Biography

Jean Léopold Nicolas Frédéric Cuvier was born in Montbéliard on 23 August 1769. His family had originally come from a village in the Jura that bore the name Cuvier, and had settled in Montbéliard during the Reformation. His mother was Anne Clémence Chatel; his father, Jean-Georges Cuvier, was a lieutenant in the Swiss Guards and a bourgeois of the town of Montbéliard. At the time, the town, which would be annexed to France on 10 October 1793, belonged to the Sovereign County of Montbéliard (in personal union with the Duchy of Württemberg). His mother, who was much younger than his father, tutored him diligently throughout his early years, so he easily surpassed the other children at school. During his gymnasium years, he had little trouble acquiring Latin and Greek, and was always at the head of his class in mathematics, history, and geography. According to Lee, "The history of mankind was, from the earliest period of his life, a subject of the most indefatigable application; and long lists of sovereigns, princes, and the driest chronological facts, once arranged in his memory, were never forgotten."

At the age of 10, soon after entering the gymnasium, he encountered a copy of Conrad Gessner's Historiae Animalium, the work that first sparked his interest in natural history. He then began frequent visits to the home of a relative, where he could borrow volumes of the Comte de Buffon's massive Histoire Naturelle. All of these he read and reread, retaining so much of the information, that by the age of 12, "he was as familiar with quadrupeds and birds as a first-rate naturalist." He remained at the gymnasium for four years.

Cuvier spent an additional four years at the Caroline Academy in Stuttgart, where he excelled in all of his coursework. Although he knew no German on his arrival, after only nine months of study, he managed to win the school prize for that language. Cuvier's German education exposed him to the work of the geologist Abraham Gottlob Werner (1750–1817), whose Neptunism and emphasis on the importance of rigorous, direct observation of three-dimensional, structural relationships of rock formations to geological understanding provided models for Cuvier's scientific theories and methods.

Upon graduation, he had no money on which to live as he awaited an appointment to an academic office. So in July 1788, he took a job at Fiquainville chateau in Normandy as tutor to the only son of the Comte d'Héricy, a Protestant noble. There, during the early 1790s, he began his comparisons of fossils with extant forms. Cuvier regularly attended meetings held at the nearby town of Valmont for the discussion of agricultural topics. There, he became acquainted with Henri Alexandre Tessier (1741–1837), who had assumed a false identity. Previously, he had been a physician and well-known agronomist, who had fled the Terror in Paris. After hearing Tessier speak on agricultural matters, Cuvier recognized him as the author of certain articles on agriculture in the Encyclopédie Méthodique and addressed him as M. Tessier.

Tessier replied in dismay, "I am known, then, and consequently lost."—"Lost!" replied M. Cuvier, "no; you are henceforth the object of our most anxious care." They soon became intimate and Tessier introduced Cuvier to his colleagues in Paris"I have just found a pearl in the dunghill of Normandy", he wrote his friend Antoine-Augustin Parmentier. As a result, Cuvier entered into correspondence with several leading naturalists of the day and was invited to Paris. Arriving in the spring of 1795, at the age of 26, he soon became the assistant of Jean-Claude Mertrud (1728–1802), who had been appointed to the chair of Animal Anatomy at the Jardin des Plantes. When Mertrud died in 1802, Cuvier replaced him in office and the Chair changed its name to Chair of Comparative Anatomy.

The Institut de France was founded in the same year, and he was elected a member of its Academy of Sciences. On 4 April 1796 he began to lecture at the École Centrale du Pantheon and, at the opening of the National Institute in April, he read his first paleontological paper, which subsequently was published in 1800 under the title Mémoires sur les espèces d'éléphants vivants et fossiles. In this paper, he analyzed skeletal remains of Indian and African elephants, as well as mammoth fossils, and a fossil skeleton known at that time as the "Ohio animal". In his second paper in 1796, he described and analyzed a large skeleton found in Paraguay, which he would name Megatherium. He concluded this skeleton represented yet another extinct animal and, by comparing its skull with living species of tree-dwelling sloths, that it was a kind of ground-dwelling giant sloth.

Together, these two 1796 papers were a seminal or landmark event, becoming a turning point in the history of paleontology, and in the development of comparative anatomy, as well. They also greatly enhanced Cuvier's personal reputation and they essentially ended what had been a long-running debate about the reality of extinction.

