Goethe intermaxillary bone
Goethe's 1784 illustrations of the comparative morphology of an animal and a human, showing that they both possess an intermaxillary bone, and thus both must have morphed (Goethe's term) or evolved (Darwin's term) from a common original form. [4]
In science, morphology is the study of the “form, formation, and transformation of organisms”, as originally defined by German polymath Johann Goethe, a variant of which would later come to be known as the theory of "evolution" as popularized by English naturalist Charles Darwin. [5]

Morphology, said another way, is the study of form similarity, change, and development in animated species.

In 8AD, Roman poet Ovid, published his mythological hexameter poem Metamorphoses; some of which is found in Goethe’s “ECHO cypher” of his Elective Affinities.

In 1784, Goethe initiated the subject of comparative morphology when he discovered the human intermaxillary bone, a bone thought to be unique to lower animals only and not to be found in humans.

This year or thereabouts marks the point when Goethe began serious searching for a scientific principle that could explain the commonality of form change and development across all species of plants, animals, and humans.

In a handwritten note to his Morphology, Goethe defines the subject as follows: [1]

Form is a thing in motion, in the process of becoming, of passing away. The study of form is the study of transformation. The study of metamorphosis is the key to all the signs of nature.”

Between 1817 and 1824 Goethe published essays on morphology and general scientific topics in two series. [2]

In his Zur Morphologie (On Morphology), Goethe declared his preference for the idea of Trieb (drive) as representing the developmental dynamic of living nature, in contrast to Kraft (force), which indicated a material principle that could not explain organization. [3]

German physician-physicist Hermann Helmholtz, in his essay “On Goethe’s Scientific Researches” (1853), surmised that Goethe’s studies of comparative botany and comparative anatomy led him to “a happy glimpse of an all-pervading law” of the conception that the differences in the anatomy different animals or morphology of different plants are to be “looked upon as variations from a common phase or type, induced by differences of habit, locality, or food.”

American comparative literature scholar Stefani Engelstein (2008), argues that Goethe's "The Metamorphosis of Plants" (1790), "Metamorphosis of Animals" (1806), and Elective Affinities (1809) are to be viewed as a three-part treatise on metamorphology or studies on the similarities of form. [1]
