Since Darwin proposed the theory of evolution by natural selection, there has been no end to the number of thinkers who have applied the theory to their social environment. Today we hear about the theory of evolution guiding insights into such diverse fields as medicine and nutrition to dating advice and even moral philosophy. The fallacy of the appeal to nature seems to stand as a conceptual barrier to some of the more ambitious applications of evolution to other fields. The appeal to nature, in short, states that a proposition or behaviour cannot be evaluated based on its existence in nature alone, because nature provides good and bad and forces us to choose between them by other means. This objection can be fatal in fields such as evolutionary ethics, but seems out of place as a criticism of the paleolithic diet, for example. Below is a list of statements relating evolution to other fields in order of my immediate perception of their plausibility, from lowest to highest. Evolutionary biology can help us define right and wrong. Evolution can define the meaning and purpose of human lives. Evolution can help design better social arrangements and family structures. Evolution proves religion to be false and unnecessary. Evolution can explain human psychology. Evolution produces immutable gender roles. Evolution can tell us how to treat our bodies, including what we should consume. Evolution can inform valuable medical insights. Evolution contributes to the understanding of human history in an important way. What say you - where do you agree or disagree? Is evolutionary biology informative in some places but not others? Is it a non-starter in any field other than biology? Is it a "universal acid that eats through just about every traditional concept and leaves in its wake a revolutionized worldview?" Discuss.
