===Impact on economic and political debates===
While some, like Spencer, used analogy from natural selection as an argument against government intervention in the economy to benefit the poor, others, including [[Alfred Russel Wallace]], argued that action was needed to correct social and economic inequities to level the playing field before natural selection could improve humanity further. Some political commentaries, including [[Walter Bagehot]]'s ''Physics and Politics'' (1872), attempted to extend the idea of natural selection to competition between nations and between human races. Such ideas were incorporated into what was already an ongoing effort by some working in [[anthropology]] to provide scientific evidence for the superiority of [[Caucasian race|Caucasians]] over non-white races and justify European [[imperialism]]. Historians write that most such political and economic commentators had only a superficial understanding of Darwin's scientific theory, and were as strongly influenced by other concepts about social progress and evolution, such as the Lamarckian ideas of Spencer and Haeckel, as they were by Darwin's work. Darwin objected to his ideas being used to justify military aggression and unethical business practices as he believed morality was part of fitness in humans, and he opposed [[polygenism]], the idea that human races were fundamentally distinct and did not share a recent common ancestry.<ref>{{harvnb|Bowler|2003|pp=294–307}}</ref>
