Appendix 1—table 4. Summary statistics on mutation and recombination for each of the six species.

For each species, the table shows the SNP rate (SNPs per alignment column) $M/L$, the lower bound on the number of phylogeny changes C, and the lower bound on the ratio of phylogeny changes to mutations $C/M$.

Species	SNP rate $M\mathrm{/}L$	Phyl. changes C	$C/M$
Escherichia coli	0.101	43,575	0.156
Bacillus subtilis	0.113	40,811	0.155
Helicobacter pylori	0.202	50,743	0.295
Mycobacterium tuberculosis	0.002	755	0.078
Salmonella enterica	0.085	31,598	0.131
Staphylococcus aureus	0.053	13,215	0.124
