The cave was incredibly hard to access, so Berger and other researchers put out a call on social media.
They were looking for a team that had the physical capability and stature to enter the Dinaledi chamber — as well as the academic training required to identify and excavate precious fossils that could tell the story of the hominins that preceded us on this planet.
This chamber has only been explored over the past two years, and the remarkable findings within are being revealed for the first time today.
One of the most remarkable things about this discovery is that researchers think that the bones were found where they were because these human ancestors buried bodies in this chamber intentionally, depositing them there over a period of time.
Deep inside the Rising Star cave system, 30 miles northwest of Johannesburg, South Africa, there's a hidden chamber that's almost impossible to reach.