In 1799, he succeeded Daubenton as professor of natural history in the Collège de France. In 1802, he became titular professor at the Jardin des Plantes; and in the same year, he was appointed commissary of the institute to accompany the inspectors general of public instruction. In this latter capacity, he visited the south of France, but in the early part of 1803, he was chosen permanent secretary of the department of physical sciences of the Academy, and he consequently abandoned the earlier appointment and returned to Paris.

On 2 February 1804, he married Anne Marie Sophie Loquet de Trazay (1768-1849), widow of Louis Philippe Alexandre Duvaucel, Marquis de Castelnau, who had been guillotined in 1794 for being a member of the ferme générale. They had four children, three of whom died in infancy. Their youngest child, Clémentine, died aged 18 in 1827. Cuvier thus outlived all his biological children, but grew close to his stepdaughter Sophie Duvaucel, a highly-accomplished intellectual and artist in her own right, who assisted him in his researches and lectures.

In 1806, he became a foreign member of the Royal Society, and in 1812, a foreign member of the Royal Swedish Academy of Sciences. In 1812, he became a correspondent for the Royal Institute of the Netherlands, and became a member in 1827. Cuvier was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1822.

Cuvier then devoted himself more especially to three lines of inquiry: (i) the structure and classification of the Mollusca; (ii) the comparative anatomy and systematic arrangement of the fishes; (iii) fossil mammals and reptiles and, secondarily, the osteology of living forms belonging to the same groups.

In 1812, Cuvier made what the cryptozoologist Bernard Heuvelmans called his "Rash dictum": he remarked that it was unlikely that any large animal remained undiscovered. Ten years after his death, the word "dinosaur" would be coined by Richard Owen in 1842.

During his lifetime, Cuvier served as an imperial councillor under Napoleon, president of the Council of Public Instruction and chancellor of the university under the restored Bourbons, Grand Officer of the Legion of Honour, a Peer of France, Minister of the Interior, and president of the Council of State under Louis Philippe. He was eminent in all these capacities, and yet the dignity given by such high administrative positions was as nothing compared to his leadership in natural science.

Cuvier was by birth, education, and conviction a devout Lutheran, and remained Protestant throughout his life while regularly attending church services. Despite this, he regarded his personal faith as a private matter; he evidently identified himself with his confessional minority group when he supervised governmental educational programs for Protestants. He also was very active in founding the Parisian Biblical Society in 1818, where he later served as a vice president. From 1822 until his death in 1832, Cuvier was Grand Master of the Protestant Faculties of Theology of the French University.

Opposition to evolution

Cuvier was critical of theories of evolution, in particular those proposed by his contemporaries Lamarck and Geoffroy Saint-Hilaire, which involved the gradual transmutation of one form into another. He repeatedly emphasized that his extensive experience with fossil material indicated one fossil form does not, as a rule, gradually change into a succeeding, distinct fossil form. A deep-rooted source of his opposition to the gradual transformation of species was his goal of creating an accurate taxonomy based on principles of comparative anatomy. Such a project would become impossible if species were mutable, with no clear boundaries between them. According to the University of California Museum of Paleontology, "Cuvier did not believe in organic evolution, for any change in an organism's anatomy would have rendered it unable to survive. He studied the mummified cats and ibises that Geoffroy had brought back from Napoleon's invasion of Egypt, and showed they were no different from their living counterparts; Cuvier used this to support his claim that life forms did not evolve over time."

He also observed that Napoleon's expedition to Egypt had retrieved animals mummified thousands of years previously that seemed no different from their modern counterparts. "Certainly", Cuvier wrote, "one cannot detect any greater difference between these creatures and those we see, than between the human mummies and the skeletons of present-day men."

Lamarck dismissed this conclusion, arguing that evolution happened much too slowly to be observed over just a few thousand years. Cuvier, however, in turn criticized how Lamarck and other naturalists conveniently introduced hundreds of thousands of years "with a stroke of a pen" to uphold their theory. Instead, he argued that one may judge what a long time would produce only by multiplying what a lesser time produces. Since a lesser time produced no organic changes, neither, he argued, would a much longer time. Moreover, his commitment to the principle of the correlation of parts caused him to doubt that any mechanism could ever gradually modify any part of an animal in isolation from all the other parts (in the way Lamarck proposed), without rendering the animal unable to survive.

