<jats:title>Variation on a Theme</jats:title> <jats:p> Given the incredible diversity and complexity in social behavior and ecology that exists across animal taxa, revealing the evolution of neural mechanisms for behavior is a great challenge. <jats:bold>O'Connell and Hofmann</jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="1154" related-article-type="in-this-issue" vol="336" xlink:href="10.1126/science.1218889">1154</jats:related-article> ) examined the expression profiles of several genes involved in the social behavior network and the mesolimbic reward system in 88 species across five vertebrate lineages. A remarkable level of conservation was observed in brain regions linked to social behavior and decision-making, but flexibility seems to have been maintained through variability in neuroendocrine ligand expression across the brain. </jats:p>
