显示更多 [+] 显示较少 [-]After visiting the Falkland Islands during the voyage of the Beagle, Charles Darwin remarked on the surprising presence of a wolf-like canid unique to the islands [1]. One hundred and forty years after its extinction [2], the evolutionary relationships of this unusual canid remain unresolved. Here, we present a phylogenetic analysis based on nuclear and mtDNA sequence data from the extinct Falklands wolf and find that its closest extant relative is the South American maned wolf. Molecular dating analyses suggest that the Falklands wolf and several extant South American canid lineages likely evolved in North America, prior to the Great American Interchange. The Falklands wolf was the sole representative of a distinct South American canid lineage that survived the end-Pleistocene extinctions on an island refuge. © 2009 Elsevier Ltd. All rights reserved.
