Trends in stature in the South Australian Aboriginal Murraylands.
Millennial and secular changes in body height of prehistoric and recent Aboriginal South Australians are investigated. Skeletal remains of 55 male and 40 female individuals who were excavated at Roonka on the River Murray were dated from 9800 to 100 years BP. Stature was reconstructed by using humerus, femur, and tibia ratios to stature derived from Abbie's (1975) data on living Aborigines and the Trotter-Gleser method for blacks. The respective averages were 1,652 mm and 1,665 mm for males and 1,527 mm and 1,549 mm for females. In 1996/1997, statures of 27 adult males and 21 adult females were measured in Aboriginal centers of Gerard and Raukkan (Point McLeay) on the Lower River Murray. These people, as far as it can be ascertained, are the descendants of the people from Roonka. Their statures were adjusted for the stature loss with age, so that the data represent young individuals (< or = 30 years of age). The average male stature was 1,712 mm, and the average female stature was 1,567 mm. Data collected by Wood Jones and Campbell in 1924 for Aboriginal South Australians show that young adult male stature was 1,668 mm (n=6), and female stature was 1,552 mm (n=4). Slopes of regressions of individual statures on radiocarbon dates and on dates of birth are not significantly different from zero. The same is true for regressions of individual long bone lengths on radiocarbon dates. It can be concluded that there was little change in stature of Aboriginal South Australians from prehistoric to recent times. Regressions of individual age-corrected heights on birth dates (1860-1980) of Aboriginal men and women measured in 1924 and in 1996 further indicate no significant increase in height in either sex.
