Modern agricultural systems have been criticized for their detrimental effects on the environment and a general emphasis on crop yield rather than long-term sustainability. Traditional forms of agriculture may provide case-specific examples of sustainable alternatives for contemporary societies.

Show moreModern agricultural systems have been criticized for their detrimental effects on the environment and a general emphasis on crop yield rather than long-term sustainability. Traditional forms of agriculture may provide case-specific examples of sustainable alternatives for contemporary societies. In the seasonally inundated savannas of the Llanos de Mojos, pre-Columbian Indians piled earth into 'large raised field platforms' elevated high enough above the floodplain to allow crops to grow. Archaeological evidence indicates that raised field agriculture supported much larger populations than those found in the Beni today. The examination of satellite imagery has revealed more than 40,000 individual fields spread across an area of approximately 7,500 square kilometers. This study created a digitized map of large raised fields to search for spatial patterns in their distribution. A GIS analysis was conducted in which fields were distributed into organizational groups based on characteristics such as proximity and orientation to cardinal direction. These groups represent potential 'social units' involved in the organization of labor required to construct raised fields. This study demonstrated the consistent presence of these units throughout the entirety of the agricultural system. Patterns in the distribution of these groups allowed the study area to be divided into two distinct regions representing a larger scale of organization within a seemingly uniform system. A transitional zone between these two regions was identified on the river Omi, providing a clear area of interest to target in future archaeological excavations. Further archaeological investigations of raised field agriculture have the potential of demonstrating the overall productivity of the system as well as how it was incorporated into the social systems of those who managed it.

Show moreArchaeologists have pored over countless texts of the ancient civilizations, attempting to piece together bygone worlds. However, relatively little work has been done to reconstruct the musical history of these societies, and even less on why their musical histories are important. This paper aims at a synthesis between the ancient Egyptian and classical Greek archaeological records to analyze the importance of music in Paleolithic human cognitive development. Countless musical instruments have been discovered globally, ranging from pre-Columbian bone flutes in Oaxaca, Mexico to ancient trumpets in Egyptian burials (Barber et al 2009). Apart from their place in a museum, minimal work has been done to ascertain their importance to human society as a whole. This thesis attempts to display the crucial need for more research in this field. The recent decline in support for arts education in favor of 'hard sciences' and mathematics is deeply disturbing; the history of humanity should be important not only to anthropologists and historians, but to members of all disciplines. This lack of interest in 'soft sciences' and the arts may lead to a complete loss of ancient musical history; a loss that would be devastating to history, anthropology and the worlds. The contents of this paper portray both the ancient importance of music, and how it contributed to increased cognitive faculties during hominid development.

Show moreThe archaeological record of the Iroquois supports that settlements were regularly relocated during the protohistoric period (1500-1650 A.D.). With the use of Geographic Information Systems (GIS) computer software, archaeologists may analyze variables potentially resulting in or influencing the movement of settlements. Through the use of spatial analysis, I argue that Cayuga Iroquois settlement locations were influenced by the environmental characteristics of their surrounding landscape. Specifically, wetlands are believed to have influenced settlement location choices in central New York state. This study examines the spatial relationships between wetland habitats and protohistoric period Cayuga Iroquois settlements where swidden maize agriculture comprised most of the diet. Considering previous research that has linked the movement of settlements to Iroquois agricultural practices, I hypothesize that wetlands played a significant role in the Iroquois subsistence system by providing supplementary plant and animal resources to a diet primarily characterized by maize consumption, and thereby influenced the strategy behind settlement relocation. Nine Cayuga Iroquois settlements dating to the protohistoric period were selected for analysis using GIS. Two control groups, each consisting of nine random points, were generated for comparison. Distance buffers show the amount of wetlands that are situated within 1-, 2.5-, and 5-kilometers from Cayuga settlements and random points. The total number of wetlands within proximity of these distances to the settlements and random points are recorded and analyzed. The results indicate a statistical significance regarding the prominence of wetlands within the landscape which pertains to the Cayuga Iroquois settlement strategy.

