The ideas of social Darwinism have their origins in Darwin’s evolutionary teachings, which placed natural selection and the struggle for survival at the core of development.
According to social Darwinism, the same forms of interaction exist in interpersonal relationships. This perspective encourages biological competition between people and the notion that some communities are stronger and more adaptable than others; these thoughts border on racism. A consequence of social Darwinism was the emergence of eugenics, the pseudo-science of selecting human individuals to create a better sort of human being.
Eugenics is divided into two approaches, namely positive and negative eugenics. Positive eugenics selects and preserves individuals with good traits to create a perfect sample. In contrast, negative eugenics seeks to weed out people with undesirable, unnecessary characteristics to isolate them from society.
