Homo naledi discovery 'to take time to interpret'
Scientists who yesterday presented a new species of human ancestor say the new fossil find will take decades to interpret.
The species named Homo naledi was discovered in caves at the Cradle of Humankind just outside Johannesburg.
The team led by Wits paleoanthropologist Professor Lee Berger says the hominid appears to have deliberately buried the bodies of its dead in the remote cave chamber.
Professor of Geology at the James Cook University in Australia Paul Dirks says they have been trying to figure out how they got into the caves.
