A novel taxon selection method, aimed at minimizing recombination, clarifies the discovery of a new sub‐population ofHelicobacter pylorifrom Australia

We present a novel method for taxon selection, the aim being to minimize problems arising from highly recombinant species such as Helicobacter pylori. Helicobacter pylori has accompanied modern-human migration out of Africa and is marked by a phylogeographic strain distribution, which has been exploited to add an extra layer of information about human migrations to that obtained from human sources. However, H. pylori's genome has high sequence...
