By the time Haeckel was teaching he was able to use a textbook with woodcut illustrations written by his own teacher Albert von Kölliker, which purported to explain human development while also using other mammalian embryos to claim a coherent sequence. At the end of 1868 his review in the Archiv für Anthropologie wondered about the claim that the work was "popular and scholarly", doubting whether the second was true, and expressed horror about such public discussion of man's place in nature with illustrations such as the evolutionary trees being shown to non-experts. This article is a contribution to the Special Issue Ernst Haeckel (1834–1919): The German Darwin and his impact on modern biology—Guest Editors: U. Hossfeld, G. S. Levit, U. Kutschera. He used morphology to reconstruct the evolutionary history of life, in the absence of fossil evidence using embryology as evidence of ancestral relationships.

He became a key figure in social darwinism and leading proponent of scientific racism, stating for instance:.  As an advocate of eugenics, he also believed that about 200,000 mentally and congenitally ill should be killed by a medical control board. 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.  ), German zoologist and evolutionist who was a strong proponent of Darwinism and who proposed new notions of the evolutionary descent of human beings. Enthusiastically attempting to explain both inorganic and organic nature under the same physical laws, Haeckel portrayed the lowest creatures as mere protoplasm without nuclei; he speculated that they had arisen spontaneously through combinations of carbon, oxygen, nitrogen, hydrogen, and sulfur. 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. Between 1859 and 1866 Haeckel worked on many phyla, such as radiolarians, poriferans (sponges) and annelids (segmented worms). "While some criticisms of the drawings are legitimate, others are more tendentious", Richardson and Keuck "Haeckel's ABC of evolution and development". Duplication using galvanoplastic stereotypes (clichés) was a common technique in textbooks, but not on the same page to represent different eggs or embryos. Haeckel saw evolution as the basis for a unified explanation of all nature and the rationale of a philosophical approach that denied final causes and the teleology of the church. , Haeckel's literary output was extensive, including many books, scientific papers, and illustrations..  Others have denied the relationship all together. Ernst Heinrich Philipp August Haeckel (16 February 1834 – 9 August 1919) was an influential German zoologist, naturalist, and artist. 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's embryos continued". 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. At that time, no remains of human ancestors had yet been identified. The first chapter included an illustration: "As some of my readers may never have seen a drawing of an embryo, I have given one of man and another of a dog, at about the same early stage of development, carefully copied from two works of undoubted accuracy" with a footnote citing the sources and noting that "Häckel has also given analogous drawings in his Schöpfungsgeschichte." The turning point in Haeckel’s thinking was his reading of Charles Darwin’s 1859 work, On the Origin of Species by Means of Natural Selection. Ernst Haeckel’s most popular book is Art Forms in Nature. He was also a philosopher and physician, but in those fields he is not regarded as particularly notable. Ring in the new year with a Britannica Membership - Now 30% off. Initially Haeckel trained as a physician, and then studied comparative anatomy with … Ernst Mayr is arguably the most influential evolutionary biologist within the last … , 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." In 1891 Haeckel made the excuse that this "extremely rash foolishness" had occurred in undue haste but was "bona fide", and since repetition of incidental details was obvious on close inspection, it is unlikely to have been intentional deception. , In his Ontogeny and Phylogeny Harvard paleontologist Stephen Jay Gould wrote: "[Haeckel's] evolutionary racism; his call to the German people for racial purity and unflinching devotion to a 'just' state; his belief that harsh, inexorable laws of evolution ruled human civilization and nature alike, conferring upon favored races the right to dominate others ... all contributed to the rise of Nazism. At least this is the view of Schleicher, one of the foremost authorities on this subject.  Haeckel supported the theory with embryo drawings that have since been shown to be oversimplified and in part inaccurate, and the theory is now considered an oversimplification of quite complicated relationships, however comparison of embryos remains a powerful way to demonstrate that all animals are related. Relating different images on a grid conveyed a powerful evolutionary message. , 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. It was later said that "there is evidence of sleight of hand" on both sides of the feud between Haeckel and Wilhelm His. 1: 1–363. 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. , 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. 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. He accused Haeckel of "playing fast and loose with the public and with science", and failing to live up to the obligation to the truth of every serious researcher. ), German zoologist and evolutionist who was a strong proponent of Darwinism and who proposed new notions of the evolutionary descent of human beings. Ernst Haeckel studied animals and evolution in Germany from 1834 to 1919. 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. 215 ff. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. From Ernst Haeckel's.  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.  