BTW, speaking of "Walking with Cavemen," if anyone gets the chance to see 
a similar program called "The Rise of Man," I'd highly recommend it. In 
terms of diet they are a lot more explicit about stating that we evolved 
consuming a higher percentage of dietary fat as well as the fats' 
importance to our evolution. They don't go into great detail with this, 
but it's still discussed more than a lot of the show's predecessors. The 
show is also a pretty engaging one as well!
