As an artist known for stylised paintings of nature's diversity, Ernst Haeckel (1834-1919) is still much admired.
Gliboff not only breaks new ground in our historical and theoretical understanding of Ernst Haeckel's role in the German assimilation of Darwin (Haeckel's work hugely outsold his intellectual master's), but he also examines the work of Germany's preeminent paleontologist Heinrich Georg Bronn, the person through whom Darwin's The Origin of Species first reached its German-speaking readership.
Furthermore, the footnotes to this work affirmed Darwin's favorable attitude to the writings of well-known radical German materialists such as Karl Vogt (1817-95) and Ludwig Buchner (1824-99), and he cited with approval the "excellent discussions on the steps by which man became a biped" in one of the most anti-religious of all of Ernst Haeckel's works, the Natural History of Creation (Naturliche Schopfungsgeschichte) of 1868 (English ed., 1876).
In 1866 Ernst Haeckel advanced the classification game by grouping microorganisms into their own kingdom, Protista.
In his book, The Scientific Origins of National Socialism, Daniel Gasman posits that it was 19th century German scientific biology generally and the biophilosophy of Ernst Haeckel specifically laid the ideological groundwork of the Third Reich and the radical policies of Nazi biopolitics.
In 1866 the German zoologist and social Darwinist Ernst Haeckel published his book Generelle Morphologie in which the word 'ecology' was first coined.
Darwin said that "by far the strongest class of facts" that proved his theory came from embryology--in particular relying on German biologist Ernst Haeckel. Haeckel made drawings of classes of vertebrates, showing them to be very much alike in their initial stages of formation, allowing Darwin to point to them as "proof" that all animals have the same origin.
The second reconstructs the development of Ernst Haeckel's interpretation of biological evolution and shows how Haeckel, for all his insistent materialism, participates in the discourse of the 'soul' at work in natural phenomena, which can perhaps be seen as further evidence of Fechner's influence.
Here the author connects with his previous books (Darwin and the Emergence of Evolutionary Theories of Mind and Behavior, 1987; The Meaning of Evolution, 1992), but he also signals the way to further research into the origins in the Romantic movement of nineteenth-century biology, and Ernst Haeckel in particular.
