Why is yawning contagious?

JohnH asked the Naked Scientists:
   
Why is yawning contagious?   Is this a learned social behaviour or is it a hard-wired biological response?

Thanks!

John from Pittsburgh, Pennsylvania

What do you think?

I haven't read the links, so if I am repeating apologies.

There is a theory that copying a yawn is only done by empathetic people.
