Evolutionary biology concepts

Ad hoc

Ad hoc is a Latin phrase meaning literally for this.

See Inclusive fitness and Ad hoc

Altruism

Altruism is the principle and practice of concern for the well-being and/or happiness of other humans or animals above oneself.

See Inclusive fitness and Altruism

Behavioral Ecology and Sociobiology

Behavioral Ecology and Sociobiology is a peer-reviewed scientific journal covering quantitative, empirical, and theoretical studies in the field of analysis of animal behavior at the levels of the individual, population, and community.

See Inclusive fitness and Behavioral Ecology and Sociobiology

Belding's ground squirrel

Belding's ground squirrel (Urocitellus beldingi), also called pot gut, sage rat or picket-pin, is a squirrel that lives on mountains in the western United States.

Coefficient of relationship

The coefficient of relationship is a measure of the degree of consanguinity (or biological relationship) between two individuals.

See Inclusive fitness and Coefficient of relationship

Criticism of evolutionary psychology

Evolutionary psychology seeks to identify and understand human psychological traits that have evolved in much the same way as biological traits, through adaptation to environmental cues.

See Inclusive fitness and Criticism of evolutionary psychology

Directional selection

In population genetics, directional selection is a type of natural selection in which one extreme phenotype is favored over both the other extreme and moderate phenotypes.

See Inclusive fitness and Directional selection

E. O. Wilson

Edward Osborne Wilson (June 10, 1929 – December 26, 2021) was an American biologist, naturalist, ecologist, and entomologist known for developing the field of sociobiology.

See Inclusive fitness and E. O. Wilson

Eusociality (Greek εὖ eu "good" and social) is the highest level of organization of sociality.

See Inclusive fitness and Eusociality

Evolutionary biology

Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth.

See Inclusive fitness and Evolutionary biology

Evolutionary invasion analysis

Evolutionary invasion analysis, also known as adaptive dynamics, is a set of mathematical modeling techniques that use differential equations to study the long-term evolution of traits in asexually and sexually reproducing populations.

See Inclusive fitness and Evolutionary invasion analysis

Evolutionary psychology

Evolutionary psychology is a theoretical approach in psychology that examines cognition and behavior from a modern evolutionary perspective.

See Inclusive fitness and Evolutionary psychology

Fisher's geometric model

Fisher's geometric model (FGM) is an evolutionary model of the effect sizes and effect on fitness of spontaneous mutations proposed by Ronald Fisher to explain the distribution of effects of mutations that could contribute to adaptative evolution.

See Inclusive fitness and Fisher's geometric model

Gene-centered view of evolution

The gene-centered view of evolution, gene's eye view, gene selection theory, or selfish gene theory holds that adaptive evolution occurs through the differential survival of competing genes, increasing the allele frequency of those alleles whose phenotypic trait effects successfully promote their own propagation.

See Inclusive fitness and Gene-centered view of evolution

Green-beard effect

The green-beard effect is a thought experiment used in evolutionary biology to explain selective altruism among individuals of a species.

See Inclusive fitness and Green-beard effect

Hamiltonian spite

Within the field of social evolution, Hamiltonian spite is a term for spiteful behaviors occurring among conspecifics that have a cost for the actor and a negative impact upon the recipient.

See Inclusive fitness and Hamiltonian spite

Identity by descent

A DNA segment is identical by state (IBS) in two or more individuals if they have identical nucleotide sequences in this segment.

See Inclusive fitness and Identity by descent

Journal of Evolutionary Biology

The Journal of Evolutionary Biology is a peer-reviewed scientific journal published monthly covering the field of evolutionary biology.

See Inclusive fitness and Journal of Evolutionary Biology

Kin selection

Kin selection is a process whereby natural selection favours a trait due to its positive effects on the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction.

See Inclusive fitness and Kin selection

Martin Nowak

Martin Andreas Nowak (born April 7, 1965) is an Austrian-born professor of mathematics and biology at Harvard University.

See Inclusive fitness and Martin Nowak

Natural selection

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.

See Inclusive fitness and Natural selection

Partial least squares regression

Partial least squares (PLS) regression is a statistical method that bears some relation to principal components regression; instead of finding hyperplanes of maximum variance between the response and independent variables, it finds a linear regression model by projecting the predicted variables and the observable variables to a new space.

See Inclusive fitness and Partial least squares regression

Paul W. Sherman

Paul W. Sherman is a professor Emeritus at Cornell University in animal behaviour best known for his work on the social behavior of rodents (ground squirrels and naked mole rats), eusociality, and evolutionary medicine.

See Inclusive fitness and Paul W. Sherman

Population

Population is the term typically used to refer to the number of people in a single area.

See Inclusive fitness and Population

Price equation

In the theory of evolution and natural selection, the Price equation (also known as Price's equation or Price's theorem) describes how a trait or allele changes in frequency over time.

See Inclusive fitness and Price equation

R/K selection theory

In ecology, selection theory relates to the selection of combinations of traits in an organism that trade off between quantity and quality of offspring. Inclusive fitness and R/K selection theory are evolutionary biology concepts.

See Inclusive fitness and R/K selection theory

Reciprocal altruism

In evolutionary biology, reciprocal altruism is a behaviour whereby an organism acts in a manner that temporarily reduces its fitness while increasing another organism's fitness, with the expectation that the other organism will act in a similar manner at a later time.

See Inclusive fitness and Reciprocal altruism

Reproductive success

Reproductive success is an individual's production of offspring per breeding event or lifetime.

See Inclusive fitness and Reproductive success

Richard Dawkins

Richard Dawkins (born 26 March 1941) is a British evolutionary biologist, zoologist, and author.

Robert Trivers

Robert Ludlow "Bob" Trivers (born February 19, 1943) is an American evolutionary biologist and sociobiologist.

Robin Fox

Robin Fox (born 1934-died 2024) was an Anglo-American anthropologist who wrote on the topics of incest avoidance, marriage systems, human and primate kinship systems, evolutionary anthropology, sociology and the history of ideas in the social sciences.

Ronald Fisher

Sir Ronald Aylmer Fisher (17 February 1890 – 29 July 1962) was a British polymath who was active as a mathematician, statistician, biologist, geneticist, and academic.

Sewall Wright

Sewall Green Wright FRS (For) Honorary FRSE (December 21, 1889March 3, 1988) was an American geneticist known for his influential work on evolutionary theory and also for his work on path analysis.

Shrimp

A shrimp (shrimp (US) or shrimps (UK) is a crustacean (a form of shellfish) with an elongated body and a primarily swimming mode of locomotion – typically belonging to the Caridea or Dendrobranchiata of the order Decapoda, although some crustaceans outside of this order are also referred to as "shrimp".

See Inclusive fitness and Shrimp

Sigmund Freud

Sigmund Freud (born Sigismund Schlomo Freud; 6 May 1856 – 23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for evaluating and treating pathologies seen as originating from conflicts in the psyche, through dialogue between patient and psychoanalyst, and the distinctive theory of mind and human agency derived from it.
