Figure 8

Schematic representation of the proposed evolutionary history of the tubercle bacilli according to the presence and absence of the 12/40 polymorphism. The scenario was constructed from the distribution of the 12/40 polymorphism within and between species. This scenario fits in with previously-proposed evolutionary schemes based on deletion regions and single nucleotide polymorphisms [15, 15, 19]
