Illustration in Ernst Haeckel's 'Anthropogenie oder, Entwickelungsgeschichte des Menschen' ('Anthropogenie or The Evolution of Man', a history of human development) published by Verlag von Wilhelm Engelmann, 1874. A still controversial treatise on human and evolutionary embryology which propounded that 'phylogeny recapitulates ontology.' The book has been seen as pushing the facts and pictures to fit the theories, and has been seen by many to have done more harm than good towards advancing evolutionary theories. Haeckel (1834-1919) was a German biologist, naturalist, and artist who discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms, and coined many terms in biology, including anthropogeny, ecology, phylum, phylogeny, stem cell, and Protista. |
