Molecular Biology and Evolutionby Oxford University Press, sheds light on the evolution of North American wolves, a topic that has sparked controversy among both conservationists and taxonomists.
The origins and genetic ties of the wolves and coyotes residing in southeastern Canada have been a long-standing mystery for scientists. Eastern wolves, in particular, have been the center of much debate, with their classification as a distinctstill being uncertain as they may have arisen from the hybridization of grey wolves and coyotes.
In Canada, the eastern wolf has been recognized by some as a distinct species based on genetic and behavioral studies. Eastern wolves are listed as “Special Concern” in Canada under the federal Species at Risk Act and “Threatened” in Ontario under the provincial Endangered Species Act.
To test hypotheses related to these competing findings for eastern wolves, researchers sequenced whole genomes of 25 animals of known origin and levels of contemporary hybridization, representative of all Canadian wolf-like canid types. The analysis shows that eastern wolves that inhabit the Great Lakes region in southeastern Canada are genetically distinct from other canids in the region.
“This manuscript addresses key evolutionary questions among North American wolf-like canids, but also provides data of direct and applied relevance,” said the paper’s lead author, Christopher Kyle.
