A reprint of a classical work in the Princeton Legacy Library. Originally published in 1992.
For a wide spectrum of scientists from biomedical and dental researchers to primatologists and physical anthropologists, Emet Schneiderman offers the most accurate and up-to-date presentation of the normal growth of the lower facial skeleton in a primate species. His study is based on a sample of thirty-five captive rhesus monkeys, whose facial growth was traced over a ten-year period spanning from infancy to adulthood.
The author identifies the relative contribution of various sites of growth, quantifies the relative roles of different types of development – such as appositional and condylar – and sheds light on several long-standing controversies as to how the primate face grows. Unlike many of the traditional cephalometric measurements, the ones included in Facial Growth in the Rhesus Monkey were chosen to reflect the positional, dimensional, and localized remodeling changes that occur during ontogeny. Using a new statistical approach designed for longitudinal data, Schneiderman avoids the misleading information that has often resulted from older, cross-sectional statistical methods. Facial Growth in the Rhesus Monkey serves as a foundation for future experimental and normal studies in the rhesus monkey and, from a methodological standpoint, as a general model for future longitudinal growth studies.
