The tree was rooted with An. sinensis Wiedemann, 1828 as an outgroup species. The analysis of the tree indicated that Palearctic and Nearctic members of the group represent separate … WebSome trees represent the relationships among major groups of organisms, species, populations, individuals, or even genes. The branches of the tree correspond to ancestor/descendent relationships within a lineage: the part of the branch nearer the base of the tree represents the lineage that is ancestral to the part of the branch nearer the tips.
