Versuch die Metamorphose der Pflanzen zu erklären, known in English as Metamorphosis of Plants, was published by German poet and philosopher Johann Wolfgang von Goethe in 1790.[1] In this work, Goethe essentially discovered the (serially) homologous nature of leaf organs in plants, from cotyledons, to photosynthetic leaves, to the petals of a flower. Although Sir Richard Owen, the British vertebrate anatomist, is generally credited with first articulating a definition of the word "homology" (in 1843), it is clear that Goethe had already arrived at a sophisticated view of homology and transformation (within an idealist morphological perspective) more than fifty years earlier.
