This work is supported by the Natural Sciences and Engineering Research Council of Canada (NSERC) Discovery Program and the Canadian Institutes of Health Research (team grant on Intestinal Microbiomics, Institute of Nutrition, Metabolism and Diabetes).

A likely major contributor is illegitimate recombination, or recombination between short conserved sequences (a few bases), coupled with functional selection of genes [30].

Bacteriophages offer a special perspective on the diversity, origins, and evolution of viruses, not only in their tremendous abundance there are more than 1031 phage particles in the biosphere but in their distant origins, likely more than three billion years ago [1,2]. Genetic exchange events giving rise to genome mosaicism are usually only observed at the nucleotide sequence level when the events have occurred relatively recently in evolutionary time. USA 110, 1077110776 (2013). Furthermore, phage-encoded homologous recombinases have properties that are well-suited to facilitating this process [31]. J. Virol. T2 is a 'tailed phage', [1] one of a group known as the 'T4-like viruses'. With high throughput sequencing approaches becoming generally and relatively cheaply available, it has become possible to sample substantial numbers of metagenomic samples and to compare viral populations as a functions of geography and time, providing considerable insights into the dynamics of phage populations [6,7].
