I, Brian

It's a theory that's been gaining ground for some time. I think the Apollo missions essentially first addressed it, so it's not a new theory.

However, I'm sure New Scientist mentioned not long ago something about a great disparity of certain isotope distributions across the earth, the moon, mars, and different forms of meteorite. You can be assured that this entire issue has not yet been satisfactorily addressed.
