he recorded in his "B" notebook his thoughts on lifespan and variation across generations – explaining the variations he had observed in Galápagos tortoises , mockingbirds, and rheas. He sketched branching descent, and then
6984-410: The recapitulative development of the individual. This is the idea propagated by Ernst Haeckel as a source of evolutionary evidence ( recapitulation theory ). As antecedents of degeneration, Lankester lists: He also considered the axolotl , a mole salamander , which can breed whilst still in its gilled larval form without maturing into a terrestrial adult. Lankester noted that this process could take
7081-643: The recapitulative phases of the barnacle , we may doubt whether naturalists would ever have guessed it was a crustacean ." The lizard Seps has limbs which are "ridiculously small", and Bipes , a burrowing lizard, has no front limbs, and rear limbs reduced to stumps. The Dibamidae are legless lizards of tropical forests who also adopt the burrowing habit. Snakes , which have evolved unique forms of locomotion , and are probably derived from lizards. Thus degeneration or retrogressive metamorphosis sometimes occurs as species adapt to changes in habit or way of life. As evidence of degeneration, Lankester identifies
7178-520: The replacement of extinct species by others" as "a natural in contradistinction to a miraculous process". When organising his notes as the ship sailed home, Darwin wrote that, if his growing suspicions about the mockingbirds, the tortoises and the Falkland Islands fox were correct, "such facts undermine the stability of Species", then cautiously added "would" before "undermine". He later wrote that such facts "seemed to me to throw some light on
7275-519: The same idea, prompting the immediate joint submission of both their theories to the Linnean Society of London . Darwin's work established evolutionary descent with modification as the dominant scientific explanation of natural diversification. In 1871, he examined human evolution and sexual selection in The Descent of Man, and Selection in Relation to Sex , followed by The Expression of
7372-408: 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 new species. Here, then, I had at last got a theory by which to work... By mid-December, Darwin saw
7469-402: The subsequent evolution of the race into a totally different and otherwise improbable direction. This idea, which Lankester called super-larvation , is now called neoteny . Lankester extended the idea of degeneration to human societies, which carries little significance today, but it is a good example of a biological concept invading social science. Lankester and H. G. Wells used the idea as
7566-409: The systematics of the taxa. He wrote his first examination of the species in 1846, but did not formally describe it until 1854. FitzRoy's long delayed Narrative was published in May 1839. Darwin's Journal and Remarks got good reviews as the third volume, and on 15 August it was published on its own. Early in 1842, Darwin wrote about his ideas to Charles Lyell, who noted that his ally "denies seeing
7663-473: The voyage made Darwin famous as a popular author. Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations and, in 1838, devised his theory of natural selection. Although he discussed his ideas with several naturalists, he needed time for extensive research, and his geological work had priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay that described
7760-420: The voyage began on 27 December 1831; it lasted almost five years. As FitzRoy had intended, Darwin spent most of that time on land investigating geology and making natural history collections, while HMS Beagle surveyed and charted coasts. He kept careful notes of his observations and theoretical speculations, and at intervals during the voyage his specimens were sent to Cambridge together with letters including
7857-403: The work of earthworms , inspiring "a new & important theory" on their role in soil formation , which Darwin presented at the Geological Society on 1 November 1837. His Journal was printed and ready for publication by the end of February 1838, as was the first volume of the Narrative , but FitzRoy was still working hard to finish his own volume. William Whewell pushed Darwin to take on
7954-644: Was elected a Fellow of the Royal Society (FRS). On 29 January, Darwin and Emma Wedgwood were married at Maer in an Anglican ceremony arranged to suit the Unitarians, then immediately caught the train to London and their new home. Darwin now had the framework of his theory of natural selection "by which to work", as his "prime hobby". His research included extensive experimental selective breeding of plants and animals, finding evidence that species were not fixed and investigating many detailed ideas to refine and substantiate his theory. For fifteen years this work
8051-418: Was a " wren " was in the finch group . Darwin had not labelled the finches by island, but from the notes of others on the ship, including FitzRoy, he allocated species to islands. The two rheas were distinct species, and on 14 March Darwin announced how their distribution changed going southwards. By mid-March 1837, barely six months after his return to England, Darwin was speculating in his Red Notebook on
8148-426: Was an English naturalist , geologist , and biologist , widely known for his contributions to evolutionary biology . His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental scientific concept. In a joint publication with Alfred Russel Wallace , he introduced his scientific theory that this branching pattern of evolution resulted from
8245-619: Was an active member of the Rationalist group associated with the circle of Thomas Huxley , Samuel Laing and others. He was a friend of the Rationalist Edward Clodd of Aldeburgh . From 1901 to his death in 1929 he was Honorary President of the Ipswich Museum . He became convinced of the human workmanship of the (now unfavoured) 'Pre-palaeolithic' implements and rostro-carinates, and championed their cause at
