From Parasite to Mutualist: Rapid Evolution of Wolbachia in Natural Populations of Drosophila

Andrew R. Weeks, Michael Turelli, William R. Harcombe, K. Tracy Reynolds, Ary A. Hoffman, PLOS Biology

This is a research paper on a case study in Wolbachia evolution published in PLoS Biology in 2007. The study takes advantage of a natural experiment - the spread of Wolbachia through California Drosophila populations - to test the hypothesis that maternal transmission favors evolution towards mutualism. This paper provides insight into Wolbachia biology, but also a case study for a broader evolutionary principle.
