<p><span>Hamilton and Miller (</span><a class="link__reference js-link__reference" title="Link to bibliographic citation" rel="references:#cobi12678-bib-0014" href="http://onlinelibrary.wiley.com/doi/10.1111/cobi.12678/full#cobi12678-bib-0014">2016</a><span>) provide an interesting and provocative discussion of how hybridization and introgression can promote evolutionary potential in the face of climate change. They argue that hybridization—mating between individuals from genetically distinct populations—can alleviate inbreeding depression and promote adaptive introgression and evolutionary rescue. We agree that deliberate intraspecific hybridization (mating between individuals of the same species) is an underused management tool for increasing fitness in inbred populations (i.e., genetic rescue; Frankham </span><a class="link__reference js-link__reference" title="Link to bibliographic citation" rel="references:#cobi12678-bib-0008" href="http://onlinelibrary.wiley.com/doi/10.1111/cobi.12678/full#cobi12678-bib-0008">2015</a><span>; Whiteley et al. </span><a class="link__reference js-link__reference" title="Link to bibliographic citation" rel="references:#cobi12678-bib-0030" href="http://onlinelibrary.wiley.com/doi/10.1111/cobi.12678/full#cobi12678-bib-0030">2015</a><span>). The potential risks and benefits of assisted gene flow have been discussed in the literature, and an emerging consensus suggests that mating between populations isolated for approximately 50–100 generations can benefit fitness, often with a minor risk of outbreeding depression (Frankham et al. </span><a class="link__reference js-link__reference" title="Link to bibliographic citation" rel="references:#cobi12678-bib-0009" href="http://onlinelibrary.wiley.com/doi/10.1111/cobi.12678/full#cobi12678-bib-0009">2011</a><span>; Aitken & Whitlock </span><a class="link__reference js-link__reference" title="Link to bibliographic citation" rel="references:#cobi12678-bib-0001" href="http://onlinelibrary.wiley.com/doi/10.1111/cobi.12678/full#cobi12678-bib-0001">2013</a><span>; Allendorf et al. </span><a class="link__reference js-link__reference" title="Link to bibliographic citation" rel="references:#cobi12678-bib-0002" href="http://onlinelibrary.wiley.com/doi/10.1111/cobi.12678/full#cobi12678-bib-0002">2013</a><span>).</span></p>