8342-472: Was anathema to Anglicans defending social order, but reputable scientists openly discussed the subject, and there was wide interest in John Herschel's letter praising Lyell's approach as a way to find a natural cause of the origin of new species. Gould met Darwin and told him that the Galápagos mockingbirds from different islands were separate species, not just varieties, and what Darwin had thought
8439-480: Was charged with disorderly conduct and resisting arrest while in the company of a group of female prostitutes on the street, but was acquitted. (It is incorrect, as has been alleged, that the charge concerned homosexual offences.) He died in London on 13 August 1929. A finely decorated memorial plaque to him can be seen at the Golders Green Crematorium , Hoop Lane, London. Lankester became
8536-425: Was in the background to his main occupation of writing on geology and publishing expert reports on the Beagle collections, in particular, the barnacles . The impetus of Darwin's barnacle research came from a collection of a barnacle colony from Chile in 1835, which he dubbed Mr. Arthrobalanus . His confusion over the relationship of this species ( Cryptophialus minutus ) to other barnacles caused him to fixate on
8633-504: Was no unbridgeable gap between humans and animals. A year on, the mission had been abandoned. The Fuegian they had named Jemmy Button lived like the other natives, had a wife, and had no wish to return to England. Darwin experienced an earthquake in Chile in 1835 and saw signs that the land had just been raised, including mussel -beds stranded above high tide. High in the Andes he saw seashells, and several fossil trees that had grown on
8730-451: Was not a scientist. We can see that the conflict which took place was one aspect of the struggle undertaken, in their different ways, by Owen , Hooker , Huxley and Tyndall to emancipate science from enslavement by traditional forces. There was trouble from the moment Lankester put forward his candidature for the office vacated by Sir William Flower , who was on the point of death. The Principal Librarian, Sir Edward Maunde Thompson ,
8827-781: Was one of the first to see its importance: his full acceptance of selection came after reading Weismann's essays, some of which he translated into English. Lankester was hugely influential, though perhaps more as a teacher than as a researcher. Ernst Mayr said "It was Lankester who founded a school of selectionism at Oxford". Those he influenced (in addition to Weldon) included Edwin Stephen Goodrich (Linacre chair in zoology at Oxford 1921–1946) and (indirectly) Julian Huxley (the evolutionary synthesis). In turn their disciples, such as E. B. Ford (ecological genetics), Gavin de Beer (embryology and evolution), Charles Elton (ecology) and Alister Hardy (marine biology) held sway during
8924-577: Was rather bored by Robert Jameson 's natural-history course, which covered geology – including the debate between neptunism and plutonism . He learned the classification of plants and assisted with work on the collections of the University Museum , one of the largest museums in Europe at the time. Darwin's neglect of medical studies annoyed his father, who sent him to Christ's College, Cambridge , in January 1828, to study for
9021-443: Was rounded off by study visits to Vienna , Leipzig and Jena , and he did some work at the Stazione Zoologica at Naples . He took the examination to become a Fellow of Exeter College, Oxford , and studied under Thomas H. Huxley before taking his MA . Lankester therefore had a far better education than most English biologists of the previous generation, such as Huxley , Wallace and Bates . Even so, it could be argued that
9118-849: Was shown by the Archbishop of Canterbury offering him an enhanced pension, and the knighthood that was bestowed on him the next year. The issues raised by this affair did not end there. Eventually the NHM gained, first, its administrative freedom, then finally there was a complete separation from the BM. Today the British Library , the British Museum and the Natural History Museum all occupy separate buildings, and have complete legal, administrative and financial independence from each other. Lankester had close family connections with Suffolk (the Woodbridge and Felixstowe area), and
9215-574: Was surprised to find some benefit from hydrotherapy . Then, in 1851, his treasured daughter Annie fell ill, reawakening his fears that his illness might be hereditary. She died the same year after a long series of crises. In eight years of work on barnacles, Darwin's theory helped him to find " homologies " showing that slightly changed body parts served different functions to meet new conditions, and in some genera he found minute males parasitic on hermaphrodites , showing an intermediate stage in evolution of distinct sexes . In 1853, it earned him
9312-446: Was to leave in four weeks on an expedition to chart the coastline of South America. Robert Darwin objected to his son's planned two-year voyage, regarding it as a waste of time, but was persuaded by his brother-in-law, Josiah Wedgwood II , to agree to (and fund) his son's participation. Darwin took care to remain in a private capacity to retain control over his collection, intending it for a major scientific institution. After delays,
9409-536: Was well known in parasites, and Lankester gave several examples. In Sacculina , a genus of barnacles which is a parasite of crabs , the female is little more than "a sac of eggs, and absorbed nourishment from the juices of its host by root-like processes" (+ wood-engraved illustration). He called this degenerative evolutionary process in parasites retrogressive metamorphosis . Lankester pointed out that retrograde metamorphosis could be seen in many species that were not, strictly speaking, degenerate. "Were it not for
