ernst haeckel contribution

Ernst Haeckel was a renowned German biologist, naturalist, physician, philosopher and artist who identified many new species of living beings and gave names to thousands of them. He is most well known for his descriptions of phylogenetic trees, studies of radiolarians, and illustrations of vertebrate embryos to support his biogenetic law and Darwin’s work with evolution. Ernst Haeckel, scientist, philosopher and artist, made a significant contribution to early evolutionary theory, and was profoundly influential on the Fine and Decorative Arts of his time. A staunch evolutionary biologist, Haeckel put Darwin on the world map. He became a key figure in social darwinism and leading proponent of scientific racism, stating for instance:[34]. One of his more revolutionary claims was that life was created by chance in the deep sea through random combinations of basic elements like carbon, oxygen, and sulfur. Modern scientists and science historians have varied on the value of these diagrams … [73] Alfred Ploetz, founder of the German Society for Racial Hygiene, praised Haeckel repeatedly, and invited him to become an honorary member. [46]:270–274, The book sold very well, and while some anatomical experts hostile to Haeckel's evolutionary views expressed some private concerns that certain figures had been drawn rather freely, the figures showed what they already knew about similarities in embryos. This is so because the growing embryo needs a constant supply of oxygen, and nutrients. For a time he practiced medicine; his father then agreed to his traveling to Italy, where he painted and even considered art as a career. [52][53] There were multiple versions of the embryo drawings, and Haeckel rejected the claims of fraud. Haeckel was included by name as a forbidden author. 46 Issue 2, p123 . In the United States, Mount Haeckel, a 13,418 ft (4,090 m) summit in the Eastern Sierra Nevada, overlooking the Evolution Basin, is named in his honour, as is another Mount Haeckel, a 2,941 m (9,649 ft) summit in New Zealand; and the asteroid 12323 Haeckel. Haeckel retired from teaching in 1909, and in 1910 he withdrew from the Evangelical Church of Prussia. Review (2002), 77, pp. While he was a student, his professor Johannes Müller, took him on a summer field trip to observe small sea creatures off the coast of Heligoland in the North Sea, sparking his life-long fascination for natural forms and biology. This - in German - is how evolutionary biologist Ernst Haeckel became the first person to define the term ecology in his work published in 1866, entitled "General Morphology of Organisms". https://www.britannica.com/biography/Ernst-Haeckel, Strange Science - Biography of Ernst Haeckel, University of California, Berkeley: Museum of Paleontology - Ernst Haeckel (1834-1919), How Stuff Works - Science - Biography of Ernst Heinrich Haeckel. This group lasted until 1933 and included such notable members as Wilhelm Ostwald, Georg von Arco (1869-1940), Helene Stöcker and Walter Arthur Berendsohn. Haeckel argued that humans were closely related to the primates of Southeast Asia and rejected Darwin's hypothesis of Africa. [25], Haeckel advanced a version of the earlier recapitulation theory previously set out by Étienne Serres in the 1820s and supported by followers of Étienne Geoffroy Saint-Hilaire including Robert Edmond Grant. [77] He was also a pacifist until the First World War, when he wrote propaganda in favor of the war. Relating different images on a grid conveyed a powerful evolutionary message. The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of animals and sea creatures, collected in his Kunstformen der Natur ("Art Forms of Nature"). On one hand, Haeckel was an advocate of scientific racism. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Ernst Heinrich Philipp August Haeckel was a prominent comparative anatomist and active lecturer in the late nineteenth and early twentieth centuries. [50] Others joined in: both expert anatomists and Catholic priests and supporters were politically opposed to Haeckel's views. His chief interests lay in evolution and life development processes in general, including development of nonrandom form, which culminated in the beautifully illustrated Kunstformen der Natur (Art forms of nature). He was giving successful "popular lectures" on his ideas to students and townspeople in Jena, in an approach pioneered by his teacher Rudolf Virchow. Affiliations He was also a philosopher and physician, but in those fields he is not regarded as particularly notable. Together with Hermann Steudner he attended botanylectures in Würzburg. An effective popularizer of science, Haeckel produced numerous tree diagrams, showing evolutionary relationships between different