Figure 4.
Neighbour-joining tree of cytochrome b sequences (552 bp) of 19 species of hares, computed using the Kimura two-parameter model of evolution (Kimura 1980) and 1000 bootstrap replicates, using the program MEGA v. 3.1 (Kumar et al. 2004). Sequences from the European rabbit (Oryctolagus cuniculus) and cottontail (Sylvilagus floridanus) were used as outgroups. All sequences were downloaded from GenBank (accession numbers are depicted on the tips of the tree). Species names and specimen locations are also indicated.
