Darwinism sees natural selection as the decisive influence on evolution, health and survival of a species. The logical conclusion is that this natural selection partly no longer applies to humans. This species is increasingly influencing selection by, among other things, all kinds of medical techniques.
Therefore, Darwin's theory is controversial, since the reality is that it does not apply to all species in an absolute way, but depends on external factors that can modify this theory.
In addition, it raises the existence of species that prevail over others through force or supremacy, which leads to the development of dangerously totalitarian theories, such as social Darwinism.
