Besides reproducibility, you also need to make testable predictions for it to be science. I wonder what would the testable predictions be for most evidence that all (or almost all?) evolution proceeds entirely by random mutation and natural selection. If this isn&#x27;t true then a lot of the stuff in evolutionary psychology and other &quot;just so&quot; explanations may be completely unscientific. Exemplified by crap like this: <a href="https:&#x2F;&#x2F;www.theguardian.com&#x2F;science&#x2F;2007&#x2F;aug&#x2F;25&#x2F;genderissues" rel="nofollow">https:&#x2F;&#x2F;www.theguardian.com&#x2F;science&#x2F;2007&#x2F;aug&#x2F;25&#x2F;genderissues</a>
