"They were found deep in a cave system in South Africa by a team led by Lee Berger from Wits University.
In an interview, he now says the remains are probably just 200,000 to 300,000 years old.
Although its anatomy shares some similarities with modern people, other anatomical features of Homo naledi hark back to humans that lived in much earlier times - some two million years ago or more.
"These look like a primitive form of our own genus - Homo. It looks like it might be connected to early Homo erectus, or Homo habilis, Homo rudolfensis," said Prof Berger's colleague, John Hawks, from the University of Wisconsin.
[The remains] are obviously at an age where we have every reason to think there might be some chance. The cave is relatively warm compared to the cold caves in northern Europe and Asia where we have really good DNA preservation," said Prof Hawks.
