Well, to answer the slightly easier question first, about 10,000 years ago, I would say, is the beginning of this process in the ancient Near East, known as the Fertile Crescent.
For nu at starte med det lettere spørgsmål først, vil jeg sige, at processen begyndte for ca. 10.000 år siden. I den gamle nære orient, kendt som den Frugtbare Halvmåne.
