An interesting article that seems to overturn everything we've been taught about the horrible plagues that took over 100 million lives during the Dark Ages. Read the story @ http://blogs.discovermagazine.com/d...xonerates-rats-as-the-bearers-of-black-death/
it doesn't exactly exonerate rats and fleas... which did perpetuate the disease spread.... it just says the disease mutated to also spread by coughing..... which makes sense.