In his Éloge de M. de Lamarck (Praise for M. de Lamarck), Cuvier wrote that Lamarck's theory of evolution rested on two arbitrary suppositions; the one, that it is the seminal vapour which organizes the embryo; the other, that efforts and desires may engender organs. A system established on such foundations may amuse the imagination of a poet; a metaphysician may derive from it an entirely new series of systems; but it cannot for a moment bear the examination of anyone who has dissected a hand, a viscus, or even a feather.

Instead, he said, the typical form makes an abrupt appearance in the fossil record, and persists unchanged to the time of its extinction. Cuvier attempted to explain this paleontological phenomenon he envisioned (which would be readdressed more than a century later by "punctuated equilibrium") and to harmonize it with the Bible. He attributed the different time periods he was aware of as intervals between major catastrophes, the last of which is found in Genesis.

Cuvier's claim that new fossil forms appear abruptly in the geological record and then continue without alteration in overlying strata was used by later critics of evolution to support creationism, to whom the abruptness seemed consistent with special divine creation (although Cuvier's finding that different types made their paleontological debuts in different geological strata clearly did not). The lack of change was consistent with the supposed sacred immutability of "species", but, again, the idea of extinction, of which Cuvier was the great proponent, obviously was not.

Many writers have unjustly accused Cuvier of obstinately maintaining that fossil human beings could never be found. In his Essay on the Theory of the Earth, he did say, "no human bones have yet been found among fossil remains", but he made it clear exactly what he meant: "When I assert that human bones have not been hitherto found among extraneous fossils, I must be understood to speak of fossils, or petrifactions, properly so called". Petrified bones, which have had time to mineralize and turn to stone, are typically far older than bones found to that date. Cuvier's point was that all human bones found that he knew of, were of relatively recent age because they had not been petrified and had been found only in superficial strata. He was not dogmatic in this claim, however; when new evidence came to light, he included in a later edition an appendix describing a skeleton that he freely admitted was an "instance of a fossil human petrifaction".

The harshness of his criticism and the strength of his reputation, however, continued to discourage naturalists from speculating about the gradual transmutation of species, until Charles Darwin published On the Origin of Species more than two decades after Cuvier's death.

Extinction

Early in his tenure at the National Museum in Paris, Cuvier published studies of fossil bones in which he argued that they belonged to large, extinct quadrupeds. His first two such publications were those identifying mammoth and mastodon fossils as belonging to extinct species rather than modern elephants and the study in which he identified the Megatherium as a giant, extinct species of sloth. His primary evidence for his identifications of mammoths and mastodons as separate, extinct species was the structure of their jaws and teeth. His primary evidence that the Megatherium fossil had belonged to a massive sloth came from his comparison of its skull with those of extant sloth species.

Cuvier wrote of his paleontological method that "the form of the tooth leads to the form of the condyle, that of the scapula to that of the nails, just as an equation of a curve implies all of its properties; and, just as in taking each property separately as the basis of a special equation we are able to return to the original equation and other associated properties, similarly, the nails, the scapula, the condyle, the femur, each separately reveal the tooth or each other; and by beginning from each of them the thoughtful professor of the laws of organic economy can reconstruct the entire animal."

However, Cuvier's actual method was heavily dependent on the comparison of fossil specimens with the anatomy of extant species in the necessary context of his vast knowledge of animal anatomy and access to unparalleled natural history collections in Paris. This reality, however, did not prevent the rise of a popular legend that Cuvier could reconstruct the entire bodily structures of extinct animals given only a few fragments of bone.

At the time Cuvier presented his 1796 paper on living and fossil elephants, it was still widely believed that no species of animal had ever become extinct. Authorities such as Buffon had claimed that fossils found in Europe of animals such as the woolly rhinoceros and the mammoth were remains of animals still living in the tropics (i.e. rhinoceros and elephants), which had shifted out of Europe and Asia as the earth became cooler.

