Location: Oaxaca Valley, Mexico View
Guilá Naquitz Cave is an archaeological site located in the Oaxaca Valley in southern Mexico. The name “Guilá Naquitz” translates to “White Cliff” in the Zapotec language. This site is highly significant for its evidence of some of the earliest domestication of plants in the Americas, specifically maize and squash. It offers key insights into the transition of human societies from foraging to agriculture in Mesoamerica.
Excavations and Discoveries
Time Period
- The site dates back approximately 10,000 to 8,000 years ago (circa 8000–6000 BCE).
- Evidence suggests that the cave was seasonally inhabited by small groups of hunter-gatherers.
Major Discoveries
- Domesticated Plant Remains:
- Cucurbita (squash): Excavators discovered early remains of domesticated squash seeds, dates back 8,000–10,750 years BP. These are some of the earliest known examples of plant domestication in the Americas.
- Maize: The site contains early traces of maize (corn), suggesting experimentation with cultivating wild grasses that eventually led to domesticated maize.
- Stone Tools: A wide variety of stone tools were discovered, including scrapers, grinding stones (metates and manos), and blades. These tools were likely used for processing seeds and other food sources.
- Food Storage: Evidence suggests that the inhabitants stored food, particularly squash, which indicates a shift towards planned food production and storage.
The domestication of Cucurbita (squash) in the Americas dates back 8,000–10,750 years BP, making it the earliest domesticated crop in the region, preceding maize and beans by around 4,000 years. Evidence of this domestication was found in Guilá Naquitz Cave and four other Mexican caves during excavations in the 1960s, possibly starting in 1959.
Archaeological Significance
- Guilá Naquitz Cave provides direct evidence of the domestication of plant species in this region, which played a significant role in the development of Mesoamerican agricultural systems.
- The findings indicate that the early inhabitants combined foraging with the early stages of agriculture, transitioning gradually from a nomadic lifestyle to a more settled, agricultural existence.
- The discovery of charred squash seeds and pollen also provided crucial data on the climatic and environmental conditions of the Oaxaca Valley during this time.
Excavation History
Early Investigations
- Richard S. MacNeish, an American archaeologist, led the primary excavation at Guilá Naquitz Cave in 1966. MacNeish’s research aimed to uncover the origins of agriculture in the Americas, and his work at this cave yielded pivotal evidence.
Methods and Techniques
- Excavations involved stratigraphic analysis, allowing researchers to carefully map out the different layers of occupation over time. This method helped determine the chronology of the domestication process for different plants.
- Radiocarbon dating was extensively used to estimate the age of seeds and other organic remains, providing accurate timelines for the domestication of various crops.
Stratigraphy and Occupation
- The cave contained well-preserved layers of material that documented repeated seasonal occupations by early humans. The stratigraphy allowed researchers to identify different phases of habitation, each characterized by a distinct set of activities, such as hunting, gathering, and early farming.
Significance to Mesoamerican Agriculture
- Guilá Naquitz Cave stands as a key site for understanding the origins of agriculture in Mesoamerica. The domestication of plants like squash and maize laid the foundation for the later development of complex societies, such as the Zapotec and the Maya.
- The site shows that early agriculture in Mesoamerica was not an abrupt change but a gradual process of experimentation, leading to the development of staple crops that would sustain burgeoning civilizations.
This cave provides a rare glimpse into the early adaptive strategies of hunter-gatherers transitioning into settled agricultural communities in the Oaxaca Valley, marking it as an important site for understanding the origins of human agriculture and society in the Americas.
