Comment on "Evidence of prehistoric human activity in the Falkland Islands".

Stable isotopes from archaic Falkland Islands wolves ( Dusicyon australis ) indicate a high trophic, marine diet. Hamley et al. argue that this is consistent with mutualism with Yaghan people. However, most D. australis had similar isotopic signatures in the European era, despite human persecution. These data therefore neither support nor refute human-mediated introduction of D. australis to the Falklands.
