Final answer:
Robert Braidwood found the late emergence of portable pottery in Jarmo interesting due to possible cultural, technological, economic, or environmental factors. Pottery may have been delayed due to alternative container preferences or until societal changes made it beneficial, and environmental or technological conditions allowed for its creation.
Step-by-step explanation:
Robert Braidwood found it interesting that portable pottery did not appear until late in the life of Jarmo due to the reasons found in archaeological studies. This delay may highlight certain cultural preferences, technological limitations, economic factors, or environmental constraints. In Jarmo, pottery might have been introduced later than in other civilizations due to a variety of these factors, which shaped the development of this technology.
For example, cultural preferences might have emphasized other forms of containers, or there may have been a lack of need for portable pottery until certain social and economic structures, such as agriculture and trade, developed to a point where pottery became advantageous.
Moreover, environmental factors such as the availability of suitable clay or the ability to produce high temperatures for kilns could have played a role in the timing of pottery's appearance. With technological advancements, pottery techniques evolved from simple coil pots tempered in open fires to more sophisticated methods involving potters' wheels and kilns, as seen in other cultures like the Longshan.
