Social evolution may refer to: Social change; Sociocultural evolution, the change of cultures and societies over time; Sociobiology, explaining social behavior in terms of evolution; Cultural evolution, an evolutionary theory of social change; Evolution of eusociality, the evolution of highly cooperative behaviors in animal species
In H. rubicundus, females produce a single brood in cooler regions and two or more broods in warmer regions, so the former populations are solitary while the latter are social. [77] In another species of sweat bees, L. calceatum, social phenotype has been predicted by altitude and micro-habitat composition, with social nests found in warmer ...
Cultural evolution is an evolutionary theory of social change. It follows from the definition of culture as "information capable of affecting individuals' behavior that they acquire from other members of their species through teaching, imitation and other forms of social transmission". [1] Cultural evolution is the change of this information ...
The individuals giving up their own reproductive success form a sterile caste of workers within the group. All species that practice reproductive altruism produce one or more queens, the only breeding females, who are larger than the rest. The remainder of the society is composed of a few breeding males, sterile male and female workers, and the ...
Although presocial species are much more common than eusocial species, eusocial species have disproportionately large populations. [ 6 ] The entomologist Charles D. Michener published a classification system for presociality in 1969, building on the earlier work of Suzanne Batra (who coined the words eusocial and quasisocial in 1966).
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.

Eventually, in the 19th century three major classical theories of social and historical change emerged: sociocultural evolutionism; the social cycle theory; the Marxist theory of historical materialism. These theories had a common factor: they all agreed that the history of humanity is pursuing a certain fixed path, most likely that of social ...
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] 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.
