Ancient Human Genes Found in Isolated South American Amazonian Tribes

’DNA from extinct human species such as Neanderthals and Denisovans was discovered by researchers studying the genomes of ancient South Americans. The study, which looked at ancient genomes from skeletal remains from Brazil, Panama, and Uruguay, also revealed the early South Americans’ transcontinental migration. This study is significant because Neanderthal or Denisovan ancestry has never been linked to ancient South Americans before. The scientists compared the genomes of prehistoric human remains discovered in South America to those discovered in North America. Alaskan remains were used as a stand-in for ancient Beringia. The researchers also used two ancient entire genomes recently sequenced from teeth discovered in northeast Brazil. In addition to the ancient human genomes studied, the researchers compared modern genomes from around the world as well as DNA sequences from Denisovan and Neanderthal bones from Siberia. According to the investigation, some of the Native American human bones
