Copper Artifacts Uncover Ancient Global Connections

Researchers from the University of Missouri and colleagues used geochemical analysis on copper objects to uncover centuries of previously unknown connections within the region. Chemical and isotopic analysis of copper artifacts from southern Africa has unveiled new cultural connections among the people living in the region between the 5th and 20th centuries. The data shows the interaction between these groups not only involved the movement of goods, but also flows of information and the sharing of technological practices that come with that exchange.
