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 approach studies the evolution of policy change, [1] including the evolution of conflicts. [2] The theory posits that most social systems exist in an extended period of stasis, which may be punctuated by sudden shifts leading to radical change.
Moreover, they rejected directional change (i.e. orthogenetic, teleological or progressive change). Most archaeologists work within the framework of multilineal evolution. [citation needed] Other contemporary approaches to social change include neoevolutionism, sociobiology, dual inheritance theory, modernisation theory and postindustrial theory.
Rapidly evolving peripherally isolated populations may be the place of origin of many evolutionary novelties. Their isolation and comparatively small size may explain phenomena of rapid evolution and lack of documentation in the fossil record, hitherto puzzling to the palaeontologist.
It is an examination of social change and culture from the perspective of a sociologist. The 25 topics discussed in the work are separated into four topics: social evolution, social trends, short-run changes, and the subjective in the social sciences. [3] This collection of works examines culture and social change in the world.
Work in developmental biology has identified dynamical and physical mechanisms of tissue morphogenesis that may underlie such abrupt morphological transitions. Consequently, consideration of mechanisms of phylogenetic change that are actually (not just apparently) non-gradual is increasingly common in the field of evolutionary developmental biology, particularly in studies of the origin of ...
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. [3]
1. The Annie E. Casey Foundation proposes mapping an organization's social change work along three criteria: Impact, Influence, Leverage. The impact of your work is its program outcomes; Your influence is how much other actors change as a result of your work; Your leverage is how much investment others put into your model. [29]
