Aboriginal Australians, Pacific Islanders carry DNA of unknown human species, research analysis suggests

People from Papua New Guinea and north-east Australia carry small amounts of DNA of an unidentified, extinct human species, a new research analysis has suggested.

The analysis suggests the DNA is unlikely to come from Neanderthals or Denisovans, but from a third extinct hominid, previously unknown to archaeologists.

Statistical geneticist Ryan Bohlender and his team investigated the percentages of extinct hominid DNA in modern humans. They found discrepancies in previous analyses and found that interbreeding between Neanderthals and Denisovans was not the whole story to our ancestors' genetic makeup.
