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 ...
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 ...
Therefore, species that form groups through social interaction will result in a group of individuals that gain an evolutionary advantage, such as increased protection against predators, access to potential mates, increased foraging efficiency and the access to social information. Important aspects of group living include the frequency and type ...
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.

Man is a species-being, not only because he practically and theoretically makes the species – both his own and those of other things – his object, but also – and this is simply another way of saying the same thing – because he looks upon himself as the present, living species, because he looks upon himself as a universal and therefore ...
The change in brain size may have been the result of a dietary shift—towards higher quality and difficult to obtain food sources [36] —or may have been driven by the social requirements of group living, which promoted sharing and provisioning. [8] Recent authors, such as Kaplan, argue that both aspects are probably important. [36]
Unilineal evolution, also referred to as classical social evolution, is a 19th-century social theory about the evolution of societies and cultures.It was composed of many competing theories by various anthropologists and sociologists, who believed that Western culture is the contemporary pinnacle of social evolution.
However, natural selection remained controversial as a mechanism, partly because it was perceived to be too weak to explain the range of observed characteristics of living organisms, and partly because even supporters of evolution balked at its "unguided" and non-progressive nature, [29] a response that has been characterised as the single most ...
