Quoted: Professor T. Douglas Price from the University of Wisconsin-Madison, one of Schroeder?s colleagues, recently attempted to pin down the 49 settlers? birthplaces by analyzing the carbon, oxygen and strontium isotope ratios in their tooth enamel. These elemental signatures are locked in tooth enamel during childhood and vary depending on the diet, climate, altitude and local geology of a person?s homeland. Last year, Price noted that the isotopic ratios in seven of the skeletons suggested they could have African origins.
