Title: The adaptive value of tool-aided defense against wild animal attacks
Overview: This study of modern news accounts of wild animal attacks on humans revealed that the uniquely human ability to pick up a tool, whether a stick, stone, knife, or gun, and defend against attacking animals prevents injury and death. The findings suggest that early human ancestors who were the most skilled tool users would have survived animal attacks at higher rates and thus natural selection would have favored tool use as a way of life.