species. In particular, "one and the same, moreover incorrectly interpreted woodcut, is presented to the reader three times in a row and with three different captions as [the] embryo of the dog, the chick, [and] the turtle". [21], Haeckel's affinity for the German Romantic movement, coupled with his acceptance of a form of Lamarckism, influenced his political beliefs. Though Haeckel's views had attracted continuing controversy, there had been little dispute about the embryos and he had many expert supporters, but Wilhelm His revived the earlier criticisms and introduced new attacks on the 1874 illustrations. Reynolds, Andrew // History of Science;Jun2008, Vol. From p. 215: CS1 maint: multiple names: authors list (. Vol. For a fuller list of works of and about Haeckel, see his entry in the German Wikisource. It was frequently reprinted until 1926. ), German zoologist and evolutionist who was a strong proponent of Darwinism and who proposed new notions of the evolutionary descent of human beings. He left the Lutheran church in 1910. He described these theoretical remains in great detail and even named the as-yet unfound species, Pithecanthropus alalus, and instructed his students such as Richard and Oskar Hertwig to go and find it. [13], In 1864, his beloved first wife, Anna Sethe, died. [48] Haeckel disregarded such caution, and in a year wrote his massive and ambitious Generelle Morphologie, published in 1866, presenting a revolutionary new synthesis of Darwin's ideas with the German tradition of Naturphilosophie going back to Goethe and with the progressive evolutionism of Lamarck in what he called Darwinismus. For example, Haeckel described and named hypothetical ancestral microorganisms that have never been found. "Haeckel's Monism and the Birth of Fascist Ideology". It was agreed by all European evolutionists that all vertebrates looked very similar at an early stage, in what was thought of as a common ideal type, but there was a continuing debate from the 1820s between the Romantic recapitulation theory that human embryos developed through stages of the forms of all the major groups of adult animals, literally manifesting a sequence of organisms on a linear chain of being, and Karl Ernst von Baer's opposing view, stated in von Baer's laws of embryology, that the early general forms diverged into four major groups of specialised forms without ever resembling the adult of another species, showing affinity to an archetype but no relation to other types or any transmutation of species. In 1852 Haeckel completed studies at the Domgymnasium, the cathedral high-school of Merseburg. [71] As an advocate of eugenics, he also believed that about 200,000 mentally and congenitally ill should be killed by a medical control board. He invented new terms, including ontogeny and phylogeny, to present his evolutionised recapitulation theory that "ontogeny recapitulated phylogeny". Haeckel tended to speculate, and for some years, he pondered the problem of heredity. In contrast to most of Darwin's supporters, Haeckel put forward a doctrine of evolutionary polygenism based on the ideas of the linguist August Schleicher, in which several different language groups had arisen separately from speechless prehuman Urmenschen (German: proto-humans), which themselves had evolved from simian ancestors. Daniel Gasman (1998). [13] [15], From 1866 to 1867 Haeckel made an extended journey to the Canary Islands with Hermann Fol. The article focuses on the life and contribution of zoologist Ernst Haeckel to the discovery of multi-cellular organisms. "While some criticisms of the drawings are legitimate, others are more tendentious", Richardson and Keuck "Haeckel's ABC of evolution and development". [70] He was also a social Darwinist who believed that "survival of the fittest" was a natural law, and that struggle led to improvement of the race. These ideas eventually fell from favour. His gastraea theory, tracing all multicellular animals to a hypothetical two-layered ancestor, stimulated both discussion and investigation. Darwin had described evolution through the natural selection of accumulated favourable variations that in time formed new species; to Haeckel, however, this was only a beginning, with consequences to be pursued further. Haeckel's publisher turned down a proposal for a "strictly scholarly and objective" second edition. Initially Haeckel trained as a physician, and then studied comparative anatomy with … Richardson & Keuck 2001. [5] Haeckel promoted and popularised Charles Darwin's work in Germany[6] and developed the influential but no longer widely held recapitulation theory ("ontogeny recapitulates phylogeny") claiming that an individual organism's biological development, or ontogeny, parallels and summarises its