In “Social Statics”[1850], Herbert Spencer (1820-1903) said “Progress, therefore, is not an accident, but a necessity... It is a part of nature.” Has progress been made in developmental field theory and clinical practice? One is tempted to say yes, knowing that recently the Canadian College of Medical Genetics asked the candidates for the written examination to define “developmental field.” When frustrated with apparently slow progress in a field, the historically minded are liable to reach for the earlier formulations of knowledge on their shelves. Thus, the 5th edition of Oscar Hertwig’s Lehrbuch der Entwickelungsgeschichte des Menschen und der Wirbelthiere (Textbook of Embryology of Man and Vertebrates [1896], first published exactly 100 years ago), in Chapter 4,“General Discussion of Developmental Principles,” addresses only embryologic events and inferred mechanisms without attempting a developmental theory. He summarizes “classical” knowledge up to that time:Thus, study of the ontogeny of an organism involves primarily two aspects; one is the study of morphogenesis, the other... of histologic differentiation. We may add immediately that in higher organisms morphogenesis take place primarily in the beginning stges, histologic differentiation in the later stages (Endstadien) of development. Knowledge of these guiding principles will make it much easier to understand the other developmental processes.
