The scientific study of past material culture. The initial objective of archeology (often spelled archaeology) is to construct cultural chronologies that order past material culture into meaningful temporal segments. The intermediate objective is to…

Scientists have suggested a possible connection between ancient Neandertals (Homo neanderthalensis) and the severity of disease in patients affected by COVID-19. In short, certain genes acquired from Neandertals during instances of interbreeding…

The adaptation of an animal or plant through breeding in captivity to a life intimately associated with and advantageous to humans. Domesticated plants and animals differ genetically and morphologically from their wild counterparts, often in ways…

The earliest representatives of people anatomically similar to living humans that evolved from more archaic humans approximately 150,000–300,000 years ago. The general process by which early modern humans (Homo sapiens) emerged from late archaic…

A method of dating geological and archeological specimens by counting the radiation-damage tracks produced by spontaneous fission of uranium impurities in minerals and glasses. During fission two fragments of the uranium nucleus fly apart with high…

Fossil members of the group of primates constituting the apes. Apes and humans are closely related primates in the superfamily Hominoidea. The living hominoids are subdivided into the families Hylobatidae and Hominidae. The hylobatids, or lesser…

The earliest representatives of modern humans—those belonging to Homo sapiens—evolved from more archaic humans approximately 150,000–300,000 years ago in eastern Africa. During succeeding years, the geographical range of anatomically modern humans…

Extinct members of the order of mammals to which humans belong. All current classifications divide the living primates (order Primates) into two major groups (suborders) [Fig. 1]: the Strepsirhini (Strepsirrhini) or "lower" primates (lemurs,…

A species of fossil human from the Pleistocene representing a specialized side branch in human evolution in Africa and Eurasia. Homo erectus (Fig. 1) was a common, widespread, and long-surviving ancestor of modern humans (H. sapiens). Fossil remains…

The diversity of biological and genetic differences observed in the human population. Anthropologists study human biology to better understand the extent of human biological variability, to explain the mechanisms that create and pattern this…

The study of primate phylogeny and human evolution through the genetic information in the DNA of genomes and in the proteins that genes encode. The first studies in molecular anthropology used immunological and biochemical methods to obtain…

A group of late archaic humans (Homo neanderthalensis) from Europe, southwest Asia, and central Asia that immediately preceded the first modern humans in those regions. The closest evolutionary relatives of modern humans are the Neandertals (also…

The period of prehistoric culture whose basic defining attributes are the emergence of agriculture, animal domestication, and sedentary farmsteads or villages. This definition has evolved over the last century from the original characterization of…

The study of disease in the ancient past. Paleopathology is the investigation of ancient diseases and their origins. The term applies to any evidence of disease in any form of life, including both plants and animals. However, the research emphasis…

Over the course of history, smallpox has been among the most feared diseases of humankind. Caused by the variola virus (a DNA-containing member of the Poxviridae family) and spread by transfer through respiratory droplets during face-to-face…

A scientific discipline that applies principles of evolutionary biology to the study of animal and human social behavior. Sociobiology is a synthesis of ethology (the study of animal behavior), ecology, and evolutionary theory in which social…

Determination of the relative or absolute age of materials or objects by measurement of the degree of racemization of the amino acids present. With the exception of glycine, the amino acids found in proteins can exist in two isomeric forms called d-…

The observation, measurement, and explanation of human variability in time and space. Anthropology is a science concerned with the interrelations of the biological, cultural, geographical, and historical aspects of humankind, including modern human…

The systematic quantitative representation of the human body. Anthropometric techniques are used to measure the absolute and relative variability in size and shape of the human body. Instrumentation Depending on the objective, anthropometric…

The establishment of the temporal sequence of prehistoric events. An event can be defined as a duration of time during which certain features came together to form a set, for example, when certain materials were formed into an object (manufacturing…

Any member of an adaptively diverse group of extinct hominin species that inhabited Africa between approximately 4.2 million years ago (MYA) and 1.2 MYA. The term australopith is used in preference to the term australopithecine, which is sometimes…

The study of skeletal remains from archeological sites by biological (or physical) anthropologists. Bioarcheology differs in several ways from traditional skeletal research. Previous work focused on individual case studies (for example, individuals…

Relative and quantitative techniques used to arrange events in time and to determine the numerical age of events in history, geology, paleontology, archeology, paleoanthropology, and astronomy. Relative techniques allow the order of events to be…

The science that dates annual tree rings to their exact year of formation for study of modern, historical, and prehistorical events and environmental conditions. Trees are intimately bound to the environment, with their growth influenced by natural…

The scientific study of people, with their living and extinct primate relatives, using the evidence of teeth. Dental anthropologists include not only those trained in anthropology but also practicing dentists, anatomists, radiologists, forensic…

At the Woranso-Mille paleontological site in northern Ethiopia, researchers have discovered a 3.8 million-year-old cranium (skull) belonging to a primitive hominin known as Australopithecus anamensis. Initially unearthed in 2016, but not reported…

The application of physical anthropology theory and techniques to medicolegal questions. Forensic anthropology may also pertain to subdisciplines of anthropology, such as cultural anthropology, biological/physical anthropology, archaeology, and…

Ancient fossilized members of human beings and those species directly ancestral to modern humans. Fossil humans comprise all prehistoric skeletal remains of humans that are archeologically earlier than the Neolithic (necessarily an imprecise limit,…

The deoxyribonucleic acid of Homo neanderthalensis. Neandertals (also spelled Neanderthals) are the closest evolutionary relatives of modern humans. Based on fossil and archeological records, Neandertals are large-brained people with a distinct…

The prehistoric period when people made stone tools exclusively by chipping or flaking. John Lubbock proposed and defined the term Paleolithic, or Old Stone Age, in 1865 and also defined a subsequent stage, Neolithic or New Stone Age, during which…

The subfield of anthropology that deals with human and nonhuman primate evolution, the biological bases of human behavior, and human biological variability and its significance. Physical anthropology is a branch of anthropology that investigates the…

The apes are a branch of Old World primates, distinguished from monkeys by their mode of locomotion (arm swinging, rather than quadrupedal walking). It has long been known that humans are more closely related to apes than to other primates. However,…

The behavior of wild chimpanzees (Pan troglodytes) [Fig. 1] is fascinating because of its similarity to human behavior. These behavioral similarities are due in part to the close evolutionary relationship between chimpanzees and humans. Behavioral…

A new species of orangutan has been identified in the Batang Toru forest ecosystem in northern Sumatra, Indonesia. Genetic and morphological evidence, as well as behavioral data, have confirmed that the Tapanuli orangutan (Pongo tapanuliensis) is…

In the Rising Star cave system in South Africa, located about 48 kilometers (30 miles) north of Johannesburg, paleoanthropologists have unearthed an extensive collection of more than 1550 skeletal elements from at least 15 individuals that have…

In the Afar region of Ethiopia, paleoanthropologists unearthed a 2.8 million-year-old jawbone (mandible) that was provisionally assigned to the genus Homo [the genus of human beings, including modern humans (Homo sapiens) and other extinct species].…
