Haeckel, ErnstHeinrichPhilippAugust

Haeckel, ErnstHeinrichPhilippAugust (1834–1919)A German anatomist, zoologist, and field naturalist, who was appointed professor of zoology at the Zoological Institute, Jena, in 1865. He was an enthusiastic supporter of the Darwinian theory of evolution and Darwin credited him with the success that theory enjoyed in Germany. Haeckel constructed genealogical trees for many living organisms and divided animals into Protozoa (single-celled) and Metazoa (multi-celled) groups. He was an accomplished field naturalist and is usually credited with having coined the word ‘ecology’ in his Generelle Morphologie der Organismen, published in two volumes in 1866 (as the German word ökologie, from the Greek oikos, meaning ‘house’ and logos, meaning ‘discourse’).

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
