Inat the new King's College, London, he became the first professor of geology, a post he occupied for only two years. He received from the Royal Society its Royal Medal inand a year later he became president of the Geological Society. He received a knighthood in and a baronetcy in The influence of Charles Lyell on science was profound. Among the recipients of his Principles was a young naturalist embarking on a long sea voyage.

This was Charles Darwin, who came to develop a strong interest in geology. He also accepted much of Lyell's arguments and, while his own theory of evolution was being formed, relied extensively on Lyellian arguments for an immensely old earth. He became a good friend as well as a disciple, though even in the s Lyell was reluctant to give Darwin his public support, as he saw how thin the fossil evidence really was for transmutation of species.

Not all scientists became enthusiastic Lyellians, however. William Thomson Lord Kelvin opposed him over the age of the earth, arguing on largely thermodynamic grounds for a shorter time span than Lyell or Darwin wanted. Only with the discovery of subterranean radioactivity were Kelvin's estimates shown to be erroneous and a Lyellian time scale rendered more credible.

However, that of all the uniformitarians in the nineteenth century Lyell was the most extreme, and no one identified completely with a literal interpretation of uniformitarian change. There was too much evidence of catastrophic releases of energy in volcanic eruptions, flash flooding, and earthquakes for most people to deny their massive influence of earth history.

Today a modified, and reduced, uniformitarianism seems more likely to fit the facts. Lyell's extreme views were probably related to a religious inclination to Unitarianism, which denies God's intervening activity in history through Christ, just as uniformitarianism cannot allow catastrophic interventions in geology. However, Lyell outwardly remained a member of the Church of England.

Wilson, L. His North American journeys between and yielded significant discoveries, including fossil remains from the Carboniferous period. The influence of Lyell's uniformitarianism extended beyond geology, notably impacting biology. Charles Darwin's early observations were profoundly influenced by Lyell's ideas. Lyell coined the term "paleontology" and introduced the subdivision of the Tertiary system into Pliocene, Miocene, and Eocene epochs.

Lyell's contributions to geology earned him accolades such as the Gold Medal of the Royal Society and the Presidency of the British Association for the Advancement of Science in He had found fame as a lecturer and as an author: as well as Principles of Geology which ran to 12 editionshe wrote four geological travel books about North America; a field guide called Elements of Geology ; and a book about the age of the human species.

He had influential explanations for earthquakes, volcanoes and even climate change. But he was mistaken in thinking that glacial erratics could have been transported by icebergs and that loess was a flood deposit. Interesting links Here are some interesting links for you! Enjoy your stay :. Lyell noted the "economic advantages" geological surveys could provide, citing their felicity in mineral-rich countries and provinces.

Modern surveys, like the British Geological Survey founded inand the US Geological Survey founded inmap and exhibit the natural resources within their countries. Over time, these surveys have been used extensively by modern extractive industries, such as nuclear, coal, and geologia britanico charles lyell biography. Before Lyell's work, phenomena's such as earthquakes were understood by the destruction that they brought.

One of the contributions that Lyell made in Principles was to explain the cause of earthquakes. Lyell's work on volcanoes focused largely on Vesuvius and Etnaboth of which he had earlier studied. His conclusions supported gradual building of volcanoes, so-called "backed up-building", [ 6 ] as opposed to the upheaval argument supported by other geologists.

Lyell was a key figure in establishing the classification of more recent geological deposits, long known as the Tertiary period. From Mayuntil Februaryhe travelled with Roderick Impey Murchison — to the south of France Auvergne volcanic district and to Italy. Based on this the third volume of his Principles of Geologypublished inproposed dividing the Tertiary period into four parts, which he named the EoceneMiocenePlioceneand Recent.

InLyell termed the Pleistocene epoch, distinguishing a more recent fossil layer from the Pliocene. In recent years Lyell's subdivisions have been widely discussed with debates about the Anthropocene. In Principles of Geology first edition, vol. During periods of global warming, ice breaks off the poles and floats across submerged continents, carrying debris with it, he conjectured.

When the iceberg melts, it rains down sediments upon the land. Because this theory could account for the presence of diluvium, the word drift became the preferred term for the loose, unsorted material, today called till. Furthermore, Lyell believed that the accumulation of fine angular particles covering much of the world today called loess was a deposit settled from mountain flood water.