Thereafter, Cuvier performed a pioneering research study on some elephant fossils excavated around Paris. The bones he studied, however, were remarkably different from the bones of elephants currently thriving in India and Africa. This discovery led Cuvier to denounce the idea that fossils came from those that are currently living. The idea that these bones belonged to elephants living – but hiding – somewhere on Earth seemed ridiculous to Cuvier, because it would be nearly impossible to miss them due to their enormous size. The Megatherium provided another compelling data point for this argument. Ultimately, his repeated identification of fossils as belonging to species unknown to man, combined with mineralogical evidence from his stratigraphical studies in Paris, drove Cuvier to the proposition that the abrupt changes the Earth underwent over a long period of time caused some species to go extinct.

Cuvier's theory on extinction has met opposition from other notable natural scientists like Darwin and Charles Lyell. Unlike Cuvier, they didn't believe that extinction was a sudden process; they believed that like the Earth, animals collectively undergo gradual change as a species. This differed widely from Cuvier's theory, which seemed to propose that animal extinction was catastrophic.

However, Cuvier's theory of extinction is still justified in the case of mass extinctions that occurred in the last 600 million years, when approximately half of all living species went completely extinct within a short geological span of two million years, due in part by volcanic eruptions, asteroids, and rapid fluctuations in sea level. At this time, new species rose and others fell, precipitating the arrival of human beings.

Cuvier's early work demonstrated conclusively that extinction was indeed a credible natural global process. Cuvier's thinking on extinctions was influenced by his extensive readings in Greek and Latin literature; he gathered every ancient report known in his day relating to discoveries of petrified bones of remarkable size in the Mediterranean region.

Influence on Cuvier's theory of extinction was his collection of specimens from the New World, many of them obtained from Native Americans. He also maintained an archive of Native American observations, legends, and interpretations of immense fossilized skeletal remains, sent to him by informants and friends in the Americas. He was impressed that most of the Native American accounts identified the enormous bones, teeth, and tusks as animals of the deep past that had been destroyed by catastrophe.

Catastrophism

Cuvier came to believe that most, if not all, the animal fossils he examined were remains of species that had become extinct. Near the end of his 1796 paper on living and fossil elephants, he said:

All of these facts, consistent among themselves, and not opposed by any report, seem to me to prove the existence of a world previous to ours, destroyed by some kind of catastrophe.

Contrary to many natural scientists' beliefs at the time, Cuvier believed that animal extinction was not a product of anthropogenic causes. Instead, he proposed that humans were around long enough to indirectly maintain the fossilized records of ancient Earth. He also attempted to verify the water catastrophe by analyzing records of various cultural backgrounds. Though he found many accounts of the water catastrophe unclear, he did believe that such an event occurred at the brink of human history nonetheless.

This led Cuvier to become an active proponent of the geological school of thought called catastrophism, which maintained that many of the geological features of the earth and the history of life could be explained by catastrophic events that had caused the extinction of many species of animals. Over the course of his career, Cuvier came to believe there had not been a single catastrophe, but several, resulting in a succession of different faunas. He wrote about these ideas many times, in particular, he discussed them in great detail in the preliminary discourse (an introduction) to a collection of his papers, Recherches sur les ossements fossiles de quadrupèdes (Researches on quadruped fossil bones), on quadruped fossils published in 1812.

Cuvier's own explanation for such a catastrophic event is derived from two different sources, including those from Jean-André Deluc and Déodat de Dolomieu. The former proposed that the continents existing ten millennia ago collapsed, allowing the ocean floors to rise higher than the continental plates and become the continents that now exist today. The latter proposed that a massive tsunami hit the globe, leading to mass extinction. Whatever the case was, he believed that the deluge happened quite recently in human history. In fact, he believed that Earth's existence was limited and not as extended as many natural scientists, like Lamarck, believed it to be.

Much of the evidence he used to support his catastrophist theories has been taken from his fossil records. He strongly suggested that the fossils he found were evidence of the world's first reptiles, followed chronologically by mammals and humans. Cuvier didn't wish to delve much into the causation of all the extinction and introduction of new animal species but rather focused on the sequential aspects of animal history on Earth. In a way, his chronological dating of Earth's history somewhat reflected Lamarck's transformationist theories.

