Where did black squirrels come from?
Published in the journal BMC Evolutionary Biology, the research found that the allele, or a variant form of a specific gene, that causes a squirrel to be black did not originate with gray squirrels. It likely resulted from gray squirrels interbreeding with fox squirrels (a species that also has a black morph).
Why did the Victorians introduce grey squirrels?
The spread of grey squirrels in the UK is largely down to the acts of an English duke, new research has claimed. Imperial College London said greys were first imported in the 1890s and it was thought they advanced rapidly as they could adapt well to new habitats.
