Why are the squirrels black in Canada?

Why are there so many black squirrels?
As a new study published in the journal BMC Evolutionary Biology explains, squirrels sporting black coats owe their distinctive appearance to interbreeding between gray and fox squirrels, which carry a faulty pigment gene known to give some members of the predominantly reddish-brown species darker fur.
