It&#8217;s a paper which caught my attention for several reasons. First, I&#8217;ve exhibited <a href=\"http:\/\/blogs.discovermagazine.com\/gnxp\/2011\/07\/to-the-antipode-of-asia\/\">some curiosity about the history and prehistory of Southeast Asia of late<\/a>. Elucidating this region&#8217;s historical dynamics may bear upon more general questions of human evolutionary and cultural process. Second, <em>H. pylori<\/em> is a fascinating organism whose connection to specific human populations is tight enough that it can shed light on past interactions of different groups. In short, just like humans  <em>H. pylori<\/em> exhibits regional specificity and local history. But additionally,  <em>H. pylori<\/em> is also subject to natural selection after introduction into a new population, and so can serve as a window upon cultural contacts which might otherwise leave a light demographic footprint.
