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.

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 ...
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.

The altered political situation is also apparent in the work of Ernst Haeckel, who embraced the concept of a scientific worldview from the materialists but gave it a fresh political orientation. Haeckel, who was 17 years younger than Vogt, established himself as a proponent of Darwinism in Germany during the 1860s.
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 ...
Ernst Heinrich Philipp August Haeckel (February 16, 1834 – August 9, 1919), also written von Haeckel, was an eminent German biologist and philosopher. He promoted Charles Darwin's work in Germany and developed the theory that the organism's biological development, or ontogeny , parallels its species' evolutionary development, or phylogeny .
As in many of Haeckel's prints, the colors and spatial composition are more of an aesthetic choice than a reproduction of nature; the lithographer Adolf Glitsch worked directly from Haeckel's sketches rather than from first-hand specimens.
