This study argues that morphology was integral to the life sciences of the 19th century. It traces the development of morphological research in German universities and illuminates significant institutional and intellectual changes in 19th-century German biology. Although there were neither professors of morphology nor a morphologists' society, morphologists achieved influence by "colonizing" niches in a variety of disciplines. Scientists in anatomy, zoology, natural history, and physiology considered their work morphological, and the term encompassed research that today might be classified as embryology, systematics, functional morphology, comparative physiology, ecology, behaviour, evolutionary theory, or histology. Nyhart draws on research notes, correspondence and other archival material to examine how these scientists responded to new ideas and to the work of colleagues.
She examines the intertwined histories of morphology and the broader biological enterprise, demonstrating that the study of form was central to investigations of such issues as the relationships between an animal's structure and function, between an organism and its environment, and between living species and their ancestors.
