The title is click baity, here is the paragraph answering the question:
> This is precisely what happened in the early to mid-20th century. Panama disease, a wilt-causing fungus, evolved to attack one Gros Michel banana tree. It was then able to infect all the Gros Michel banana trees which were planted in close quarters with one another on these massive banana plantations. Only by switching the crop to a new banana that American consumers would like [-Cavendish] —one that was similar to the Gros Michel in color and shape, but was genetically distinct from it—could the banana industry save itself from collapsing. In the process, though, we lost the better banana.
