A. Social Darwinism
A quote I found sums this question up, but it'd be better to do some side research.
-
"<span>the theory that individuals, groups, and peoples are subject to the same Darwinian laws of natural selection as plants and animals. Now largely discredited, social Darwinism was advocated by Herbert Spencer and others in the late 19th and early 20th centuries and was used to justify political conservatism, imperialism, and racism and to discourage intervention and reform."</span>
Both Copernicus and Galileo supported the theory of a heliocentric solar system. That means they thought the sun was the center of the solar sytem and all planets revolved around it, while everyone else beleived the Earth was the center of the solar system (geocentric solar system). Both were punished for their views.
