Ernst Heinrich Philipp August Haeckel (German: [ɛʁnst ˈhɛkl̩]; 16 February 1834 – 9 August 1919) [ 1 ] was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist. He discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms and coined ...
The theory of recapitulation, also called the biogenetic law or embryological parallelism—often expressed using Ernst Haeckel's phrase "ontogeny recapitulates phylogeny"—is an historical hypothesis that the development of the embryo of an animal, from fertilization to gestation or hatching (), goes through stages resembling or representing successive adult stages in the evolution of the ...
Kunstformen der Natur was influential in early 20th-century art, architecture, and design, bridging the gap between science and art. In particular, many artists associated with Art Nouveau were influenced by Haeckel's images, including René Binet, Karl Blossfeldt, Hans Christiansen, and Émile Gallé. One prominent example is the Amsterdam ...
Because it shows relationships (phylogeny) and time (generations), it is a timetree. In contrast, Ernst Haeckel illustrated a phylogenetic tree (branching only) in 1866, not scaled to time, and of real species and higher taxa. In his summary to the section, Darwin put his concept in terms of the metaphor of the tree of life:
Ernst Haeckel wrote about the World Riddle in 1895.. The term "world riddle" or "world-riddle" has been associated, for over 100 years, with Friedrich Nietzsche (who mentioned Welträthsel in several of his writings) and with the biologist-philosopher Ernst Haeckel, who, as a professor of zoology at the University of Jena, wrote the book Die Welträthsel in 1895–1899, in modern spelling Die ...
von Baer's laws (embryology) Embryology theories of Ernst Haeckel (following Meckel) and Karl Ernst von Baer compared. Von Baer denied any recapitulation of whole adult forms, though individual structures might be recapitulated. In developmental biology, von Baer's laws of embryology (or laws of development) are four rules proposed by Karl ...
The term "ecology" (German: Oekologie, Ökologie) was coined by Ernst Haeckel in his book Generelle Morphologie der Organismen (1866). [240] Haeckel was a zoologist, artist, writer, and later in life a professor of comparative anatomy. [229] [241] Opinions differ on who was the founder of modern ecological theory.
Ernst Haeckel was a German biologist, zoologist, and artist of the late 19th and early 20th centuries who used art to illustrate his scientific findings before macrophotography and photographic microscopy. He meticulously recorded the hidden intricacies of natural forms through his vibrant and stylized drawings.
