Social Darwinism, the theory that persons, groups, and races are subject to the same laws of natural selection as Charles Darwin had perceived in plants and animals in nature.
While Darwin coined the term struggle for survival, it was Herbert Spencer (1820-1903) who invented and popularized the concept of survival of the fittest, and Spencer is widely considered the chief proponent of social Darwinism.
