  • Lateral transfer • Many lines of evidence suggest it is important in adaptations in microbes – E.g., K12 vs. O157:H7 – e.g., Many genes show anomalous patterns • However, does not appear to wipe out phylogenetic signal – Core of genomes gives similar phylogeny – Most acquired genes do not last long in lineages – Many claims of LGT are more “identification of anomalies” than detecting LGT Saturday, April 24, 2010
