Explain in detail who could be considered "civilized" and "uncivilized" according the theory of social darwinism.?

Social Darwinism applies Darwin's evolutionary concepts of natural selection and survival of the fittest to human society. One of the main ideas used to measure society in these terms, is the idea of civilization as a scale.

According to Darwin "the grade of civilization seems a most important element in the success of nations". To him, progress only went one way, and it was European's society's way as the example of what's civilized. Any society that didn't move along with Europe's perspective on moral and intellectual values, manifestations of technological or political advancement, would be considered "savage" or "uncivilized".

Hope this helps!
