The Valdivia culture is one of the oldest settled cultures recorded in the Americas. Remains of the Valdivia culture were discovered in on the western coast of Ecuador by the Ecuadorian archeologist Emilio Estrada, who continued to study this culture. American archeologists Clifford Evans and Betty Meggers joined him in the early s in studying the type-site. The Valdivia lived in a community that built its houses in a circle or oval around a central plaza. They were believed to have a relatively egalitarian culture of sedentary people who lived mostly off fishing, though they did some farming and occasionally hunted for deer to supplement their diet.
