Biosocial theory is a theory in behavioral and social science that describes personality disorders and mental illnesses and disabilities as biologically-determined personality traits reacting to environmental stimuli. [1] [2] Biosocial theory also explains the shift from evolution to culture when it comes to gender and mate selection.
[2] [3] Sociobiology investigates social behaviors such as mating patterns, territorial fights, pack hunting, and the hive society of social insects. It argues that just as selection pressure led to animals evolving useful ways of interacting with the natural environment, so also it led to the genetic evolution of advantageous social behavior. [4]
The current theory of evolution, the modern evolutionary synthesis (or neo-darwinism), explains that evolution of species occurs through a combination of Darwin's mechanism of natural selection and Gregor Mendel's theory of genetics as the basis for biological inheritance and mathematical population genetics. [80]
[3] [4] There have been a number of different approaches to the study of cultural evolution, including dual inheritance theory, sociocultural evolution, memetics, cultural evolutionism, and other variants on cultural selection theory. The approaches differ not just in the history of their development and discipline of origin but in how they ...
Evolutionary epistemology of theories assumes that scientific theories develop through variation and selection; Memetics is a theory of the variation, transmission, and selection of cultural items, such as ideas, fashions, and traditions; Dual inheritance theory a framework for cultural evolution developed largely independently of memetics
Professor of biology Jerry Coyne sums up biological evolution succinctly: [3]. Life on Earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.
While EDP theory generally aligns with that of mainstream EP, it is distinguished by a conscious effort to reconcile theories of both evolution and development. [5] EDP theory diverges from mainstream evolutionary psychology in both the degree of importance placed on the environment in influencing behavior, and in how evolution has shaped the ...
The theory of evolution by natural selection has also been adopted as a foundation for various ethical and social systems, such as social Darwinism, an idea that preceded the publication of The Origin of Species, popular in the 19th century, which holds that "the survival of the fittest" (a phrase coined in 1851 by Herbert Spencer, [1] 8 years before Darwin published his theory of evolution ...
