Unlike crown eukaryotic species, microbial species are created by continual processes of gene loss and acquisition promoted by horizontal genetic transfer. The amounts of foreign DNA in bacterial genomes, and the rate at which this is acquired, are consistent with gene transfer as the primary catalyst for microbial differentiation. However, the rate of successful gene transfer varies among bacterial lineages. The heterogeneity in foreign DNA content is directly correlated with amount of genetic… CONTINUE READING
