Description: <jats:title>Going Multicellular</jats:title> <jats:p> The volvocine algae include both the unicellular <jats:italic>Chlamydomonas</jats:italic> and the multicellular <jats:italic>Volvox</jats:italic> , which diverged from one another 50 to 200 million years ago. <jats:bold> Prochnik <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="5988" page="223" related-article-type="in-this-issue" vol="329" xlink:href="10.1126/science.1188800">223</jats:related-article> ) compared the <jats:italic>Volvox</jats:italic> genome with that of <jats:italic>Chlamydomonas</jats:italic> to identify any genomic innovations that might have been associated with the transition to multicellularity. Size changes were observed in several protein families in <jats:italic>Volvox</jats:italic> , but, overall, the <jats:italic>Volvox</jats:italic> genome and predicted proteome were highly similar to those of <jats:italic>Chlamydomonas</jats:italic> . Thus, biological complexity can arise without major changes in genome content or protein domains. </jats:p>
