Paleoanthropology in the context of Science book

The recent African origin of modern humans or the "Out of Africa" theory (OOA) holds that present-day humans outside Africa descend mainly from a single expansion of anatomically modern humans (Homo sapiens) from Africa about 70,000–50,000 years ago. It is the most widely accepted paleo-anthropological model of the geographic origin and early migration of the human species.

This expansion follows the early expansions of hominins out of Africa, accomplished by Homo erectus and then Homo neanderthalensis.

Evolutionary anthropology, the interdisciplinary study of the evolution of human physiology and human behaviour and of the relation between hominids and non-hominid primates, builds on natural science and on social science. Various fields and disciplines of evolutionary anthropology include:

• human evolution and anthropogeny
• paleoanthropology and paleontology of both human and non-human primates
• primatology and primate ethology
• the sociocultural evolution of human behavior, including phylogenetic approaches to historical linguistics
• the cultural anthropology and sociology of humans
• the archaeological study of human technology and of its changes over time and space
• human evolutionary genetics and changes in the human genome over time
• the neuroscience, endocrinology, and neuroanthropology of human and primate cognition, culture, actions and abilities
• human behavioural ecology and the interaction between humans and the environment
• studies of human anatomy, physiology, molecular biology, biochemistry, and differences and changes between species, variation between human groups, and relationships to cultural factors

Evolutionary anthropology studies both the biological and the cultural evolution of humans, past and present. Based on a scientific approach, it brings together fields such as archaeology, behavioral ecology, psychology, primatology, and genetics. As a dynamic and interdisciplinary field, it draws on many lines of evidence to understand the human experience, past and present.

Homo ergaster is an extinct species or subspecies of archaic humans who lived in Africa in the Early Pleistocene. Whether H. ergaster constitutes a species of its own or should be subsumed into H. erectus is an ongoing and unresolved dispute within palaeoanthropology. Proponents of synonymisation typically designate H. ergaster as "African Homo erectus" or "Homo erectus ergaster". The name Homo ergaster roughly translates to "working man", a reference to the more advanced tools used by the species in comparison to those of their ancestors. The fossil range of H. ergaster mainly covers the period of 1.7 to 1.4 million years ago, though a broader time range is possible. Though fossils are known from across East and Southern Africa, most H. ergaster fossils have been found along the shores of Lake Turkana in Kenya. There are later African fossils, some younger than 1 million years ago, that indicate long-term anatomical continuity, though it is unclear if they can be formally regarded as H. ergaster specimens. As a chronospecies, H. ergaster may have persisted to as late as 600,000 years ago, when new lineages of Homo arose in Africa.

Those who believe H. ergaster should be subsumed into H. erectus consider there to be too little difference between the two to separate them into distinct species. Proponents of keeping the two species as distinct cite morphological differences between the African fossils and H. erectus fossils from Asia, as well as early Homo evolution being more complex than what is implied by subsuming species such as H. ergaster into H. erectus. Additionally, morphological differences between the specimens commonly seen as constituting H. ergaster might suggest that H. ergaster itself does not represent a cohesive species. Regardless of their most correct classification, H. ergaster exhibit primitive versions of traits later expressed in H. erectus and are thus likely the direct ancestors of later H. erectus populations in Asia. Additionally, H. ergaster is likely ancestral to later hominins in Europe and Africa, such as modern humans and Neanderthals.

The Olduvai Gorge or Oldupai Gorge in Tanzania is one of the most important paleoanthropological localities in the world; the many sites exposed by the gorge have proven invaluable in furthering understanding of early human evolution. A steep-sided ravine in the Great Rift Valley that stretches across East Africa, it is about 48 km (30 mi) long, and is located in the eastern Serengeti Plains within the Ngorongoro Conservation Area in the Olbalbal ward located in Ngorongoro District of Arusha Region, about 45 kilometres (28 miles) from Laetoli, another important archaeological locality of early human occupation. The British/Kenyan paleoanthropologist-archeologist team of Mary and Louis Leakey established excavation and research programs at Olduvai Gorge that achieved great advances in human knowledge. The site is registered as one of the National Historic Sites of Tanzania.