Cuvier also worked alongside Alexandre Brongniart in analyzing the Parisian rock cycle. Using stratigraphical methods, they were both able to extrapolate key information regarding Earth history from studying these rocks. These rocks contained remnants of molluscs, bones of mammals, and shells. From these findings, Cuvier and Brongniart concluded that many environmental changes occurred in quick catastrophes, though Earth itself was often placid for extended periods of time in between sudden disturbances.

The 'Preliminary Discourse' became very well known and, unauthorized translations were made into English, German, and Italian (and in the case of those in English, not entirely accurately). In 1826, Cuvier published a revised version under the name, Discours sur les révolutions de la surface du globe (Discourse on the upheavals of the surface of the globe).

After Cuvier's death, the catastrophic school of geological thought lost ground to uniformitarianism, as championed by Charles Lyell and others, which claimed that the geological features of the earth were best explained by currently observable forces, such as erosion and volcanism, acting gradually over an extended period of time. The increasing interest in the topic of mass extinction starting in the late twentieth century, however, has led to a resurgence of interest among historians of science and other scholars in this aspect of Cuvier's work.

Principle of the correlation of parts

In a 1798 paper on the fossil remains of an animal found in some plaster quarries near Paris, Cuvier states what is known as the principle of the correlation of parts. He writes:

If an animal's teeth are such as they must be, in order for it to nourish itself with flesh, we can be sure without further examination that the whole system of its digestive organs is appropriate for that kind of food, and that its whole skeleton and locomotive organs, and even its sense organs, are arranged in such a way as to make it skillful at pursuing and catching its prey. For these relations are the necessary conditions of existence of the animal; if things were not so, it would not be able to subsist.

This idea is referred to as Cuvier's principle of correlation of parts, which states that all organs in an animal's body are deeply interdependent. Species' existence relies on the way in which these organs interact. For example, a species whose digestive tract is best suited to digesting flesh but whose body is best suited to foraging for plants cannot survive. Thus in all species, the functional significance of each body part must be correlated to the others, or else the species cannot sustain itself.

Cuvier believed that the power of his principle came in part from its ability to aid in the reconstruction of fossils. In most cases, fossils of quadrupeds were not found as complete, assembled skeletons, but rather as scattered pieces that needed to be put together by anatomists. To make matters worse, deposits often contained the fossilized remains of several species of animals mixed together. Anatomists reassembling these skeletons ran the risk of combining remains of different species, producing imaginary composite species. However, by examining the functional purpose of each bone and applying the principle of correlation of parts, Cuvier believed that this problem could be avoided.

This principle's ability to aid in the reconstruction of fossils was also helpful to Cuvier's work in providing evidence in favour of extinction. The strongest evidence Cuvier could provide in favour of extinction would be to prove that the fossilized remains of an animal belonged to a species that no longer existed. By applying Cuvier's principle of correlation of parts, it would be easier to verify that a fossilized skeleton had been authentically reconstructed, thus validating any observations drawn from comparing it to skeletons of existing species.

In addition to helping anatomists reconstruct fossilized remains, Cuvier believed that his principle also held enormous predictive power. For example, when he discovered a fossil that resembled a marsupial in the gypsum quarries of Montmartre, he correctly predicted that the fossil would contain bones commonly found in marsupials in its pelvis as well.

Cuvier hoped that his principles of anatomy would provide the law-based framework that would elevate natural history to the truly scientific level occupied by physics and chemistry thanks to the laws established by Isaac Newton (1643 – 1727) and Antoine Lavoisier (1743 – 1794), respectively. He expressed confidence in the introduction to Le Règne Animal that someday anatomy would be expressed as laws as simple, mathematical, and predictive as Newton's laws of physics, and he viewed his principle as an important step in that direction. To him, the predictive capabilities of his principles demonstrated in his prediction of the existence of marsupial pelvic bones in the gypsum quarries of Montmartre demonstrated that these goals were not only in reach, but imminent.

The principle of correlation of parts was also Cuvier's way of understanding function in a non-evolutionary context, without invoking a divine creator. In the same 1798 paper on the fossil remains of an animal found in plaster quarries near Paris, Cuvier emphasizes the predictive power of his principle, writing,

Today comparative anatomy has reached such a point of perfection that, after inspecting a single bone, one can often determine the class, and sometimes even the genus of the animal to which it belonged, above all if that bone belonged to the head or the limbs ... This is because the number, direction, and shape of the bones that compose each part of an animal's body are always in a necessary relation to all the other parts, in such a way that—up to a point—one can infer the whole from any one of them and vice versa.

