Economy
The Alto Ramirez group had a mixed economy that combined agriculture with gathering (of plants and mollusks), fishing, and hunting of sea and land animals. They grew maize, peppers, cassava, quinoa, beans and squash, using stone shovels to work the land and large baskets, called capachos, to carry their produce. They made flour by grinding up the plants they collected in stone mortars. On the sea, they used the same instruments employed by their coastal hunter-gatherer ancestors but for hunting on land they used an innovative implement, the spear thrower.
