EVAN M. GAROFALO, then a student at Johns Hopkins University, Baltimore, Maryland, received funding in May 2010, to aid research on 'Genetic and Environmental Effects on Skeletal Growth Variation,' supervised by Dr. Christopher Britton Ruff. Adult morphology and variation are the result of complex interactions between genetic and environmental effects during the growth process. Health, disease, and socio-economic status are important for the regulation of the growth trajectory, particularly during infancy and early childhood. However, genetic differences, increasing in prominence during adolescence, contribute significantly to growth profiles and the attainment of adult morphology. Thus, the primary goal of this project is to partition the relative importance of environmental and genetic influences on the timing and nature of the growth process. Multiple skeletal variables, each differentially sensitive to environmental and genetic influence, were examined to assess the skeletal growth of individuals from St. Peter's Church (Barton-upon-Humber, UK) -- a socially stratified and relatively genetically homogeneous population. In this study, there is no effect of socioeconomic status on long bone length, stature, body mass or articular dimensions. However, long bone diaphyseal cross-sectional cortical and medullary areas (considered to be highly environmentally sensitive) show marked differences, primarily during infancy and early childhood, with reduced or no differences for young adults. Early results and palaeopathological observations suggest socioeconomic groups differences may be related to sustaining more prolonged durations of metabolic distress in the higher socioeconomic subadult sample.
