The iconic, prehistoric dire wolf, which prowled through Los Angeles and elsewhere in the Americas over 11 millennia ago, was a distinct species from the slightly smaller gray wolf, an international team of scientists reports today in the journal
Nature.
The study, which puts to bed a mystery that biologists have pondered for more than 100 years, was led by researchers from UCLA, along with colleagues from Durham University in the U.K., Australia s Adelaide University and Germany s Ludwig Maximilian University.
