(CNN)Men hunted. Women gathered. That has long been the prevailing view of our prehistoric ancestors.
But the discovery of a woman buried 9,000 years ago in the Andes Mountains with weapons and hunting tools, and an analysis of other burial sites in the Americas challenges this widely accepted division of labor in hunter-gatherer society.
The woman, thought to be between 17 and 19 years old when she died, was buried with items that suggested she hunted big-game animals by spear throwing -- stone projectile points for felling large animals, a knife and flakes of rock for removing internal organs, and tools for scraping and tanning hides.