species' evolutionary development, or phylogeny. He had long been thinking of “vital molecular movement” when, in 1876, he attempted to place heredity on a molecular basis in a work entitled Die Perigenesis der Plastidule (“The Generation of Waves in the Small Vital Particles”). [55], Haeckel was awarded the title of Excellency by Kaiser Wilhelm II in 1907[56] and the Linnean Society of London's prestigious Darwin-Wallace Medal in 1908. [84] Gunther Hecht, a member of the Nazi Department of Race Politics, also issued a memorandum rejecting Haeckel as a forerunner of Nazism. [86], German biologist, philosopher, physician, and artist, "Haeckel" redirects here. Robert J. Richards, "Myth 19: That Darwin and Haeckel Were Complicit in Nazi Biology", in. [39], However, Robert J. Richards notes: "Haeckel, on his travels to Ceylon and Indonesia, often formed closer and more intimate relations with natives, even members of the untouchable classes, than with the European colonials." He was first to postulate a “missing link” between ape and man and was proven correct when Java man was found in 1891. [23], However, Haeckel's books were banned by the Nazi Party, which refused Monism and Haeckel's freedom of thought. [85] Kurt Hildebrandt, a Nazi political philosopher, also rejected Haeckel. He even formally named this missing link Pithecanthropus alalus, translated as "ape man without speech". Born in Germany in 1834, Ernst Haeckel studied medicine at the University of Berlin and graduated in 1857. In 1862 he was appointed extraordinary (that is, associate) professor of zoology, and that year, when he published his monograph on the Radiolaria, he expressed in it his agreement with Darwin’s theory of evolution; from that time he was a proponent of Darwinism, and he soon was lecturing to scientific and lay audiences on the descent theory. Ernst Haeckel, in full Ernst Heinrich Philipp August Haeckel, (born Feb. 16, 1834, Potsdam, Prussia [Germany]—died Aug. 9, 1919, Jena, Ger. [60], Darwin's 1859 book On the Origin of Species had immense popular influence, but although its sales exceeded its publisher's hopes it was a technical book rather than a work of popular science: long, difficult and with few illustrations. It was later said that "there is evidence of sleight of hand" on both sides of the feud between Haeckel and Wilhelm His. His propensities to systematization along evolutionary lines led to his valuable contributions to the knowledge of such invertebrates as medusae, radiolarians, siphonophores, and calcareous sponges. [66][67][68], The evidence is in some respects ambiguous. Ernst Heinrich Philipp August Haeckel (February 16, 1834 – 1919) was a philosopher, professor, physician, naturalist, biologist and artist. 7, showing His's drawing of the forelimb of a deer embryo developing a clef, compared with a similar drawing (Sakurai, 1906) showing the forelimb initially developing as a digital plate with rays. [20], Haeckel became the most famous proponent of Monism in Germany. Building collections around his own, Haeckel founded both the Phyletic Museum in Jena and the Ernst Haeckel Haus; the latter contains his books and archives, and it preserves many other mementos of his life and work. 495–528) show that it is a simplification to suppose that Haeckel held the recapitulation theory in its strong form. In 1906 Haeckel founded a group called the Monist League (Deutscher Monistenbund) to promote his religious and political beliefs. [citation needed], He was one of the first to consider psychology as a branch of physiology. As a philosopher, Ernst Haeckel wrote Die Welträthsel (1895–1899; in English: The Riddle of the Universe, 1901), the genesis for the term "world riddle" (Welträtsel); and Freedom in Science and Teaching[7] to support teaching evolution. He is regarded as a pioneer of eugenics and Nazi eugenics in Germany. Please select which sections you would like to print: Corrections? This species alone (with the exception of the Mongolian) has had an actual history; it alone has attained to that degree of civilisation which seems to raise men above the rest of nature. [13] During a trip to the Mediterranean, Haeckel named nearly 150 new species of radiolarians. From Ernst Haeckel's. [12], Ernst Haeckel studied under Karl Gegenbaur at the University of Jena for three years, earning a habilitation in comparative anatomy in 1861, before becoming a professor of zoology at Jena, where he remained for 47 years, from 1862 to 1909. As Blackwell (Am Biol Teach 69:135-136, 2007) pointed out, multiple authors have attempted to discredit Haeckel, stating that modern embryological studies have shown that Haeckel's drawings are stylized or embellished. If one views the origin of the branches of language as the special