Question 72

- (Topic 3)
The highly dispersed nature of Panzaleo pottery throughout present-day Ecuador has led archaeologists to speculate about the pottery's origins and significance. Jijon y Caamano attributed the pottery's distribution to trade, and based on the large quantities of pottery recovered in the Ambato-Latacunga region of the central Ecuadorian highlands, he proposed that region as the probable locus of production. However. Porras suggests that inhabitants of the subtropical eastern Andean slopes, or montaria. were the original producers of Panzaleo. Ponas" theory involves the forced migration of the montaria population from then homeland in the Quijos River valley into the Ecuadorian highlands. The gradual exodus and ensuing dispersal of the makers of this ware could account for the diffuse distribution of the materials.

A. This distribution is not primarily the result of the relocation of the original makers of the pottery

C. This distribution could not have occurred without the forced migration of certain peoples
