FIGURE 6.

Evolutionary timetree of Rhizostoma pulmo. The timetree shows the divergence time in a scale of mya. Notice the divergence time of 4.59 million years ago (mya), which separates Israeli R. pulmo samples from the rest. The "Messinian Salinity Crisis" (MSC, dashed gray) and the Zanclean flood (dashed light blue) times estimates are marked. Color represents R. pulmo sampling locations: red—Israel; purple—Italy; blue—western MS; yellow—Tunisia; green—Slovenia. Rhizostoma luteum (gray) was used as an outgroup
