O is for Opposable Thumbs
IT seems that without fully opposable thumbs, the human race might today be swinging about in trees rather than sitting at laptops writing blogs about cats - what a cat-astrophe that would be.

And, say the scientists, this led to more human co-operation and the development of language.
