| ancient mitochondrial genome reveals unsuspected taxonomic affinity of the extinct chatham duck (pachyanas chathamica) and resolves divergence times for new zealand and sub-antarctic brown teals. | the chatham duck (pachyanas chathamica) represented one of just three modern bird genera endemic to the chatham archipelago (situated ~850 km east of new zealand) but became extinct soon after humans first settled the islands (c. 13th-15th centuries ad). the taxonomic affinity of the chatham duck remains largely unresolved; previous studies have tentatively suggested placements within both tadornini (shelducks) and anatini (dabbling ducks). herein, we sequence a partial mitochondrial genome (exc ... | 2014 | 23994164 |
