Drought-related changes in two hunter-gatherer California populationsQuaternary Research (2002)
AbstractSkeletal remains from two California cemeteries bracketing a severe drought that began around 1200 yr B.P. are analyzed to determine drought-related quality of life changes in Native Americans. Cemetery 1 predates the drought at 2895 ± 160 yr B.P. to 1845 ± 90 yr B.P. and Cemetery 2 dates it at 1100 ± 90 yr B.P. to 1220 ± 200 yr B.P. Quality of life was assessed through femoral computerized tomography scan measures of cortical thickness, age at adult death, and pathology/trauma frequency. After controlling for age and sex differences, changes from Cemetery 1 to Cemetery 2 showed decreases in cortical thickness and age at death and increases in pathology and trauma frequency.
