Supplementary material from "First monk seal from the Southern Hemisphere rewrites the evolutionary history of true seals"
Living true seals (phocids) are the most widely dispersed semi-aquatic marine mammals, and comprise geographically separate northern (phocine) and southern (monachine) groups. Both are thought to have evolved in the North Atlantic, with only two monachine lineages—elephant seals and lobodontins—subs...
