On a remote Scottish island scientists have discovered that the local sheep is actually getting smaller. The ecosystem on this island has been under surveillance since 1985 because of its uniqueness. It is very simple, mainly consisting of sheep and the vegetation they eat.

Now scientists have discovered that the weight of the sheep has decreased 5% over the last 25 years. The scientists claim that warmer climate has made it easier for the sheep thus helping the smaller sheep surviving. Earlier only the larger sheep were able to handle the harsh climate at the island. The reason for this development is earlier springs and longer falls which make the winters shorter.
