Metal artifacts in Southeast Asia challenge long-held archaeological theory
A photo of a metal artifact in the shape of a spear on a black background. In the foreground is a scale that runs from 0 to 5 cm.

An individual can create a stone tool or a pot without assistance, but creating a metal tool like the spear here is a group endeavor—and a complex one. Artifacts like this found in Thailand showed that such metal technology could be developed and exchanged using an economic model based on communities making decisions about how to participate in regional exchange systems.
