The Cradle of Humankind was declared a World Heritage Site by UNESCO in 1999.[1] It is about 50 kilometres northwest of JohannesburgSouth Africa in the Gauteng province. This site currently occupies 47,000 hectares (180 sq mi)[2] and it contains a complex of limestone caves.

The Sterkfontein Caves contain the discovery of a 2.3-million-year-old fossil Australopithecus africanus (nicknamed "Mrs. Ples"), found in 1947 by Robert Broom and John T. Robinson. The find helped corroborate the 1924 discovery of the juvenile Australopithecus africanus skull, "Taung Child", by Raymond Dart, at Taung in the North West Province of South Africa, where excavations still continue.

Nearby the site, but not in the site, the Rising Star Cave system contains the Dinaledi Chamber (chamber of stars) in which were discovered fifteen fossil skeletons of an extinct species of hominin, provisionally namedHomo naledi.

Sterkfontein alone has produced more than a third of early hominid fossils ever found prior to 2010.[3] The Dinaledi Chamber contains over 1500 H. naledi fossils, the most extensive discovery of a single hominid species ever found in Africa.[4]

Etymology[edit]

The name Cradle of Humankind reflects the fact that the site has produced a large number of (as well as some of the oldest) hominin fossils ever found, some dating back as far as 3.5 million years ago.[5]

History of discoveries[edit]

Australopithecus africanus (Hominid Reconstruction).

In 1935, Robert Broom found the first ape-man fossils at Sterkfontein and began work at this site. In 1938, a young schoolboy, Gert Terrblanche, brought Raymond Dart fragments of a skull from nearby Kromdraai which later were identified as Paranthropus robustus. Also in 1938, a single ape-man tooth was found at the Cooper's site between Kromdraai and Sterkfontein. In 1948, the Camp-Peabody Expedition from the United States worked at Bolts Farm and Gladysvale looking for fossil hominids but failed to find any. Later in 1948, Robert Broom identified the first hominid remains from Swartkrans cave. In 1954, C.K. Brain began working at sites in the Cradle including Coopers and he soon would initiate his three-decade work at Swartkrans cave which would result in the recovery of the second largest sample of hominid remains from the Cradle. The oldest controlled use of fire was also discovered at Swartkrans and dated to over 1 million years ago.[citation needed]

In 1966, Phillip Tobias began his excavations of Sterkfontein which are still continuing and are the longest continuously running fossil excavations in the world. In 1991, Lee Berger of the University of the Witwatersranddiscovered the first hominid specimens from the Gladysvale site making this the first new early hominid site to be discovered in South Africa in 48 years. In 1994, Andre Keyser discovered fossil hominids at the site of Drimolen. In 1997, Kevin Kuykendall and Colin Menter of the University of the Witwatersrand found two fossil hominid teeth at the site of Gondolin. Also in 1997, the near-complete Australopithecus skeleton of "Little Foot", dating to around 3.3 million years ago (although more recent dates suggest it is closer to 2.5 million years ago), was discovered by Ron Clarke. In 2001, Steve Churchill of Duke University and Lee Berger found early modern human remains at Plovers Lake. Also in 2001, the first hominid fossils and stone tools were discovered in-situ at Coopers. In 2008, Lee Berger discovered the partial remains of two hominids (Australopithecus sediba) in the Malapa Fossil Site that lived between 1.78 and 1.95 million years ago.

In October 2013, Lee Berger of the University of the Witwatersrand commissioned geologist Pedro Boshoff to investigate cave systems in the Cradle of Humankind for the express purpose of discovering more fossil hominin sites. Cavers Rick Hunter and Steven Tucker discovered hominid fossils in a previously unexplored area of the Rising Star/Westminster Cave System assigned site designation UW-101. In November 2013, Lee Berger led a joint expedition of the University of the Witwatersrand and National Geographic Society to the Rising Star Cave System near Swartkrans. In just three weeks of excavation, the six-woman international team of advance speleological scientists (K. Lindsay Eaves, Marina Elliott, Elen Feuerriegel, Alia Gurtov, Hannah Morris, and Becca Peixotto), chosen for their paleoanthropological and caving skills, as well as their small size, recovered over 1,200 specimens of a presently unidentified fossil hominin species. The site is still in the process of being dated. In September 2015, Lee Berger and the University of Witwatersrand, in collaboration with National Geographic, announced the discovery of a new species of human relative, namedHomo naledi, from UW-101.[6][7][8] Most remarkably, besides shedding light on the origins and diversity of our genus, H. naledi also appears to have intentionally deposited bodies of its dead in a remote cave chamber, a behaviour previously thought limited to humans.[9][10] In the last days of the Rising Star Expedition, cavers Rick Hunter and Steven Tucker discovered additional fossil hominid material in another portion of the cave system. Preliminary excavations at this site, designated UW-102, have begun and yielded complete hominid fossil material of its own. It is unknown what the relationship of sites 101 and 102 is.[11][12][13]
