 The data indicate that this event occurred not earlier than the last third of the 10th century [BC] and most probably during this time.The coincidence of this event with a major reorganization of the copper industry of the region—attributed to the results of the campaign of Pharaoh Shoshenq I—raises the possibility that the two were connected, and that camels were introduced as part of the efforts to improve efficiency by facilitating trade.Desert tribes and Mongolian nomads use camel hair for tents, yurts, clothing, bedding and accessories.
