The major difference between Charles Darwin and Herbert Spencer’s theory of evolution was based on misapplying Darwin’s biological evolutionary concept by political, economical and social-based concepts.
ex
Charles Darwin was an important person in history who wrote: “On the Origin of Species”. In this work, he summed up both history and science. He explained that human evolution is based on natural selection (Organisms develop as new species by spontaneous mutations such as reproductions, having offspring, battling for foods with other organisms and avoid being killed.)
Social Darwinists used Darwin’s idea and made their own ideologies. That the biological world got developed socially and economically. Herbert Spencer, one of the Social Darwinism follower coined the term “survival of the fittest”. He expressed that the world only contains two divisions: rich and poor.
The rich were naturally fittest to survive, and the poor were weak and unfit. Also, they believed it was an error if the poor allowed to continue breeding.
