Form and Function: A Contribution to the History of Animal Morphology
l is a scientific publication written in the early 20th century. The book explores the historical development and fundamental concepts of animal morphology, addressing various approaches to under standing the relationship between form and function in biological organ isms. The opening of the work sets the stage for a discussion of the evolu tion of comparative anatomy from ancient to modern times. Russell intro duces key figures in the field, beginning with Alcmaeon and Aristotle, elab orating on their contributions to anatomical observation and classification. The text highlights Aristotle's foundational role in comparative anatomy, emphasizing his recognition of common structures across different species while also considering functional adaptations. Through this historical lens, Russell aims to illustrate the continuity of thought in animal morphology and addresses the interplay of various morphological theories that have de veloped over centuries the first name of which the history of anatomy keeps record is that of Al cmaeon, a contemporary of Pythagoras (6th century B.C.). His inter ests appear to have been rather physiological than anatomical. He traced the chief nerves of sense to the brain, which he considered to be the seat of the soul, and he madesomegoodguessesatthemechanismoftheorgansof special sense. He showed that, contrary to the received opinion, the seminal fluid did not originate in the spinal cord. Two comparisons are recorded of his, one that puberty is the equivalent of the flowering time in plants, the other that milk is the equivalent of white of egg. 1] Both show his bias to wards looking at the functional side of living things. The latter comparison reappears in Aristotle. A century later Diogenes of Apollonia gave a description of the venous sys tem. Hetooplacedtheseatofsensation in the brain. He assumed avital air in all living things, being in this influenced by Anaximenes whose primitive matter was infinite air. In following out this thought he tried to prove that both fishes and oysters have the power of breathing.
