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
Animal coloration back with seaweed, sponges and stones. In variable protective resemblance, an animal such as a chameleon, flatfish, squid or octopus changes its skin pattern and colour using special chromatophore cells to resemble whatever background it is currently resting on (as well as for signalling). The main mechanisms to create the resemblances described by Poulton – whether in nature or in military applications – are crypsis, blending into the background so as to become hard to see (this covers both special and general resemblance); disruptive patterning, using colour and pattern to break up the animal's outline, which relates mainly to general
