The American Continent was the last continent to be colonized by the human species, and how this settlement occured is still an intense debate in the scientific community. After entering the American Continent, about 15.000 Years Before the Present (YBP), the first Americans expanded rapidly, reaching South America around 12,000 YBP. The continuous occupation of the South American Atlantic Coast begins during the Holocene (~ 11,500 YBP), a few thousand years after the human entrance in the continent. The populations that occupied this region, called Sambaqueiros, little is known about its evolutionary history and genetic proximity to the present Native American populations. The present project aims to investigate the population dynamics of the Brazilian coast settlement, as well as trying to establish the genetic relations between the paleo populations that inhabited this region and the current Native Americans. To do so, we will generate data from mitochondrial genomes and SNPs arrays from 22 paleo individuals from Sambaquis and 100 Native Americans from different populations belonging to several linguistic stocks.
