Abstract Details

2013, Master of Arts, Ohio State University, Anthropology.
Domestication of the extinct eastern North American crop, marshelder (Iva annua L. var. macrocarpa Jackson) is investigated through quantitative analysis of samples from archaeological sites. Change in marshelder achene (fruit) size over time sheds light on patterns of regional and subregional domestication processes and patterns of diffusion. The hypothesis that marshelder was introduced into the Cumberland Plateau of eastern Kentucky rather than domesticated in situ is evaluated through spatial and temporal statistical tests from measurements of achene size collected by researchers throughout eastern North America. Statistical analyses show that although there is some evidence for increased achene size under domestication, this pattern does not indicate a smooth and gradual trend. Patterns of variability in achene size, in contrast, seem to reflect geographical location rather than temporal placement. These data support an introduction of marshelder to eastern Kentucky from the Illinois River Valley, where the first domesticates are found.
