A new study based on cutting-edge genetic analysis has revealed startling new information about South American migration patterns. By carrying out a complete genetic sequencing of DNA provided by human remains excavated in Brazil, researchers have pieced together a vision for how humans first settled South America and made inroads into resolving the Americas puzzle. Following the Clues to Understand South American Migration After leaving Africa in large numbers between 90,000 and 60,000 years ago, modern humans gradually spread all across the globe, leaving Antarctica as the only unsettled continent.
