![“Phylogeny and ontogeny are, therefore, the two coordinated branches of morphology. Phylogeny is the developmental history [Entwickelungsgeschichte] of the abstract, genealogical individual; ontogeny, on the other hand, is the developmental history of the concrete, morphological individual.” quote by Ernst Haeckel](https://sms4smile.com/quotes/img-quotes/bfa/ernst-haeckel-20972_abstract_phylogeny-and-ontogeny-are-therefore-the_1640087.jpg)
