The word " ecology " (" Ökologie ") was coined in 1866 by the German scientist Ernst Haeckel ( 1834 – 1919 ).

The term " ecology " () is of a more recent origin and was first coined by the German biologist Ernst Haeckel in his book Generelle Morphologie der Organismen ( 1866 ).

also written von Haeckel, was an eminent German biologist, naturalist, philosopher, physician, professor 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 anthropogeny, ecology, phylum, phylogeny, stem cell, and the kingdom Protista.

Ernst Haeckel was born on February 16, 1834, in Potsdam ( then part of Prussia ).

Haeckel was the first person known to use the term " First World War ".

Haeckel was a zoologist, an accomplished artist and illustrator, and later a professor of comparative anatomy.

Haeckel was a flamboyant figure.

On the other hand, Michael K. Richardson, Professor of Evolutionary Developmental Zoology, Leiden University, while recognizing that some criticisms of the drawings are legitimate ( indeed, it was he and his co-workers who began the modern criticisms in 1998 ), has supported the drawings as teaching aids, and has said that " on a fundamental level, Haeckel was correct "

Haeckel was not the only one to create a series of drawings representing embryonic development.

Wilhelm His was one of Haeckel ’ s most authoritative and primary opponents advocating physiological embryology.

The first suggestion of fakery against Haeckel was made in late 1868 by Ludwig Rutimeyer in the Archiv fur Anthropogenie.

As a pioneer in mammalian embryology, he was one of Haeckel ’ s strongest critics.

Nevertheless, Bischoff ’ s main argument was in reference to Haeckel ’ s drawings of human embryos, for Haeckel is later accused of miscopying the dog embryo from him.

Throughout Haeckel ’ s time, criticism of his embryo drawings was often due in part to his critics ' belief in his representations of embryological development as “ crude schemata .” In this way, Haeckel specifically selected relevant features to portray in his drawings.

Ernst Haeckel was particularly ardent, aiming to synthesise Darwin's ideas with those of Lamarck and Goethe while still reflecting the spirit of Naturphilosophie.

The concept of a biotope was first advocated by Ernst Haeckel ( 1834-1919 ): a German zoologist famous for the recapitulation theory.

On the other hand, it does seem likely that Marr was influenced by Ernst Haeckel, a professor who popularized the notion of Social Darwinism among Germany's educated classes.

Indeed, it was the question of where to put such " unclassifiable " creatures that prompted Ernst Haeckel to add a third kingdom to the Animale and Vegetabile of Linnaeus: the Kingdom Protista.

The term nekton was coined in 1890 by Ernst Haeckel ; it is rooted in the Greek adjective νηκτός nēktós (" the swimming ") derived from the verb νήχειν nḗkhein (" to swim ").

Amniota was first formally described by embryologist Ernst Haeckel in 1866 on the presence of the amnion, hence the name.

Nevertheless, his chief interest was in human evolution, influenced by Ernst Haeckel, who reasoned that there must be intermediate species between apes and human.

Friedrich Ratzel ( 1844 – 1904 ), influenced by thinkers like Darwin and zoologist Ernst Heinrich Haeckel, contributed to Geopolitik by the expansion on the biological conception of geography, without a static conception of borders.

Influenced by thinkers like Darwin and zoologist Ernst Heinrich Haeckel, he published several papers.

Darwin was visited in October 1866 by the zoologist Ernst Haeckel, who over the years had built support for Darwin in Germany, now getting huge classes at Jena for his lectures on Darwinismus.

The later fame of Ernst Haeckel eclipsed Darwin in some European countries, as the term " Haeckelism " was more common than Darwinism.

Haeckel later abandoned this idea which is revived by Hadzi in 1953.

In response to Haeckel ’ s evolutionary claim that all vertebrates are essentially identical in the first month of embryonic life as proof of common descent, His responds by insisting that a more skilled observer would recognize even sooner that early embryos can be distinguished.

In 1866, following earlier proposals by Richard Owen and John Hogg, Ernst Haeckel proposed a third kingdom of life.

Ernst Haeckel ( 1834 – 1919 ) became famous for his " recapitulation theory ", according to which each individual mirrors the evolution of the whole species during his life.

* Ernst Haeckel challenges the plant / animal division of life, observing that single celled organisms, the protists, do not fit into either category.

Early twentieth-century biologists like Ernst Haeckel viewed embryology as a recapitulation of evolution, which implies a kind of organising memory, and a few modern biologists, such as Rupert Sheldrake, influenced by Jungian ideas and by vitalism, have posited organising fields of life consisting of memories and drives.

The complete phrase " argument from poor design " has rarely been used in the literature, but arguments of this type have appeared many times, sometimes referring to poor design, in other cases to suboptimal design, unintelligent design, or dysteleology ; the last is a term applied by the nineteenth-century biologist Ernst Haeckel to the implications of organs so rudimentary as to be useless to the life of an organism (, p. 331 ).

In what was to be the last decade of his life, he penned works such as Parsifal Unveiled, which details the esoteric symbolism of the Wagner opera, and Gnostic Anthropology in which he heavily criticizes the theories of Darwin, Haeckel, " and their followers ".

During these times, he worked several times at facilities located by the sea: Heligoland alongside Haeckel in 1865, Hamburg in 1866, Millport, Scotland with David Robertson in 1867 and 1868 and moved to Messina, Italy, during the winter of 1868 together with his friend and colleague Nicholas Miklouho-Maclay to work on the marine life of the Straits of Messina.

Haeckel studied under Karl Gegenbaur at the University of Jena for three years, earning a doctorate in zoology, before becoming a professor of comparative anatomy at the University of Jena, where he remained for 47 years, from 1862 to 1909.

As a professor of anatomy at the University of Jena ( 1855 – 1873 ) and at the University of Heidelberg ( 1873 – 1903 ), Carl Gegenbaur was a strong supporter of Charles Darwin's theory of organic evolution, having taught and worked, beginning in 1858, with Ernst Haeckel, 8 years his junior.

In 1855, he was appointed extraordinary professor of anatomy at the University of Jena, and in 1858, he became the ordinary professor, where after 1865, his former student and fellow-worker Ernst Haeckel was professor of zoology.

In 1858, the physician Ernst Haeckel studied under Carl Gegenbaur at Jena, receiving a doctorate in zoology ( after his medical degree ), and became a professor at the same institution, the University of Jena ( see: Ernst Haeckel ).
