I’m not sure I understand the reasoning.
Are they saying that the initial spread of millet was the sticky variety, and the non-sticky variant was created locally by people favoring bread? Or did the non-sticky variant spread first, and the sticky variant arose later but only replaced the earlier variant where people preferred porridge?
