english: One of the most difficult things to keep in mind about evolution is that when we say things like, "Genes want to make more copies of themselves," or even, "natural selection," we're actually using metaphors.
non_english: Treba imati na umu da kada kažemo stvari poput: "Geni žele da naprave što više svojih kopija" ili "prirodna selekcija", mi, u stvari, koristimo metafore.
