Evolution has nothing to do with morality. Science simply describes what is, not what ought to be. Social Darwinism and eugenics are misapplications of science. We have evolved the capacity for higher reasoning, and so we can develop ethical and moral systems to suit us, rather than following the principle of ‘survival of the fittest’. [1]  Social studies indicate that secularised societies in which evolutionary science is widely accepted enjoy lower rates of societal dysfunction, whereas the USA, which is much more religious and anti-evolution, has worse social health. [2]  Morality may have an evolutionary basis. People who look after their relatives, those who share many of their genes, are maximising the likelihood those genes will be passed on. Altruism benefits the survival of the group as a whole.  [1] ‘Evolution is the foundation of an immoral worldview’, Talk.Origins,  Accessed 3/6/2011  [2] Gregory S.
