Australopithecus is a genus of early hominins that existed in Africa during the Pliocene and Early Pleistocene. The genera Homo, Paranthropus, and Kenyanthropus evolved from some Australopithecus species. Australopithecus is a member of the subtribe Australopithecina, which sometimes also includes Ardipithecus, though the term "australopithecine" is sometimes used to refer only to members of Australopithecus. Species include A. garhi, A. africanus, A. sediba, A. afarensis, A. anamensis, A. bahrelghazali and A. deyiremeda. Debate exists as to whether some Australopithecus species should be reclassified into new genera, or if Paranthropus and Kenyanthropus are synonymous with Australopithecus, in part because of the taxonomic inconsistency.
Australopithecus afarensis is an extinct species of australopithecine which lived from about 3.9–2.9 million years ago (mya) in the Pliocene of East Africa. The first fossils were discovered in the 1930s, but major fossil finds would not take place until the 1970s. From 1972 to 1977, the International Afar Research Expedition—led by anthropologists Maurice Taieb, Donald Johanson and Yves Coppens—unearthed several hundreds of hominin specimens in Hadar, Ethiopia, the most significant being the exceedingly well-preserved skeleton AL 288-1 ("Lucy") and the site AL 333. Beginning in 1974, Mary Leakey led an expedition into Laetoli, Tanzania, and notably recovered fossil trackways. In 1978, the species was first described, but this was followed by arguments for splitting the wealth of specimens into different species given the wide range of variation which had been attributed to sexual dimorphism. A. afarensis probably descended from A. anamensis and is hypothesised to have given rise to Homo, though the latter is debated.
The Cradle of Humankind is a paleoanthropological site and is located about 50 km (31 mi) northwest of Johannesburg, South Africa, in the Gauteng province. Declared a World Heritage Site by UNESCO in 1999, the site is home to the largest concentration of human ancestral remains anywhere in the world. The site currently occupies 47,000 hectares (180 sq mi) and contains a complex system of limestone caves. The registered name of the site in the list of World Heritage Sites is Fossil Hominid Sites of South Africa.
Laetoli is a pre-historic site located in Enduleni ward of Ngorongoro District in Arusha Region, Tanzania. The site is dated to the Plio-Pleistocene and famous for its Hominina footprints, preserved in volcanic ash. The site of the Laetoli footprints is located 45 km south of Olduvai gorge. The location and tracks were discovered by archaeologist Mary Leakey and her team in 1976, and were excavated by 1978. Based on analysis of the footfall impressions "The Laetoli Footprints" provided convincing evidence for the theory of bipedalism in Pliocene Hominina and received significant recognition by scientists and the public. Since 1998, paleontological expeditions have continued under the leadership of Amandus Kwekason of the National Museum of Tanzania and Terry Harrison of New York University, leading to the recovery of more than a dozen new Hominina finds, as well as a comprehensive reconstruction of the paleoecology. The site is a registered National Historic Sites of Tanzania.
The Tugen Hills are a series of hills in Baringo County, Kenya. They are located in the central-western portion of Kenya.
Happisburgh is a village civil parish in the English county of Norfolk. The village is on the coast, to the east of a north–south road, the B1159 from Bacton on the coast to Stalham. It is a nucleated village. The nearest substantial town is North Walsham 6 miles (10 km) to the west.
A fossil track or ichnite is a fossilized footprint. This is a type of trace fossil. A fossil trackway is a sequence of fossil tracks left by a single organism. Over the years, many ichnites have been found, around the world, giving important clues about the behaviour of the animals that made them. For instance, multiple ichnites of a single species, close together, suggest 'herd' or 'pack' behaviour of that species.
Footprints are the impressions or images left behind by a person walking or running. Hoofprints and pawprints are those left by animals with hooves or paws rather than feet, while "shoeprints" is the specific term for prints made by shoes. They may either be indentations in the ground or something placed onto the surface that was stuck to the bottom of the foot. A "trackway" is a set of footprints in soft earth left by a life-form; animal tracks are the footprints, hoofprints, or pawprints of an animal.
