Violence in Mexico | Fossils in ancient times

Editor's note

On the campaign trail Mexico’s new President Andrés Manuel López Obrador floated several possibilities to reduce crime without using law enforcement. These included granting amnesty to low-level criminals and negotiating with crime bosses. Most of these plans have faded since he took office, as he’s shifted to more traditional law-and-order approaches. But, Angélica Durán-Martínez argues, violence in Mexico is so pervasive that the country must consider every available option.

Southern Africa is critically important in the origin of modern humans, and has a rich fossil record. Yet, little is known about how pre-scientific cultures interpreted the geological and fossil phenomena they encountered in the world around them. Charles Helm explains how he and his colleagues set out to fill this knowledge gap.
