Mitochondrial DNA from Myotragus balearicus, an extinct bovid from the Balearic Islands
DNA was extracted from teeth and bones of Myotragus balearicus, a bovid that evolved in isolation on the Balearic Islands (Western Mediterranean) from the end of the Miocene, becoming extinct 4,000 years BP, after the arrival of humans in the islands. The numerous morphological apomorphies of Myotra...
