    Molecular dating of caprines using ancient DNA sequences of <it>Myotragus balearicus</it>, an extinct endemic Balearic mammal by Alcover Josep Antoni, Marquès-Bonet Tomàs, Sampietro Lourdes, Castresana Jose, Lalueza-Fox Carles, Bertranpetit Jaume

    Published 2005-12-01
    “…Using the calibration provided by the isolation of Balearic Islands, we calculated that the initial radiation of caprines can be dated at 6.2 ± 0.4 Mya. In addition, alpine and southern chamois, considered until recently the same species, split around 1.6 ± 0.3 Mya, indicating that the two chamois species have been separated much longer than previously thought.…”
