Final answer:
An archeologist seeking insight from the living descendants of a society for understanding an artifact's use is practicing ethnoarchaeology. This methodology respects and integrates indigenous knowledge with archaeological analysis for a more accurate understanding of ancient cultures.
Step-by-step explanation:
The method being described where an archeologist consults with the living descendants to understand the use of an ancient artifact is known as ethnoarchaeology. This approach combines ethnographic methods with archaeological analysis to better interpret the archaeological record, particularly the functions and meanings of artifacts. It acknowledges the continuity of cultures and allows archaeologists to draw conclusions about past societies based on knowledge preserved by their descendants.
Combining ethnology with archaeological techniques helps create a more accurate understanding of the past by integrating the direct experiences of people who maintain cultural connections to the artifacts being studied. Moreover, this practice respects the knowledge and authority of Indigenous and local communities regarding their own cultural heritage.
