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 ...
Many anthropologists and social theorists now consider unilineal cultural and social evolution a Western myth seldom based on solid empirical grounds. Critical theorists argue that notions of social evolution are simply justifications for power by the élites of society. Finally, the devastating World Wars that occurred between 1914 and 1945 ...

Evolution is the principal scientific theory that biologists use to understand life and is used in many disciplines, including medicine, psychology, conservation biology, anthropology, forensics, agriculture and other social-cultural applications.
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.
Social evolution: ant societies have evolved elaborate caste structures, in this species, Atta cephalotes, widely different in size and function. The section summarizes the concepts of population genetics, a branch of evolutionary theory combining Mendelian genetics and natural selection in mathematical form to explain the pressures on animal societies.
The theory of evolution, as described in Darwin's The Origin of Species, provided for many social theorists the necessary scientific foundation for the idea of social and political progress. The terms evolution and progress were in fact often used interchangeably in the 19th century.