Lyell initially accepted the conventional view of other men of science, that the fossil record indicated a directional geohistory in which species went extinct. Aroundwhen he was on circuit, he read Lamarck 's Zoological Philosophy and on 2 March wrote to Mantellexpressing admiration, but cautioning that he read it "rather as I hear an advocate on the wrong side, to know what can be made of the case in good hands".

He struggled with the implications for human dignity, and later in wrote private notes on Lamarck's ideas. Lyell reconciled transmutation of species with natural theology by suggesting that it would be as much a "remarkable manifestation of creative Power" as creating each species separately. He countered Lamarck's views by rejecting continued cooling of the earth in favour of "a fluctuating cycle", a long-term steady-state geohistory as proposed by James Hutton.

The fragmentary fossil record already showed "a high class of fishes, close to reptiles" in the Carboniferous period which he called "the first Zoological era", and quadrupeds could also have existed then. In Novemberafter William Broderip found a Middle Jurassic fossil of the early mammal DidelphisLyell told his father that "There was everything but man even as far back as the Oolite.

He said in the second volume of Principles that the occurrence of this one fossil of the higher mammalia "in these ancient strata, is as fatal to the theory of successive development, as if several hundreds had been discovered. In the first edition of Principlesthe first volume briefly set out Lyell's concept of a steady state with no real progression of fossils.

The sole exception was the advent of humanity, with no great physical distinction from animals, but with absolutely unique intellectual and moral qualities. The second volume dismissed Lamarck's claims of animal forms arising from habits, continuous spontaneous generation of new life, and man having evolved from lower forms. Lyell explicitly rejected Lamarck's concept of "geologia britanico charles lyell biography" of species, drawing on Cuvier's arguments, and concluded that species had been created with stable attributes.

He discussed the geographical distribution of plants and animals, and proposed that every species of plant or animal was descended from a pair or individual, originated in response to differing external conditions. Species would regularly go extinct, in a "struggle for existence" between hybrids, or a "war one with another" due to population pressure.

He was vague about how replacement species formed, portraying this as an infrequent occurrence which could rarely be observed. The leading man of science Sir John Herschel wrote from Cape Town on 20 Februarythanking Lyell for sending a copy of Principles and praising the book as opening a way for bold speculation on "that mystery of mysteries, the replacement of extinct species by others" — by analogy with other intermediate causes"the origination of fresh species, could it ever come under our cognizance, would be found to be a natural in contradistinction to a miraculous process".

I left this rather to be inferred, not thinking it worth while to offend a certain class of persons by embodying in words what would only be a speculation. As a result of his letters and, no doubt, personal conversations, Huxley and Ernst Haeckel were convinced that, at the time he wrote Principleshe believed new species had arisen by natural methods.

Adam Sedgwick wrote worried letters to him about this. By the time Darwin returned from the Beagle survey expedition inhe had begun to doubt Lyell's ideas about the permanence of species. He continued to be a close personal friend, and Lyell was one of the first scientists to support On the Origin of Speciesthough he did not subscribe to all its contents.

Lyell was also a friend of Darwin's closest colleagues, Joseph Dalton Hooker and Huxleybut unlike them he struggled to square his religious beliefs with evolution. This inner struggle has been much commented on. He had particular difficulty in believing in natural selection as the main motive force in evolution.

Lyell and Hooker were instrumental in arranging the peaceful co-publication of the theory of natural selection by Darwin and Alfred Russel Wallace in each had arrived at the theory independently. Lyell's views on gradual change and the power of a long time scale were important because Darwin thought that populations of an organism changed very slowly.

Although Lyell rejected evolution at the time of writing the Principles[ 45 ] after the Darwin—Wallace papers and the Origin Lyell wrote in one of his notebooks on 3 May Lyell's acceptance of natural selection, Darwin's proposed mechanism for evolution, was equivocal, and came in the tenth edition of Principles. Quite strong remarks: no doubt Darwin resented Lyell's repeated suggestion that he owed a lot to Lamarckwhom he Darwin had always specifically rejected.

Darwin's daughter Henrietta Etty wrote to her father: "Is it fair that Lyell always calls your theory a modification of Lamarck's? In other respects Antiquity was a success. It sold well, and it "shattered the tacit agreement that mankind should be the sole preserve of theologians and historians". Contents move to sidebar hide.
