Summary

Archaeobotanist Dolores Piperno has used microscopic fossils of plants to trace the origins of agriculture in the Americas, for example last year reporting the earliest known maize (corn) from a valley in southern Mexico. For many researchers, her work on maize reconciled the genetic and archaeological evidence and ended a long debate about whether maize had been domesticated in the highlands or the lowlands. A key element behind Piperno's success, her admirers say, has been a determination to plant herself firmly on the scientific side of archaeology, a field that represents an often uneasy marriage between science and the humanities.
