Now, Dillehay, of Vanderbilt University in Nashville, has been lured back—and he is preparing for renewed debate.He reports in If his team is correct, the discovery will “shake up both the archaeology and genomics of the peopling of the Americas,” says archaeologist Jon Erlandson of the University of Oregon in Eugene.And the find raises questions about the North American record, where no one has found widely accepted evidence of occupation before 14,300 years ago.
Humans settled in South America in a single wave of migration not long after their ancestors first crossed from Siberia into the Western Hemisphere during the last ice age, genetic evidence suggests.
The finding, based on DNA from the remains of five ancient humans who lived high in the Peruvian Andes, also hints at how ancient Andeans evolved to thrive at altitudes of more than 4,000 metres.
Historical archaeologists have learned that excavated ceramics can be used to date the sites they study.
The most useful ceramics for dating are the glazed, relatively highly fired, fine-bodied earthenwares common since the late eighteenth century.
rchaeologist Tom Dillehay didn’t want to return to Monte Verde.
Decades ago, his discoveries at the famous site in southern Chile showed that humans occupied South America by 14,500 years ago, thousands of years earlier than thought, stirring a long and exhausting controversy.The inscriptions in the Archaeological Museum range from a few words in length to a long epitaph for a woman that was written in verse and quotes Cato and Seneca.Traditionally, Roman inscriptions were addressed to the Manes, the spirits of the dead who were thought to still reside in or around the tomb.It was characterized by large bifaces, particularly hand axes.This tool-making technology was a more complex way of making stone tools than the earlier Oldowan technology.Presented on 16 April at the annual meeting of the Society for American Archaeology (SAA) in San Francisco, California, the research sheds light on the last major continental migration in human prehistory — and one of the least understood.
