Answer:
Mitochondrial DNA would probably be the most useful technique in sorting out the evolutionary relationships among these closely related species.
Step-by-step explanation:
Filogeography studies the principles and processes in the geographic distribution of a phylogeny through an intraspecific genetic level. There are different molecular techniques used to sort out the evolutionary relationships among closely related species. Sequencing mitochondrial DNA would probably be most useful in the exposed example. This sequencing is the best among the other because it provides information about uniparental transmission, it does not present recombination and has a mutational rate that feets studies in an intraspecific molecular level.
