I'm referring of course to Maize, Wheat, and Rice. What is it about this family that was so appealing for those picking out a plant to domesticate? Its not like they were in contact with each other and oculd be like "Yo, I picked Wheat and it rocks, you should pick Maize, its in the same family so I bet it'll be real good too" Esp considering I hear stories about how original wild maize had cobs no bigger than a finger, and it was only through the magic of selectively breeding that they became vast and bulbous like they are today.