and principal act of becoming human, and the species of humankind as distinguished according to their language stem, then one can say that the different species of men arose independently of one another. In 1857 … [79][80] They also point to incompatibilities between evolutionary biology and Nazi ideology. These separate languages had completed the transition from animals to man, and under the influence of each main branch of languages, humans had evolved – in a kind of Lamarckian use-inheritance – as separate species, which could be subdivided into races. [14] Meanwhile, he completed a dissertation in zoology in 1861 at Jena and became privatdozent there. He held that evolutionary biology had definitively proven that races were unequal in intelligence and ability, and that their lives were also of unequal value. Ernst Mayr. In those days of great interest in protoplasm, it was believed for a while that certain deep-sea dredgings had brought up such structureless organisms; when scientists found this to be in error, Haeckel continued to insist, throughout the years, that “monera” existed. [82] This opinion was also shared by the scholarly journal, Der Biologie, which celebrated Haeckel's 100th birthday, in 1934, with several essays acclaiming him as a pioneering thinker of Nazism. His concept of recapitulation has been refuted in the form he gave it (now called "strong recapitulation"), in favour of the ideas first advanced by Karl Ernst von Baer. He declared that ontogeny (the embryology and development of the individual) briefly, and sometimes necessarily incompletely, recapitulated, or repeated, phylogeny (the developmental history of the species or race). Photograph of Ernst Haeckel (left) in the Canary Islands with his assistant Miklucho-Maclay in 1867. Haeckel's view can be seen as a forerunner of the views of Carleton Coon, who also believed that human races evolved independently and in parallel with each other. Thus they do not inform the debate and may themselves be disingenuous." Ernst Haeckel studied animals and evolution in Germany from 1834 to 1919. Though his concepts of recapitulation were in error, Haeckel brought attention to important biological questions. Ring in the new year with a Britannica Membership - Now 30% off. The German scientist’s lush drawings, watercolors, and sketches of lifeforms “from the highest mountaintops to the deepest ocean” were published in 59 scientific illustrations between 1860 and 1862. [18][19], Haeckel's wife, Agnes, died in 1915, and he became substantially frailer, breaking his leg and arm. Michael K. Richardson. Despite the significance to ideas of transformism, this was not really polite enough for the new popular science writing, and was a matter for medical institutions and for experts who could make their own comparisons. There were various styles of embryological drawings at that time, ranging from more schematic representations to "naturalistic" illustrations of specific specimens. When Haeckel was a student in the 1850s he showed great interest in embryology, attending the rather unpopular lectures twice and in his notes sketched the visual aids: textbooks had few illustrations, and large format plates were used to show students how to see the tiny forms under a reflecting microscope, with the translucent tissues seen against a black background. [citation needed], One student did find some remains: a Dutchman named Eugène Dubois searched the East Indies from 1887 to 1895, discovering the remains of Java Man in 1891, consisting of a skullcap, thighbone, and a few teeth. G. Fischer, Jena, Germany [in German] BHL Reference page. [12] In 1869 he traveled as a researcher to Norway, in 1871 to Croatia (where he lived on the island of Hvar in a monastery),[17] and in 1873 to Egypt, Turkey, and Greece. More importantly, though, "[37], In his introduction to the Nazi party ideologue Alfred Rosenberg's 1930 book, The Myth of the Twentieth Century, Peter Peel affirms that Rosenberg had indeed read Haeckel. Some scientists of the day suggested[30] Dubois' Java Man as a potential intermediate form between modern humans and the common ancestor we share with the other great apes. Before macro photography showed us tiny things in great detail, Ernst Heinrich Haeckel (16 February 1834 – 9 August 1919) drew life seen through his microscope. Haeckel introduced the concept of heterochrony, the change in timing of embryonic development over the course of evolution. Ernst Heinrich Philipp August Haeckel (1834–1919) wanted to be a botanist—his favorite book as a teenager was Mathias Schleiden’s Die Pflanzen und ihr Leben (1848), and his hero was Humboldt (Uschmann 1972, Krausse 1987, Hopwood 2000, Di Gregorio 2005, Richards 2008). 