<jats:title>An Odd Sort of Revolution</jats:title> <jats:p> Joseph Hooker was the director of the Royal Botanic Gardens at Kew, London, when Charles Darwin and Alfred Wallace were presenting their ideas about evolution by natural selection. Hooker was a good friend of Darwin's and an ardent ally of evolutionary thinking, who came to realize that natural selection would have little impact on the taxonomist's endeavor. <jats:bold>Endersby</jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="1496" related-article-type="in-this-issue" vol="326" xlink:href="10.1126/science.1165915">1496</jats:related-article> ) reviews taxonomic practice in the 19th century, arguing that the concept of evolution was almost a sideshow in the energetic debate about whether to group varieties into single species or whether to divide species into endless varieties. On the one hand, Hooker was a “lumper,” who found it hard to tolerate the thought of species constantly emerging, because it hindered his analysis of global patterns of species richness. On the other hand, Darwin's vision reconciled both modes of classification in revealing the genealogy of life on Earth. </jats:p>

<jats:title>TAL Order</jats:title> <jats:p> <jats:italic>Xanthomonas</jats:italic> bacteria attack their plant hosts by delivering their own transcription-activator–like (TAL) proteins into the plant cell nucleus and alter the plant's gene regulation (see the Perspective by <jats:bold> <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="5959" page="1491" related-article-type="in-this-issue" vol="326" xlink:href="10.1126/science.1183604"> <jats:bold>Voytas and Joung</jats:bold> </jats:related-article> </jats:bold> ). <jats:bold>Moscou and Bogdanove</jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="1501" related-article-type="in-this-issue" vol="326" xlink:href="10.1126/science.1178817">1501</jats:related-article> , published online 29 October: see the cover) and <jats:bold> Boch <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="1509" related-article-type="in-this-issue" vol="326" xlink:href="10.1126/science.1178811">1509</jats:related-article> , published online 29 October) have now discovered how the similar but not identical repeats in the TAL proteins encode the specificity needed for the proteins to find their targets. Each repeat is specific for one DNA base pair, a specificity encoded by hypervariable amino acid positions. Combining several repeats with different amino acids in the hypervariable positions allowed the production of new effectors that targeted new DNA sites. </jats:p>
