USA HISTORY

Detailed explanation-1: -Social Darwinism is a loose set of ideologies that emerged in the late 1800s in which Charles Darwin’s theory of evolution by natural selection was used to justify certain political, social, or economic views.

Detailed explanation-2: -Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor, which have accumulated gradually over very long time periods.

Detailed explanation-3: -Darwin passionately opposed social injustice and oppression. He would have been dismayed to see the events of generations to come: his name attached to opposing ideologies from Marxism to unbridled capitalism, and to policies from ethnic cleansing to forced sterilization.

Detailed explanation-4: -"Survival of the fittest” is a popular term that refers to the process of natural selection, a mechanism that drives evolutionary change. Natural selection works by giving individuals who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.

Detailed explanation-5: -There are four principles at work in evolution-variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
