<jats:list-item><jats:p>Common garden experiments are precious to study adaptive phenomenon and adaptive potential, in that they allow to study local adaptation without the confounding effect of phenotypic plasticity. The <jats:italic>Q</jats:italic><jats:sub>ST</jats:sub> − <jats:italic>F</jats:italic><jats:sub>ST</jats:sub> comparison framework, comparing genetic differentiation at the phenotypic and molecular level, is the usual way to test and measure whether local adaptation influences phenotypic divergence between populations.</jats:p></jats:list-item>
<jats:list-item><jats:p>Here, we highlight that the assumptions behind the expected equality <jats:italic>Q</jats:italic><jats:sub>ST</jats:sub> = <jats:italic>F</jats:italic><jats:sub>ST</jats:sub> under neutrality correspond to a very simple model of population genetics. While the equality might, on average, be robust to violation of such assumptions, more complex population structure can generate strong evolutionary noise.</jats:p></jats:list-item>
<jats:list-item><jats:p><jats:italic>Synthesis</jats:italic>. We highlight recent methodological developments aimed at overcoming this issue and at providing a more general framework to detect local adaptation, using less restrictive assumptions. We invite empiricists to look into these methods and theorists to continue developing even more general methods.</jats:p></jats:list-item>
