Archaic Denisovan and Neanderthal DNA that persists in modern Pacific islanders of Melanesia, far from the Siberian cave where Denisovan fossils have been found, is a source of information about early human history. Equally informative are genome regions where DNA from extinct, human-like species has vanished and been replaced with sequences unique to people. These large regions have genes for brain development, language and brain cell signalling. Retained archaic DNA in human genomes may confer infection-fighting advantages.
