While there is little doubt that the grey wolf is one of the world's most iconic species, it is equally true that it is one of the world's most reviled. This later sentiment has seen them extirpated from much of their former habitat. However, in a few places, wolves are making a comeback. In this episode, Sarah Hendricks, Dr Rena M. Schweizer and Prof. Robert Wayne discuss their recent research exploring the genetic history of naturally re-established wolf populations in the US states of Oregon and Washington: their discovery that some of these populations represent a genetic mixing of two distinct ecotypes presents challenges for current conservation policy in the country, and raises the question: what wolf belongs where?
