Part of why I find this interesting is, being a bean grower, that I feel this is the case with common belief in the origin of Phaseolus vulgaris. The story that it was introduced to Europe from the New World just doesn't make any sense given the ancient story of Jack and the Beanstalk, thousands of years ago. It's one of the oldest written stories in history. Clearly Europe was in possession of very tall plants that grew beans, so how did the story get so convoluted? This documentary explains how these things go wrong with traditional archaeological narrow thinking.
