there's evidence of hominid occupation in the british isles as early as
400,000 years ago, in the time period between ice ages.  but we have no way
of knowing what food was native to britain at that time, or even if we knew
what the climate was and what was growing, do we know that humans actually
ate it?  or do we ever really *know* what part of the world our remote
ancestors lived in?  humans have been migrating around the earth for
countless millenia, and most likely interbreeding along the way.

i'll settle for _Naked with a sharp stick_
