Myotragus of the island of Majorca ("Myotragus pepgonellae") indicate that "Myotragus balearicus", in spite of being a browsing animal, descended originally from grazers. The closest related species to "Myotragus" are ovine, such as the extinct "Nesogoral" of the Plio-Pleistocene of Sardinia, the old "Gallogoral" of France (possible mainland ancestor of both "Myotragus" and "Nesogoral"), "Ovis" (present sheep and mouflon) and the mountain goats of Central Asia. The last ancestor common to "Myotragus" and "Nesogoral" arrived at Majorca and Sardinia around 6 million years ago, a time at which the Straits of Gibraltar were closed and the Mediterranean Sea was a small
