摘要
The origins of jawed vertebrates (gnathostomes) lie somewhere within the ranks of long-extinct jawless fishes, represented today as the lampreys and hagfishes. Recent discoveries of hitherto unknown kinds of jawless fishes (agnathans), together with re-examination of known agnathans and advances in systematic methods, have revitalized debates about the relationships of ancient fishes and given fresh insights into early vertebrate history.
