Ernst Haeckel's Anthropogenie, oder, Entwickelungsgeschichte des menschen, a simplified embryology textbook focusing on ontogeny and phylogeny, was first published in 1874. Challenged on the accuracy of its embryological illustrations and it's promotion of the recently developed theories of Darwin, the book's publication was the subject of much controversy. Many of the work's embryological illustrations were borrowed from previous textbooks, along with a few originals by Haeckel himself.
