South Africa contains some of the oldest archaeological and human fossil sites in the world. Extensive fossil remains have been recovered from a series of caves in Gauteng Province. The area is a UNESCO World Heritage site and has been termed the Cradle of Humankind. The sites include Sterkfontein, which is one of the richest hominin fossil sites in the world. Other sites include Swartkrans, Gondolin Cave Kromdraai, Coopers Cave and Malapa. The first hominin fossil discovered in Africa, the Taung Child was found near Taung in 1924. Further hominin remains have been recovered from the sites of Makapansgat in Limpopo, Cornelia and Florisbad in the Free State, Border Cave in KwaZulu-Natal, Klasies River Mouth in eastern Cape and Pinnacle Point, Elandsfontein and Die Kelders Cave in Western Cape. These sites suggest that various hominid species existed in South Africa from about three million years ago starting with Australopithecus africanus. These were succeeded by various species, including Australopithecus sediba, Homo ergaster, Homo erectus, Homo rhodesiensis, Homo helmei and modern humans, Homo sapiens.
