... Gene flow across distantly related bacterial groups (horizontal gene transfer) is a major feature of bacterial evolution (Maynard Smith et al, 1991; Campbell, 2000; Ochman et al, 2000; Gogarten et al, 2002). This evolution need not be slow. The intense selection pressure imposed on microbial communi ...