Ernst Haeckel’s Alleged Anti-Semitism and Contributions to Nazi Biology Robert J. Richards1 The University of Chicago Figure 1: Haeckel’s stem-tree of the nine human species, with their varieties; the ape-man at the source. , In the same line of thought, historian Daniel Gasman states that Haeckel's ideology stimulated the birth of Fascist ideology in Italy and France. , In 1864, his beloved first wife, Anna Sethe, died. Ernst Haeckel was a German biologist, naturalist, and artist who pioneered the practice of using artistic illustrations to capture the likenesses of animals in the wild during the 19th century. , 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. 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).  As Haeckel stated:. Ernst Heinrich Philipp August Haeckel (German: [ˈʔɛɐ̯nst ˈhɛkl̩]; 16 February 1834 – 9 August 1919) 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, phylum, phylogeny, and Protista. , Haeckel also applied the hypothesis of polygenism to the modern diversity of human groups. , Haeckel was a zoologist, an accomplished artist and illustrator, and later a professor of comparative anatomy. It was frequently reprinted until 1926. Developmental series were used to show stages within a species, but inconsistent views and stages made it even more difficult to compare different species. In 1852 Haeckel completed studies at the Domgymnasium, the cathedral high-school of Merseburg. , German biologist, philosopher, physician, and artist, "Haeckel" redirects here. Some scientists of the day suggested Dubois' Java Man as a potential intermediate form between modern humans and the common ancestor we share with the other great apes. 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”). Watts E, Levit GS, Hossfeld U (2019). The fifth edition of Haeckel's book appeared in 1874, with its frontispiece a heroic portrait of Haeckel himself, replacing the previous controversial image of the heads of apes and humans. The current consensus of anthropologists is that the direct ancestors of modern humans were African populations of Homo erectus (possibly Homo ergaster), rather than the Asian populations exemplified by Java Man and Peking Man. Haeckel argued that humans were closely related to the primates of Southeast Asia and rejected Darwin's hypothesis of Africa. … There is certainly, even now, a number of lower vertebrate animals (e.g. 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. This group lasted until 1933 and included such notable members as Wilhelm Ostwald, Georg von Arco (1869-1940), Helene Stöcker and Walter Arthur Berendsohn. 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. Ernst Haeckel was a German biologist of the late mid 1800s who made commentary on a large range of issues, ranging from philosophy to development … 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.  In 1869 he traveled as a researcher to Norway, in 1871 to Croatia (where he lived on the island of Hvar in a monastery), and in 1873 to Egypt, Turkey, and Greece. Haeckel took particular care over the illustrations, changing to the leading zoological publisher Wilhelm Engelmann of Leipzig and obtaining from them use of illustrations from their other textbooks as well as preparing his own drawings including a dramatic double page illustration showing "early", "somewhat later" and "still later" stages of 8 different vertebrates.  Alfred Ploetz, founder of the German Society for Racial Hygiene, praised Haeckel repeatedly, and invited him to become an honorary member. In humans, the cardiovascular system is one of the first entities to develop in the early embryo. He was first to postulate a “missing link” between ape and man and was proven correct when Java man was found in 1891.  There were multiple versions of the embryo drawings, and Haeckel rejected the claims of fraud. A staunch evolutionary biologist, Haeckel put Darwin on the world map. His gastraea theory, tracing all multicellular animals to a hypothetical two-layered ancestor, stimulated both discussion and investigation. As a book for the general public, it followed the common practice of not citing sources. Richardson and Keuck say "Unfortunately His's embryos are mostly at later stages than the nearly identical early stage embryos illustrated by Haeckel [top row of Haeckel's drawing]. Affiliations , Haeckel argued that human evolution consisted of precisely 22 phases, the 21st – the "missing link" – being a halfway step between apes and humans. 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. It was a bestselling, provocatively illustrated book in German, titled Natürliche Schöpfungsgeschichte, published in Berlin in 1868, and translated into English as The History of Creation in 1876. , On the other hand, Haeckel was not an anti-Semite. In Haeckel’s book The History of Creation (1884) he included migration routes which he thought the first humans had used outside of Lemuria. :264–267, 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."  During a trip to the Mediterranean, Haeckel named nearly 150 new species of radiolarians. , Nazis themselves divided on the question of whether Haeckel should be counted as a pioneer of their ideology.  Haeckel promoted and popularised Charles Darwin's work in Germany 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. Updates?  Other Nazis kept their distance from Haeckel. (Haeckel, 1866), vol.  Together with Hermann Steudner he attended botany lectures in Würzburg. He was known for his contributions in the scientific realm, including discovering and naming thousands of species, coining different biological terms, and mapping a genealogical tree.  Gunther Hecht, a member of the Nazi Department of Race Politics, also issued a memorandum rejecting Haeckel as a forerunner of Nazism. 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.