The Ciampate del Diavolo is a locality near the extinct Roccamonfina volcano in northern Campania, Italy. It is named after fossilised footprints preserved in pyroclastic flow deposits that have been dated to around 350,000 years ago. They have been attributed to bipedal hominids, possibly Homo heidelbergensis, which is known to have inhabited the region at the time.
The Ancient footprints of Acahualinca exist in Managua, Nicaragua near the southern shore of Lake Managua. The region was once called "El Cauce". The tracks are fossil Late Holocene human footprints left behind in volcanic ash and mud, which solidified about 2,120±120 years ago, shortly after the group of up to 15 people passed by.
Lee Rogers Berger is an American-born South African paleoanthropologist and National Geographic Explorer-in-Residence. He is best known for his discovery of the Australopithecus sediba type site, Malapa; his leadership of Rising Star Expedition in the excavation of Homo naledi at Rising Star Cave; and the Taung Bird of Prey Hypothesis.
Gladysvale Cave is a fossil-bearing breccia filled cave located about 13 kilometres (8.1 mi) northeast of the well-known South African hominid-bearing sites of Sterkfontein and Swartkrans and about 45 kilometres (28 mi) north-northwest of Johannesburg, South Africa. It is situated within the Cradle of Humankind World Heritage Site and is itself a South African National Heritage Site.
Plovers Lake Cave is a fossil-bearing breccia filled cavity in South Africa. The cave is located about 4 km Southeast of the well known South African hominid-bearing sites of Sterkfontein and Kromdraai and about 36 km Northwest of the City of Johannesburg, South Africa. Plovers Lake has been declared a South African National Heritage Site.
Hoedjiespunt is a Middle Pleistocene aged hominid fossil-bearing site on the West coast of South Africa, near the town of Saldanha Bay. The site is an ancient brown hyena lair dug into the side of a sand dune, located on a peninsula overlooking the Atlantic Ocean. The site became fossilized under a large calcrete formation around 280,000 years ago, at which time it was likely several kilometers from the ocean.
The evolution of human bipedalism, which began in primates approximately four million years ago, or as early as seven million years ago with Sahelanthropus, or approximately twelve million years ago with Danuvius guggenmosi, has led to morphological alterations to the human skeleton including changes to the arrangement, shape, and size of the bones of the foot, hip, knee, leg, and the vertebral column. These changes allowed for the upright gait to be overall more energy efficient in comparison to quadrupeds. The evolutionary factors that produced these changes have been the subject of several theories that correspond with environmental changes on a global scale.
Langebaan is a town in the Western Cape province of South Africa on the eastern shore of Langebaan Lagoon.
Ileret is a village in Marsabit County, Kenya. It is located in Northern Kenya, on the eastern shore of Lake Turkana, north of Sibiloi National Park and near the Ethiopian border.
The Florisbad Skull is an important human fossil of the early Middle Stone Age, representing either late Homo heidelbergensis or early Homo sapiens. It was discovered in 1932 by T. F. Dreyer at the Florisbad site, Free State Province, South Africa.
Malapa is a fossil-bearing cave located about 15 kilometres (9.3 mi) northeast of the well known South African hominid-bearing sites of Sterkfontein and Swartkrans and about 45 kilometres (28 mi) north-northwest of Johannesburg, South Africa. It is situated within the Cradle of Humankind World Heritage Site.
The Happisburgh footprints were a set of fossilized hominid footprints that date to the end of the Early Pleistocene, around 950-850,000 years ago. They were discovered in May 2013 in a newly uncovered sediment layer of the Cromer Forest Bed on a beach at Happisburgh in Norfolk, England, and carefully photographed in 3D before being destroyed by the tide shortly afterwards.
