We watched "Walking with Cavemen" last night. (Netflix.)  Very interesting portrayal of early man.  I learned a lot, though I'm not sure how much of the film was fact and how much was speculation.  The climate/food connection was especially interesting to me.  Also, it looks like we were meat eaters for quite some time before we ever cooked our food.  So why do we have so many problems with e-coli and bacteria today?  Any thoughts?
