Final answer:
AMS (Accelerator Mass Spectrometry) dating at Guila Naquitz, an archaeological site in Mexico, has been instrumental in determining the age of plant domestication in the region, providing deep insights into ancient agricultural practices.
Step-by-step explanation:
The phrase 'Guila Naquitz' refers to an archaeological site in Mexico, known for its significance in the study of ancient human activities. The question seems to pertain to AMS dating, which stands for Accelerator Mass Spectrometry dating, a form of radiocarbon dating that is used to determine the age of archaeological samples with high precision. At the Guila Naquitz cave, AMS dating has been crucial in establishing the timeline of the early domestication of plants in Mesoamerica, particularly squash. Researchers have dated seeds and other organic material found at the site, providing insights into the agricultural practices of the people who lived there thousands of years ago.