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. 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. Watts E (1), Levit GS (2), Hossfeld U (3).  This idea was later put into practice by the Third Reich, as part of the Aktion T4 program. Haeckel, E. 1879. From p. 215: CS1 maint: multiple names: authors list (. , 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. :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. From this, Haeckel drew the implication that languages with the most potential yield the human races with the most potential, led by the Semitic and Indo-Germanic groups, with Berber, Jewish, Greco-Roman and Germanic varieties to the fore. In the racial hierarchies he constructed Jews tended to appear closer to the top, rather than closer to the bottom as in Nazi racial thought. Such experiences in marine biology strongly attracted Haeckel toward zoology, but dutifully he took a medical degree, as his family wished, at Berlin in 1857. He was the first to divide the animal kingdom into unicellular and multicellular animals. Haeckel's notion that ontogeny recapitulates phylogeny was deeply flawed, but it was at least straightforward. Reynolds, Andrew // History of Science;Jun2008, Vol. Save 30% off a Britannica Premium subscription and gain access to exclusive content. 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 was a flamboyant figure, who sometimes took great, non-scientific leaps from available evidence.  Kurt Hildebrandt, a Nazi political philosopher, also rejected Haeckel. Richardson and Keuck, (Biol.  They also point to incompatibilities between evolutionary biology and Nazi ideology. 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". Here again he traced a branching scheme, this time to illustrate the mechanism of heredity and to show the influence of outer conditions on the inherited undulatory motion he attributed to the “plastidules,” the term he adopted for the molecules making up protoplasm. An effective popularizer of science, Haeckel produced numerous tree diagrams, showing evolutionary relationships between different species. Das System der Medusen. Ernst Haeckel – Evolution's controversial artist. Ernst Haeckel's evolutionary scheme presented in the form of a tree. , The evidence is in some respects ambiguous.  For example, Haeckel described and named hypothetical ancestral microorganisms that have never been found. Our editors will review what you’ve submitted and determine whether to revise the article. , However, Haeckel's books were banned by the Nazi Party, which refused Monism and Haeckel's freedom of thought. Ernst Haeckel, in full Ernst Heinrich Philipp August Haeckel, (born Feb. 16, 1834, Potsdam, Prussia [Germany]—died Aug. 9, 1919, Jena, Ger. In 1865 he was appointed full professor, and he remained at Jena until his retirement in 1909. Ernst Haeckel’s art became very popular as it paired colorful lithographs with information about these scientific marvels of nature.  The principal arguments of historians who deny a meaningful connection between Haeckel and Nazism are that Haeckel's ideas were very common at the time, that Nazis were much more strongly influenced by other thinkers, and that Haeckel is properly classified as a 19th century German liberal, rather than a forerunner to Nazism. , Haeckel's affinity for the German Romantic movement, coupled with his acceptance of a form of Lamarckism, influenced his political beliefs. Over the next few days he met Charles Lyell, and visited Thomas Huxley and family at their home. Vol. Ernst Haeckel, in full Ernst Heinrich Philipp August Haeckel, (born Feb. 16, 1834, Potsdam, Prussia [Germany]—died Aug. 9, 1919, Jena, Ger. 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.  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. The occupation of physician appeared less worthwhile to Haeckel after contact with suffering patients. Interestingly, though it was only on a theoretical basis, he suggested as early as 1866 that the cell nucleus was concerned with inheritance. Rather than being a strict Darwinian, Haeckel believed that the characteristics of an organism were acquired through interactions with the environment and that ontogeny reflected phylogeny. With each of these human species, language developed on its own and independently of the others. Please select which sections you would like to print: Corrections? , Haeckel later claimed that the missing link was to be found on the lost continent of Lemuria located in the Indian Ocean. 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. 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 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. Richardson & Keuck 2001. , Haeckel became the most famous proponent of Monism in Germany. 495–528) show that it is a simplification to suppose that Haeckel held the recapitulation theory in its strong form. Review (2002), 77, pp. 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 ]. Together with Hermann Steudner he attended botanylectures in Würzburg. 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. Haeckel tended to speculate, and for some years, he pondered the problem of heredity. 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. Haeckel grew up in Merseburg, where his father was a government official. 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. 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. Ernst Haeckel was born on 16 February 1834, in Potsdam (then part of the Kingdom of Prussia). 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". Moreover, it is worth mentioning that Haeckel had often overtly recognized the great contribution of educated Jews to the German culture. Nazi propaganda guidelines issued in 1935 listed books which popularized Darwin and evolution on an "expunged list". , Haeckel's wife, Agnes, died in 1915, and he became substantially frailer, breaking his leg and arm. Haeckel retired from teaching in 1909, and in 1910 he withdrew from the Evangelical Church of Prussia. 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. At Messina he studied the one-celled protozoan group Radiolaria, members of which are strikingly crystalline in form; not surprisingly, Haeckel later maintained that the simplest organic life had originated spontaneously from inorganic matter by a sort of crystallization. Ernst Mayr. and says the Nazis rejected Haeckel, since he opposed antisemitism, while supporting ideas they disliked (for instance atheism, feminism, internationalism, pacifism etc.). Some historians have seen Haeckel's social Darwinism as a forerunner to Nazi ideology. There were various styles of embryological drawings at that time, ranging from more schematic representations to "naturalistic" illustrations of specific specimens. 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. pt.  He was the first person to use the term "first world war".  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. 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.
