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.
Darwin proposed pangenesis theory to complement his 1859 theory of evolution via natural selection. Darwin coined the term pangenesis, with pan- meaning whole, and genesis indicating origin. With the term pangenesis, Darwin suggested that all parts of the parents could contribute to the evolution and development of the offspring.
