Unlike his many popular books of essays, it was a technical book, and over the following decades it was influential in stimulating research into heterochrony (changes in the timing of embryonic development), which had been neglected since Ernst Haeckel's theory that ontogeny recapitulates phylogeny [a] had been largely discredited.
1858, elaboration of evolutionary theory, Darwin and Wallace, [30] also in Origin of Species by Darwin the following year, precursor concept. 1866, Ernst Haeckel, first publishes his phylogeny-based evolutionary tree, precursor concept. Haeckel introduces the now-disproved recapitulation theory.
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 .
