摘要

SIR — Most recently extinct and currently endangered species of birds arc inhabitants of islands, where the effects of anthropogenic predation and habitat modification have been most severe. Recently, palaeontological records have shown that the effect 'of prehistoric humans on insular biotas, particularly in the Pacific, were far more severe than previously believed, and that many extant flighted bird species that now appear to be endemic to single islands were previously more widespread. Here we report that the combination of ancient DNA and palaeontological techniques can provide information necessary for conservation management of such a species, the endangered Laysan duck (Anas laysanensis).
