Darwin's 1859 book ''[[On the Origin of Species]]'' had immense popular influence, but although its sales exceeded its publisher's hopes it was a technical book rather than a work of popular science: long, difficult and with few illustrations. One of Haeckel's books did a great deal to explain his version of "[[Darwinism]]" to the world. It was a bestselling, provocatively illustrated book in German, titled ''Natürliche Schöpfungsgeschichte'', published in Berlin in 1868, and translated into English as ''The History of Creation'' in 1876. Until 1909, eleven editions had appeared, as well as 25 translations into other languages. The ''Natürliche Schöpfungsgeschichte'' cemented Haeckel's reputation as one of Germany's most forceful popularizers of science. His ''Welträthsel'' were reprinted ten times after the book's first publication in 1899; ultimately, over 400,000 copies were sold.<ref>{{harvnb|Daum|1998|pp=305–6}}</ref>

Haeckel argued that human evolution consisted of precisely 22 phases, the 21st – the "[[Transitional fossil|missing link]]" – being a halfway step between apes and humans. He even formally named this missing link ''Pithecanthropus alalus'', translated as "ape man without speech".<ref>{{cite journal |last1=Schmutz |first1=Hans-Konrad |title=Hypothetische Bindeglieder zwischen Affe und Mensch: Zur fossilarmen Frühgeschichte der Paläoanthropologie |journal=Sudhoffs Archiv  |date=1984 |volume=68 |issue=1 |pages=77–83 |jstor=20776898 |url=http://www.jstor.org/stable/20776898 |access-date=11 March 2021}}</ref>

Haeckel's literary output was extensive, including many books, scientific papers, and illustrations.<ref name="WorldCat">{{cite web|title=Ernst Haeckel|url=https://www.worldcat.org/search?qt=worldcat_org_bks&q=Ernst+Haeckel&fq=dt%3Abks#x0%253Abook-%2C%2528x0%253Abook%2Bx4%253Aprintbook%2529format|publisher=WorldCat|access-date=4 June 2017}}</ref>
