Although Haeckel's ideas are important to the history of evolutionary theory, and although he was a competent invertebrate anatomist most famous for his work on radiolaria, many speculative concepts that he championed are now considered incorrect.
His best-known compositions include 9 symphonies, 5 concertos for piano, 32 piano sonatas, and 16 string quartets. He also composed other chamber music, choral works (including the celebrated Missa Solemnis), and songs. [12] [13] [14] He has been labeled a deist as well. [15] Caspar David Friedrich (1774–1840), German Romantic landscape ...
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.
The theory of recapitulation, also called the biogenetic law or embryological parallelism—often expressed using Ernst Haeckel's phrase "ontogeny recapitulates phylogeny"—is a 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 ...
Proteus is an animated documentary film written and directed by David Lebrun in 2004. [1] It depicts a 19th-century understanding of the sea by interweaving the life and work of German biologist and researcher Ernst Haeckel with excerpts from Samuel Taylor Coleridge's epic poem The Rime of the Ancient Mariner, and the story of the oceanographic Challenger expedition of the 1870s.
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 ...
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.
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 ...
