Anthropology is the scientific study of humanity, concerned with human behavior, human biology, cultures, societies, and linguistics, in both the present and past, including past human species. Social anthropology studies patterns of behavior, while cultural anthropology studies cultural meaning, including norms and values. A portmanteau term sociocultural anthropology is commonly used today. Linguistic anthropology studies how language influences social life. Biological or physical anthropology studies the biological development of humans.
Biological anthropology, also known as physical anthropology, is a scientific discipline concerned with the biological and behavioral aspects of human beings, their extinct hominin ancestors, and related non-human primates, particularly from an evolutionary perspective. This subfield of anthropology systematically studies human beings from a biological perspective.
Race is a categorization of humans based on shared physical or social qualities into groups generally viewed as distinct within a given society. The term came into common usage during the 16th century, when it was used to refer to groups of various kinds, including those characterized by close kinship relations. By the 17th century, the term began to refer to physical (phenotypical) traits, and then later to national affiliations. Modern science regards race as a social construct, an identity which is assigned based on rules made by society. While partly based on physical similarities within groups, race does not have an inherent physical or biological meaning. The concept of race is foundational to racism, the belief that humans can be divided based on the superiority of one race over another.
Theodosius Grigorievich Dobzhansky was a prominent Russian and American geneticist and evolutionary biologist. He was a central figure in the field of evolutionary biology for his work in shaping the modern synthesis. Born in the Russian Empire, Dobzhansky emigrated to the United States in 1927, aged 27.
Nature versus nurture is a long-standing debate in biology and society about the balance between two competing factors which determine fate: genetics (nature) and environment (nurture). The alliterative expression "nature and nurture" in English has been in use since at least the Elizabethan period and goes back to medieval French.
Richard Charles Lewontin was an American evolutionary biologist, mathematician, geneticist, and social commentator. A leader in developing the mathematical basis of population genetics and evolutionary theory, he pioneered the application of techniques from molecular biology, such as gel electrophoresis, to questions of genetic variation and evolution.
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:
Niche construction is the process by which an organism alters its own local environment. These alterations can be a physical change to the organism’s environment or encompass when an organism actively moves from one habitat to another to experience a different environment. Examples of niche construction include the building of nests and burrows by animals, and the creation of shade, influencing of wind speed, and alternation of nutrient cycling by plants. Although these alterations are often beneficial to the constructor, they are not always.
Researchers have investigated the relationship between race and genetics as part of efforts to understand how biology may or may not contribute to human racial categorization.
Conservation genetics is an interdisciplinary subfield of population genetics that aims to understand the dynamics of genes in a population for the purpose of natural resource management and extinction prevention. Researchers involved in conservation genetics come from a variety of fields including population genetics, natural resources, molecular ecology, biology, evolutionary biology, and systematics. Genetic diversity is one of the three fundamental measures of biodiversity, so it is an important consideration in the wider field of conservation biology.
"Human Genetic Diversity: Lewontin's Fallacy" is a 2003 paper by A. W. F. Edwards. He criticises an argument first made in Richard Lewontin's 1972 article "The Apportionment of Human Diversity", that the practice of dividing humanity into races is taxonomically invalid because any given individual will often have more in common genetically with members of other population groups than with members of their own. Edwards argued that this does not refute the biological reality of race since genetic analysis can usually make correct inferences about the perceived race of a person from whom a sample is taken, and that the rate of success increases when more genetic loci are examined.
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. Genes and culture continually interact in a feedback loop, changes in genes can lead to changes in culture which can then influence genetic selection, and vice versa. One of the theory's central claims is that culture evolves partly through a Darwinian selection process, which dual inheritance theorists often describe by analogy to genetic evolution.
The Journal of Biological Chemistry (JBC) is a weekly peer-reviewed scientific journal that was established in 1905. Since 1925, it is published by the American Society for Biochemistry and Molecular Biology. It covers research in areas of biochemistry and molecular biology. The editor is Alex Toker. As of January 2021, the journal is fully open access. In press articles are available free on its website immediately after acceptance.
Biocultural anthropology can be defined in numerous ways. It is the scientific exploration of the relationships between human biology and culture. "Instead of looking for the underlying biological roots of human behavior, biocultural anthropology attempts to understand how culture affects our biological capacities and limitations."
The American Journal of Biological Anthropology is a peer-reviewed scientific journal and the official journal of the American Association of Biological Anthropologists. It was established in 1918 by Aleš Hrdlička.
The NAS Award for Scientific Reviewing is awarded by the U.S. National Academy of Sciences (NAS) "to recognize authors whose reviews have synthesized extensive and difficult material, rendering a significant service to science and influencing the course of scientific thought." It has been awarded annually in specific fields since 1979.
Mark Stoneking is a geneticist currently working as the Group Leader of the Max Planck Institute for Evolutionary Anthropology, of Max Planck Gesellschaft at Leipzig, and Honorary Professor of Biological Anthropology, University of Leipzig, Leipzig, Germany. He works in the field of human evolution, especially the genetic evolution, origin and dispersal of modern humans. He, along with his doctoral advisor Allan Wilson and a fellow researcher Rebecca L. Cann, contributed to the Out of Africa Theory in 1987 by introducing the concept of Mitochondrial Eve, a hypothetical common mother of all living humans based on mitochondrial DNA.
The following outline is provided as an overview of and topical guide to evolution:
There are two main approaches currently used to analyze archaeological remains from an evolutionary perspective: evolutionary archaeology and behavioral ecology. The former assumes that cultural change observed in the archaeological record can be best explained by the direct action of natural selection and other Darwinian processes on heritable variation in artifacts and behavior. The latter assumes that cultural and behavioral change results from phenotypic adaptations to varying social and ecological environments.