1998. Haeckel believed privately that his figures were both exact and synthetic, and in public asserted that they were schematic like most figures used in teaching. Ernst Haeckel, in full Ernst Heinrich Philipp August Haeckel, (born Feb. 16, 1834, Potsdam, Prussia [Germany]—died Aug. 9, 1919, Jena, Ger. [26] It proposed a link between ontogeny (development of form) and phylogeny (evolutionary descent), summed up by Haeckel in the phrase "ontogeny recapitulates phylogeny". The evolutionary study of embryos reached a peak in the late 1800s thanks primarily to the efforts of one extraordinarily gifted, though not entirely honest, scientist named Ernst Haeckel (left). Ernst Haeckel’s art became very popular as it paired colorful lithographs with information about these scientific marvels of nature. He then studied medicine in Berlin and Würzburg, particularly with Albert von Kölliker, Franz Leydig, Rudolf Virchow (with whom he later worked briefly as assistant), and with the anatomist-physiologist Johannes Peter Müller (1801–1858). We welcome any additional information. 215 ff. Moreover, it is worth mentioning that Haeckel had often overtly recognized the great contribution of educated Jews to the German culture. [citation needed], Haeckel argued that human evolution consisted of precisely 22 phases, the 21st – the "missing link" – being a halfway step between apes and humans. He was so precise Ernst Heinrich Philipp August Haeckel (16 February 1834 – 9 August 1919) was an influential German zoologist, naturalist, and artist. Ernst Haeckel's contribution to Evo-Devo and scientific debate: a re-evaluation of Haeckel's controversial illustrations in US textbooks in response to creationist accusations. Haeckel divided human beings into ten races, of which the Caucasian was the highest and the primitives were doomed to extinction. Ernst Haeckel was a German zoologist, evolutionist, philosopher, professor, naturalist, physician, biologist, and artist. One of the first problems with the illustrations in the first row of Haeckel’s comparative embryo plates in his work Anthropogenie is that he drew many embryos, including the human and chick embryos, without either pericardial or heart bulges, where they possess these in reality. [46]:264–267[47], Darwin's On the Origin of Species, which made a powerful impression on Haeckel when he read it in 1864, was very cautious about the possibility of ever reconstructing the history of life, but did include a section reinterpreting von Baer's embryology and revolutionising the field of study, concluding that "Embryology rises greatly in interest, when we thus look at the embryo as a picture, more or less obscured, of the common parent-form of each great class of animals." He also proposed the kingdom Protista[12] in 1866. The similarity of early vertebrate embryos became common knowledge, and the illustrations were praised by experts such as Michael Foster of the University of Cambridge. [16] In 1867 he married Agnes Huschke. [9][10], Ernst Haeckel was born on 16 February 1834, in Potsdam (then part of the Kingdom of Prussia). [76], On the other hand, Haeckel was not an anti-Semite. To meet his publisher's need for a popular work he used a student's transcript of his lectures as the basis of his Natürliche Schöpfungsgeschichte of 1868, presenting a comprehensive presentation of evolution. [46]:275–276;282–286, The revised 1870 second edition of 1,500 copies attracted more attention, being quickly followed by further revised editions with larger print runs as the book became a prominent part of the optimistic, nationalist, anticlerical "culture of progress" in Otto von Bismarck's new German Empire. [54] Robert J. Richards, in a paper published in 2008, defends the case for Haeckel, shedding doubt against the fraud accusations based on the material used for comparison with what Haeckel could access at the time. Between 1859 and 1866 Haeckel worked on many phyla, such as radiolarians, poriferans (sponges) and annelids (segmented worms). (Ironically, a new human species, Homo floresiensis, a dwarf human type, has recently been discovered in the island of Flores). The Caucasian, or Mediterranean man (Homo Mediterraneus), has from time immemorial been placed at the head of all the races of men, as the most highly developed and perfect. He was an atheist. The two massive volumes sold poorly, and were heavy going: with his limited understanding of German, Darwin found them impossible to read. It is generally called the Caucasian race, but as, among all the varieties of the species, the Caucasian branch is the least important, we prefer the much more suitable appellation proposed by Friedrich Müller, namely, that of Mediterranese.

