<jats:p>Advances in epigenetics spur modern support for a long-discredited theory of inheritance</jats:p>

<jats:p> Pershing <jats:italic>et al</jats:italic> . ( <jats:italic>Science,</jats:italic> 13 November 2015, p. 809) concluded that recent warming in the Gulf of Maine contributed to the collapse of Gulf of Maine cod. We argue that this conclusion is based on a flawed analysis of the population dynamics of this cod stock. We believe that understanding the potential role of climate change in the collapse of this stock requires more defensible analyses. </jats:p>

<jats:p> Pershing <jats:italic>et al</jats:italic> . (Reports, 13 November, p. 809) concluded that failure to account for temperature in the assessment and management of Gulf of Maine Atlantic cod caused overfishing. We argue that the “extra mortality” calculation driving this conclusion is an artifact. Environmental factors affect all stocks, but attribution of additional mortality to temperature alone by Pershing <jats:italic>et al</jats:italic> . is unsupported by the data. </jats:p>

<jats:p> Palmer <jats:italic>et al</jats:italic> . and Swain <jats:italic>et al</jats:italic> . suggest that our “extra mortality” time series is spurious. In response, we show that including temperature-dependent mortality improves abundance estimates and that warming waters reduce growth rates in Gulf of Maine cod. Far from being spurious, temperature effects on this stock are clear, and continuing to ignore them puts the stock in jeopardy. </jats:p>