The gorge takes its name from the Maasai word oldupai which means "the place of the wild sisal" as the East African wild sisal (Sansevieria ehrenbergii) grows abundantly throughout the gorge area. Twenty-five kilometers downstream of Lake Ndutu and Lake Masek, the gorge is the result of up to 90 m (300 ft) erosion cutting into the sediments of a Pleistocene lake bed. A side gorge, originating from Lemagrut Mountain, joins the main gorge 8 km (5.0 mi) from the mouth. This side gorge follows the shoreline of a prehistoric lake, rich in fossils and early hominin sites. Periodic flows of volcanic ash from Olmoti and Kerimasi helped to ensure preservation of the fossils in the gorge.

Kamoya Kimeu (1938 – 20 July 2022) was a Kenyan paleontologist and curator, whose contributions to the field of paleoanthropology were recognised with the National Geographic Society's LaGorce Medal and with an honorary doctorate of science degree from Case Western Reserve University.

Marie Eugène François Thomas Dubois (French: [øʒɛn dybwɑ]; 28 January 1858 – 16 December 1940) was a Dutch paleoanthropologist and geologist. He earned worldwide fame for his discovery of Pithecanthropus erectus (later redesignated Homo erectus), or "Java Man". Dubois was the first anthropologist to embark upon a purposeful search for hominid fossils.

Sterkfontein (Afrikaans for Strong Spring) is a set of limestone caves of special interest in paleoanthropology located in Gauteng province, about 40 kilometres (25 mi) northwest of Johannesburg, South Africa, in the Muldersdrift area close to the town of Krugersdorp. The archaeological sites of Swartkrans and Kromdraai are in the same area. Sterkfontein is a South African National Heritage Site and was also declared a World Heritage Site in 2000. The area in which it is situated is known as the Cradle of Humankind. The Sterkfontein Caves are also home to numerous wild African species including Belonogaster petiolata, a wasp species of which there is a large nesting presence.

Numerous early hominin remains have been found at the site over the last few decades. These have been attributed to Australopithecus, early Homo and Paranthropus.

The Solo River (known in Indonesian as the Bengawan Solo, with Bengawan being an Old Javanese word for river, and Solo derived from the old name for Surakarta) is the longest river in the Indonesian island of Java. It is approximately 600 km (370 mi) in length.

Apart from its importance as a watercourse to the inhabitants and farmlands of the eastern and northern parts of the island, it is a renowned region in paleoanthropology circles. Many discoveries of early hominid remains (dating from 100,00 to 1.5 million years ago) have been made at several sites in its valleys, especially at Sangiran, including that of the first early human fossil found outside of Europe, the so-called "Java Man" skull, discovered in 1891.

Hominization, also called anthropogenesis, refers to the process of becoming human, and is used in somewhat different contexts in the fields of paleontology and paleoanthropology, archaeology, philosophy, theology, and mythography. In the latter three fields, the alternative term anthropogony has also been used. Both anthropogenesis and anthropogony sometimes instead refer to the related subject of human evolution.

Anthropometry (/ænθrəˈpɒmɪtrɪ/ , from Ancient Greek ἄνθρωπος (ánthrōpos) 'human' and μέτρον (métron) 'measure') refers to the measurement of the human individual. An early tool of physical anthropology, it has been used for identification, for the purposes of understanding human physical variation, in paleoanthropology and in various attempts to correlate physical with racial and psychological traits. Anthropometry involves the systematic measurement of the physical properties of the human body, primarily dimensional descriptors of body size and shape. Since commonly used methods and approaches in analysing living standards were not helpful enough, the anthropometric history became very useful for historians in answering questions that interested them.

Today, anthropometry plays an important role in industrial design, clothing design, ergonomics and architecture where statistical data about the distribution of body dimensions in the population are used to optimize products. Changes in lifestyles, nutrition, and ethnic composition of populations lead to changes in the distribution of body dimensions (e.g. the rise in obesity) and require regular updating of anthropometric data collections.

Paleolithic religions are a set of spiritual beliefs and practices that are theorized to have appeared during the Paleolithic time period. Paleoanthropologists Andre Leroi-Gourhan and Annette Michelson believe unmistakably religious behavior emerged by the Upper Paleolithic, before 30,000 years ago at the latest. However, behavioral patterns such as burial rites that one might characterize as religious — or as ancestral to religious behavior — reach back into the Middle Paleolithic, as early as 300,000 years ago, coinciding with the first appearance of Homo neanderthalensis and possibly Homo naledi.