Ernst Haeckel’s most popular book is Art Forms in Nature. Ernst Heinrich Philipp August Haeckel (German: [ˈʔɛɐ̯nst ˈhɛkl̩]; 16 February 1834 – 9 August 1919[1]) was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist, and artist who discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms, and coined many terms in biology, including ecology,[2] phylum,[3] phylogeny,[4] and Protista. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Ernst Mayr is arguably the most influential evolutionary biologist within the last … Ernst Haeckel (1834-1919) was the German scientist who coined the phrase “ontogeny recapitulates phylogeny” and the terms “Darwinism” and “ecology.”. But in a great majority of animals, including man, this is not possible because the infinitely varied conditions of existence have led the embryonic forms themselves to be changed and to partly lose their original condition (Haeckel, 1903: pp. SS captain and biologist Heinz Brücher wrote a biography of Haeckel in 1936, in which he praised Haeckel as a "pioneer in biological state thinking". He used morphology to reconstruct the evolutionary history of life, in the absence of fossil evidence using embryology as evidence of ancestral relationships. It mentioned von Baer's 1828 anecdote (misattributing it to Louis Agassiz) that at an early stage embryos were so similar that it could be impossible to tell whether an unlabelled specimen was of a mammal, a bird, or of a reptile, and Darwin's own research using embryonic stages of barnacles to show that they are crustaceans, while cautioning against the idea that one organism or embryonic stage is "higher" or "lower", or more or less evolved. Let us know if you have suggestions to improve this article (requires login). Haeckel's work focused often on the genesis and evolution of life and on the embryology of humans. [35] In his view, 'Negroes' were savages and Whites were the most civilised: for instance, he claimed that '[t]he Negro' had stronger and more freely movable toes than any other race, which, he argued, was evidence of their being less evolved, and which led him to compare them to '"four-handed" Apes'. In 1865 he was appointed full professor, and he remained at Jena until his retirement in 1909. As a book for the general public, it followed the common practice of not citing sources. On 21 October he visited Charles Darwin at Down House in Kent. [12] Together with Hermann Steudner he attended botany lectures in Würzburg. Dubois classified Java Man with Haeckel's Pithecanthropus label, though they were later reclassified as Homo erectus. In humans, the cardiovascular system is one of the first entities to develop in the early embryo. [69] As a result of the "struggle for existence", it followed that the "lower" races would eventually be exterminated. With each of these human species, language developed on its own and independently of the others. pt. He proposed the biogenetic law while working at the University of Jena in Jena, Germany, in his 1866 book Generelle Morphologie der Organismen [ General Morphology of the Organisms ]. On 17 October 1866 he arrived in London. some Anthozoa and Vermes) where we are authorised to interpret each embryological form directly as the historical representation or portrait-like silhouette of an extinct ancestral form. [40], Haeckel claimed the origin of humanity was to be found in Asia: he believed that Hindustan (Indian subcontinent) was the actual location where the first humans had evolved. An ardent Darwinist, Haeckel made several zoological expeditions and founded the Phyletic Museum at Jena and the Ernst Haeckel Haus, which contains his books, records, and other effects. [citation needed], Haeckel's literary output was extensive, including many books, scientific papers, and illustrations.[61]. The first published concerns came from Ludwig Rütimeyer, a professor of zoology and comparative anatomy at the University of Basel who had placed fossil mammals in an evolutionary lineage early in the 1860s and had been sent a complimentary copy. Watts E, Levit GS, Hossfeld U (2019). [31], The creationist polygenism of Samuel George Morton and Louis Agassiz, which presented human races as separately created species, was rejected by Charles Darwin, who argued for the monogenesis of the human species and the African origin of modern humans. Though he made no suggestion that embryo illustrations should be directly based on specimens, to him the subject demanded the utmost "scrupulosity and conscientiousness" and an artist must "not arbitrarily model or generalise his originals for speculative purposes" which he considered proved by comparison with works by other authors. [51] Recent analyses (Richardson 1998, Richardson and Keuck 2002) have found that some of the criticisms of Haeckel's embryo drawings were legitimate, but others were unfounded.
