In March 2008,
Lee Berger of the
University of the Witwatersrand, South Africa, undertook an exploration project in the Cradle of Humankind World Heritage site outside of Johannesburg, in order to map the known caves identified by him and his colleagues over the past several decades, and to place known fossil sites onto
Google Earth so that information could be shared with colleagues. The area is important as nearly a third of the entire evidence for human origins in Africa comes from just a few sites in this region, and the region is arguably one of the most explored areas in Africa for evidence of human origins, having been investigated continuously since the first discoveries were made there in 1935. At the beginning of this project, there were approximately 130 known cave sites in the region and around twenty fossil deposits. On 4 September 2008, Berger returned to the site with more than a dozen colleagues, where Berger discovered a second partial skeleton of an adult female. ==Recovered fossils==
