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 ...
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 ...
Romanes' 1892 copy of Ernst Haeckel's allegedly fraudulent embryo drawings (this version of the figure is often attributed incorrectly to Haeckel). [1]Haeckel's illustrations show vertebrate embryos at different stages of development, which exhibit embryonic resemblance as support for evolution, recapitulation as evidence of the Biogenetic Law, and phenotypic divergence as evidence of von Baer ...
Haeckel and other German scientists would take the lead in launching an ambitious programme to reconstruct the evolutionary history of life based on morphology and embryology. [ 100 ] Darwin's theory succeeded in profoundly altering scientific opinion regarding the development of life and in producing a small philosophical revolution. [ 101 ]
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.
Evolutionary progress as a tree of life. Ernst Haeckel, 1866 Lamarck's two-factor theory involves 1) a complexifying force that drives animal body plans towards higher levels (orthogenesis) creating a ladder of phyla, and 2) an adaptive force that causes animals with a given body plan to adapt to circumstances (use and disuse, inheritance of acquired characteristics), creating a diversity of ...
The Radiolaria, also called Radiozoa, are unicellular eukaryotes of diameter 0.1–0.2 mm that produce intricate mineral skeletons, typically with a central capsule dividing the cell into the inner and outer portions of endoplasm and ectoplasm. The elaborate mineral skeleton is usually made of silica. [1]
Haeckel's work (with some notable exceptions in embryology) is usually considered reasonably accurate. ernst Haeckel was a major 19th century biologist, though he's best known today for "ontogeny recapitulates phylogeny", a misguided notion.
