Scotland's sheep are shrinking!

Apparently it's a weird side effect of climate change - reverse natural selection.

Normally, the bigger the sheep, the better it will survive a harsh winter.

Except, Scotland's winters aren't that harsh any more. So the sheep don't have to be so big.

I love this quote at the end of the BBC article:

"But it's too early to say if, in 100 years, we will have chihuahuas herding pocket-sized sheep."