Though Cuvier believed that his principle's major contribution was that it was a rational, mathematical way to reconstruct fossils and make predictions, in reality, it was difficult for Cuvier to use his principle. The functional significance of many body parts was still unknown at the time, and so relating those body parts to other body parts using Cuvier's principle was impossible. Though Cuvier was able to make accurate predictions about fossil finds, in practice, the accuracy of his predictions came not from application of his principle, but rather from his vast knowledge of comparative anatomy. However, despite Cuvier's exaggerations of the power of his principle, the basic concept is central to comparative anatomy and paleontology.

Comparative anatomy and classification

At the Paris Museum, Cuvier furthered his studies on the anatomical classification of animals. He believed that classification should be based on how organs collectively function, a concept he called functional integration. Cuvier reinforced the idea of subordinating less vital body parts to more critical organ systems as part of anatomical classification. He included these ideas in his 1817 book, The Animal Kingdom.

In his anatomical studies, Cuvier believed function played a bigger role than form in the field of taxonomy. His scientific beliefs rested in the idea of the principles of the correlation of parts and of the conditions of existence. The former principle accounts for the connection between organ function and its practical use for an organism to survive. The latter principle emphasizes the animal's physiological function in relation to its surrounding environment. These findings were published in his scientific readings, including Leçons d'anatomie comparée (Lessons on Comparative Anatomy) between 1800 and 1805, and The Animal Kingdom in 1817.

Ultimately, Cuvier developed four embranchements, or branches, through which he classified animals based on his taxonomical and anatomical studies. He later performed groundbreaking work in classifying animals in vertebrate and invertebrate groups by subdividing each category. For instance, he proposed that the invertebrates could be segmented into three individual categories, including Mollusca, Radiata, and Articulata. He also articulated that species cannot move across these categories, a theory called transmutation. He reasoned that organisms cannot acquire or change their physical traits over time and still retain optimal survival. As a result, he often conflicted with Geoffroy Saint-Hilaire and Jean-Baptiste Lamarck's theories of transmutation.

In 1798, Cuvier published his first independent work, the Tableau élémentaire de l'histoire naturelle des animaux, which was an abridgement of his course of lectures at the École du Pantheon and may be regarded as the foundation and first statement of his natural classification of the animal kingdom.

Racial studies

Cuvier was a Protestant and a believer in monogenism, who held that all men descended from the biblical Adam, although his position usually was confused as polygenist. Some writers who have studied his racial work have dubbed his position as "quasi-polygenist", and most of his racial studies have influenced scientific racism. Cuvier believed there were three distinct races: the Caucasian (white), Mongolian (yellow), and the Ethiopian (black). Cuvier claimed that Adam and Eve were Caucasian, the original race of mankind. The other two races originated from survivors escaping in different directions after a major catastrophe hit the earth 5,000 years ago, with those survivors then living in complete isolation from each other.

Cuvier categorized these divisions he identified into races according to his perception of the beauty or ugliness of their skulls and the quality of their civilizations. Cuvier's racial studies held the supposed features of polygenism, namely fixity of species; limits on environmental influence; unchanging underlying type; anatomical and cranial measurement differences in races; and physical and mental differences between distinct races.

Alongside other French naturalists, Cuvier subjected Sarah Baartman, a South African Khokhoi woman exhibited in European freak shows as the "Hottentot Venus", to examinations. At the time that Cuvier interacted with Baartman, Baartman's "existence was really quite miserable and extraordinarily poor. Sara was literally [sic] treated like an animal." In 1815, while Baartman was very ill, Cuvier commissioned a nude painting of her. She died shortly afterward, aged 26.

Following Baartman's death, Cuvier sought out and received permission to dissect her body, focusing on her genitalia, buttocks and skull shape. In his examination, Cuvier concluded that many of Baartman's features more closely resembled the anatomy of a monkey than a human. Her remains were displayed in the Musée de l'Homme in Paris until 1970, then were put into storage. Her remains were returned to South Africa in 2002.