Religious behavior is one of the hallmarks of behavioral modernity. There are several theories as to the moment this suite of behavioral characteristics fully coalesced. One theory links the germination of behavioral innovations to a cultural revolution among early modern humans, which coincided with their arrival to Europe 40,000 years ago. A variant of this model sees behavioral modernity as occurring gradually, beginning with the Middle Stone Age. According to a third theory, characteristics that define behavioral modernity are not unique to the Homo sapiens, but arose over a long period of time, among different human types, including Neanderthals.

Homo gautengensis is a species name proposed by anthropologist Darren Curnoe in 2010 for South African hominin fossils otherwise attributed to H. habilis, H. ergaster, or, in some cases, Australopithecus or Paranthropus. The fossils assigned to the species by Curnoe cover a vast temporal range, from about 1.8 million years ago to potentially as late as 0.8 million years ago, meaning that if the species is considered valid, H. gautengensis would be both one of the earliest and one of the longest lived species of Homo.

Since Curnoe's 2010 description, recognition of the species has been limited. The classification of most of the fossils referred to H. gautengensis was controversial before the description of the species and continue to be controversial to this day. Some palaeoanthropologists have gone as far as to declare that there is little reason to consider H. gautengensis a valid taxon.

Baishiya Karst Cave (Chinese: 白石崖溶洞) is a high-altitude paleoanthropological site and a Tibetan Buddhist sanctuary located on the northeastern edge of the Tibetan Plateau in Xiahe County, Gansu, China. This karst cave is the site of the discovery of the earliest hominin fossil found on the Tibetan Plateau, the Xiahe mandible. The mandible, by way of palaeoproteomic analysis, is the first confirmed discovery of a Denisovan fossil outside of Denisova Cave. This fossil discovery shows that archaic hominins were present in a high-altitude, low-oxygen environment by around 160,000 years ago.

Ngorongoro Conservation Area (UK: /(ə)ŋˌɡɔːrəŋˈɡɔːroʊ/, US: /ɛŋˌɡɔːroʊŋˈɡɔːroʊ, əŋˌɡoʊrɔːŋˈɡoʊroʊ/) is a protected area and a UNESCO World Heritage Site located in Ngorongoro District, 180 km (110 mi) west of Arusha City in Arusha Region, within the Crater Highlands geological area of northeastern Tanzania. The area is named after Ngorongoro Crater, a large volcanic caldera within the area. The Ngorongoro Conservation Area Authority (NCAA), which administers the Ngorongoro Conservation Area (NCA), is an arm of the Tanzanian government and its boundaries follow the boundary of the Ngorongoro District in the Arusha Region. The western portion of the park abuts the Serengeti National Park (SNP). The area comprising the NCA, SNP, and Kenya's Maasai Mara game reserve is home to Great Migration, a massive annual migration of millions of wildebeest, zebras, gazelles, and other animals. The NCA also contains Olduvai Gorge, one of the most important paleoanthropological sites in the world.

Ngorongoro Conservation Area is one of the most popular attractions in Tanzania with 752,232 tourists visiting it in 2023.

The PanAfrican Archaeological Association (PAA) is a pan-African professional organisation for archaeologists, geologists and palaeoanthropologists.

The Cradle of Humankind is a paleoanthropological site that 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 known concentration of human ancestral remains anywhere in the world. The site currently occupies 47,000 hectares (120,000 acres) 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.

According to the South African Journal of Science, Bolt's Farm is the place where the earliest primates were discovered. Bolt's Farm was heavily mined for speleothem (calcium carbonate from stalagmites, stalactites, and flowstones) in the terminal nineteenth and early twentieth centuries.

Trinil is a palaeoanthropological site on the banks of the Bengawan Solo in Kedunggalar District, Ngawi, Indonesia. It was at this site in 1891 that the Dutch anatomist Eugène Dubois discovered the first early hominin remains to be found outside of Europe: the famous "Java Man" (Homo erectus erectus) specimen.
