Welsh sheep 'more clever than thought'

Sheep aren't viewed as the cleverest of creatures, but new research has found they might be a lot more intelligent than previously thought.

Scientists at the University of Cambridge found that Welsh mountain sheep can map their surroundings, and may even be able to plan ahead.

The discovery shows they have the brainpower to equal rodents, monkeys and, in some tests, even humans.
