In biology, evolution is the change in heritable characteristics of biological populations over successive generations. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation.
Dialectical materialism is a materialist theory based upon the writings of Karl Marx and Friedrich Engels that has found widespread applications in a variety of philosophical disciplines ranging from philosophy of history to philosophy of science. As a materialist philosophy, Marxist dialectics emphasizes the importance of real-world conditions and the presence of functional contradictions within and among social relations, which derive from, but are not limited to the contradictions that occur in social class, labour economics, and socioeconomic interactions.
Cultural assimilation is the process in which a minority group or culture comes to resemble a society's majority group or assimilate the values, behaviors, and beliefs of another group whether fully or partially. The different types of cultural assimilation include full assimilation and forced assimilation. Full assimilation is the more prevalent of the two, as it occurs spontaneously. When used as a political ideology, assimilationism refers to governmental policies of deliberately assimilating ethnic groups into the national culture.
Identity formation, also called identity development or identity construction, is a complex process in which humans develop a clear and unique view of themselves and of their identity. Self-concept, personality development, and values are all closely related to identity formation. Individuation is also a critical part of identity formation. Continuity and inner unity are healthy identity formation, while a disruption in either could be viewed and labeled as abnormal development; certain situations, like childhood trauma, can contribute to abnormal development.
Theistic evolution (also known as theistic evolutionism or God-guided evolution) is a view that God acts and creates through laws of nature. It posits that the concept of God is compatible with the findings of modern science, including evolution. Theistic evolution is not in itself a scientific theory, but includes a range of views about how science relates to religious beliefs and the extent to which God intervenes. It rejects the strict creationist doctrines of special creation, but can include beliefs such as creation of the human soul.
