Bacterial Species Merging

Caption: Helianthus anomalus, a hybrid sunflower species. The authors speculate that in Campylobacter, hybridization took place during colonization of the novel environment of agriculture, while in Helianthus, hybridization facilitated the colonization of a novel sand dune habitat. This image relates to an article that appeared in the April 11, 2008, issue of the journal Science, published by AAAS. The study, by Dr. Samuel K. Sheppard and colleagues at University of Oxford in Oxford, UK, was titled "Convergence of Campylobacter Species: Implications for Bacterial Evolution."
