Description:
Barriers to dispersal between populations allow them to diverge through local adaptation or random genetic drift. High-resolution multilocus sequence analysis revealed that, on a global scale, populations of hyperthermophilic microorganisms are isolated from one another by geographic barriers and have diverged over the course of their recent evolutionary history. The identification of a biogeographic pattern in the archaeon Sulfolobus challenges the current model of microbial biodiversity in which unrestricted dispersal constrains the development of global species richness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitaker, Rachel J -- Grogan, Dennis W -- Taylor, John W -- New York, N.Y. -- Science. 2003 Aug 15;301(5635):976-8.
