Abstract excerpt
Horizontal gene transfer (HGT) can create diversity in the genetic repertoire of a lineage. Successful gene transfer likely occurs more frequently between more closely related organisms, leading to the formation of higher-level exchange groups that in some respects are comparable to single-species populations. Genes that appear fixed in a single species can be replaced through distant homologs or iso-functional...
