When researchers sequenced the extinct predator’s genome, they found it wasn’t a wolf at all but instead a distinct lineage that split off from the rest of the canines some 5.7 million years ago, reports James Gorman for the New York Times. To reveal the dire wolf’s true evolutionary identity, researchers extracted DNA from five fossils between 13,000 and 50,000 years old and sequenced their genomes. The team ultimately recovered around a quarter of the nuclear genome and a full complement of mitochondrial DNA from the samples... Though the bones of the dire wolf are so similar to today’s gray...
