MAROPENG - Details of a significant fossil discovery have been kept secret for years and are due to be unveiled at Maropeng in the Cradle of Humankind at 11am today.

Shortly thereafter, a global embargo on all information relating to the find will be released and a month-long public exhibition will open.

Professor Lee Berger led the expedition that unearthed a discovery, which now looks set to raise deep questions about what it means to be human.

The head of exploration at National Geographic says that what Berger and his team have achieved with the latest fossil discovery is something most scientists never achieve.

Discoveries like this in the past have fundamentally changed our understanding of human ancestry.

Deputy president Cyril Ramaphosa is set to receive a private viewing, and then will address the nation about the significance of the discovery.

Once the global embargo falls the entire world will be able to access all the information available about what has been discovered.

Wits University has described the find as a groundbreaking discovery of international importance.
