(You may or may not have seen this figure in a previous question in this exam.) In the tree, the M. tuberculosis lineages that are currently circulating in humans are indicated in color and are named L1 to L7. The pie charts on the world map indicate for each of these lineages where they occur. In the phylogenetic tree, names of Mycobacterium (M.) strains derived from non-human animals and from an ancient Peruvian mummy are written in full and are not colored. Which of the following statements is correct? The L4 lineage is more closely related to the L3 lineage than to the L2 lineage Human M. tuberculosis lineages form a monophyletic group of which all members only infect humans Mycobacterium strains found in non-human animals form a monophyletic group of which all members only infect non-human animals M. tuberculosis is paraphyletic in humans
