relationships of the extinct moa-nalos, flightless hawaiian waterfowl, based on ancient dna.the extinct moa-nalos were very large, flightless waterfowl from the hawaiian islands. we extracted, amplified and sequenced mitochondrial dna from fossil moa-nalo bones to determine their systematic relationships and lend insight into their biogeographical history. the closest living relatives of these massive, goose-like birds are the familiar dabbling ducks (tribe anatini). moa-nalos, however, are not closely related to any one extant species, but represent an ancient lineage that colonized t ...199910649633
