 
This concept was formulated by a man
called Charles Darwin, who in November 1859 wrote a book called "The origin of the species."
Herbert Spencer condensed Darwin's work into a short phrase  "Survival of the fittest."
On the front cover Darwin added "By means of a natural selection."
Darwin concluded that nature rather than nurture created the superior man.
Darwin's theory became known as Social Darwinism.
Conflict drew support from a virulent form of militarism claimed to be based on biological science
Leading German thinkers argued that war was an evolutionary necessity
a natural outgrowth of the Darwinian struggle for survival
The term 'Social Eugenics' was coined by
Francis Galton, Darwin's cousin in 1883
Eugenics came out of the Greek 'EU'
meaning 'good' or 'well'  and the suffix genes meaning 'born'
Eugenics is a science and
social movement that aims to improve the genetic makeup of the human population
In the early 1900's eugenics was mostly used in social policies
Eugenicists created specific policies that they believed would lead to an improvement in the human gene pool