Show moreMore rigorous methodological protocols are needed to document outdoor forensic scenes containing skeletal remains. However, law enforcement protocols rarely provide specific guidelines for processing these scenes. Regardless, the need to preserve contextual information at crime scenes is of paramount importance and it is worth exploring new technological applications that will allow for better documentation. Close-range photogrammetry (CRP) is one option for outdoor scene documentation, more prominently utilized in archaeological contexts, that may provide forensic archaeologists with a tool to better document these scenarios via 3D modeling. To test the efficacy of CRP as documentation tool three mock scenarios representing common outdoor scenes were created using faux osteological material: a close scatter of osteological remains in a pine flatwood setting, a wide scatter of osteological remains in the same setting, and the partial excavation of skeletonized remains. Images were collected using a digital camera and processed using Agisoft Photoscan Professional. A series of variables were tested in successive iterations of data capture for each scenario to determine best practices for overall accuracy: camera images captured by hand versus fixed to a tripod, scale bar positioning, and number of images captured. Accuracy was determined via final root mean square error values and through a comparison between real-world to virtual measurements. Results show that CRP is a cost and time-effective method of documenting contextual data at a scene via the creation of 3D models and scaled orthomosaic images. This method is most useful for the documentation of excavations owing to the controlled and contrasted sub-surface in comparison to the subject material. The two scatter scenarios offered additional challenges due to the complexity of the ground covering, however models nonetheless provided accurate contextual detail and errors may be mitigated through proper data capture. There was little difference in the variables for image capture, scale bar placement, or number of images. Instead, the quality of images, image capture method, and post-processing operations proved to be more important. Due to the ease of use and the ability to convey best practices for data capture, the utilization of CRP for outdoor scene documentation is recommended as a valuable addition to current forensic documentation protocols. Future research should focus on the utilization of actual osteological material as a proxy for forensic scenarios as well as study the applicability of CRP to assist in documenting taphonomic modifications.

Show moreWhile side-scan sonar has become a valuable geophysical tool for forensic water searches, controlled research is paramount to determine the best practices for searches in aquatic environments as it provides a structured environment in which to investigate variables that influence the effectiveness of the technology and provides valuable experience for sonar operators. The purpose of this research is to conduct controlled research in order to evaluate the applicability of side-scan sonar to searches involving submerged firearms and proxy cadavers. In addition, the best practices for employing this technology in forensic searches in freshwater ponds and lakes in a humid, subtropical environment in Central Florida would be developed. Five street-level firearms were submerged in a pond, and two sets of three pig carcasses (Sus scrofa), utilized as proxies for human bodies, were staked to the bottom of a pond for this research. Transects were conducted over the firearms and the pig carcasses utilizing side-scan sonar. The first set of pig carcasses represented a child size (30-32 kg) and the second set a small adult size (51-54 kg). Results show that firearms were not detected due to the terrain and small size. However, this technology successfully located small to medium-sized proxy carcasses on a flat, sandy lake bottom when experienced operators were conducting the search. Conversely, vegetation obscured submerged bodies. While the smaller carcasses were difficult to detect throughout the data collection, medium-sized carcasses were easily discerned. Moreover, the medium-sized carcasses decomposed at the same rate as previous studies and were visible throughout each stage of decomposition. Finally, employing a 900 kHz frequency with a 20 m swath-width provided the best search parameters. Therefore, in the appropriate conditions,side-scan sonar is an effective tool for locating submerged bodies in freshwater lakes and ponds in a humid, subtropical environment.

Show moreDiversity of Chachapoya mortuary practices is not well understood archaeologically, even though the region has received some attention for the monumental constructions and visually striking mortuary complexes located high on open cliff faces. This may be due to the difficult accessibility and often poor state of preservation consistent with many Chachapoya mortuary and occupation sites. This thesis reconstructs mortuary practices at La Petaca in the Chachapoyas region of Peru, applying paleodemographic and GIS methodological approaches to facilitate and improve the bioarchaeological study of commingled skeletal remains in an open, disturbed communal funerary context. Research focused on SUP CF-01, a natural cave context utilized as a group burial. The sample of human remains retrieved from SUP CF-01 (n= 8182) estimated an MNI of 43 adults and 12 juveniles, including a range of demographic categories. By employing a total station to record the cave structure, and a GIS to analyze the deposit of commingled remains, this thesis was able to measure the distances between paired elements and to explore possible post-depositional practices that could have created this commingled and disturbed deposit. This bioarchaeological analysis incorporating demographic and spatial analysis indicated that this collective burial was a primary context, and most likely a result of a gradual accumulation of complete bodies and movement of later skeletonized elements to make room for successive burials. When compared to other mortuary contexts at this complex, including a comparative secondary cave context and over 120 constructed mausoleums, it appears that all community members were included in the mortuary practices at this complex.

Show moreTo accurately describe the past, historians strive to learn the cultural ideologies of the time and place they study so their interpretations are situated in the context of that period and not in the present. This exploration of historical context becomes critical when researching marginalized groups, as evidence of their rhetorics and cultural logics are usually submerged within those of the dominant society. This project focuses on how factors, such as rhetor/audience perspective, influence cross-cultural historical interpretation, and how a community history database can be designed to illuminate and affect these factors. Theories of contact zones and rhetorical listening were explored to determine their applicability both to history-making and to the creation of a community history database where cross-cultural, multi-vocal, historical narratives may be created, encountered, and extended. Contact zones are dynamic spaces where changing connections, accommodations, negotiations, and power struggles occur, and this concept can be applied to history-making, especially histories of marginalized groups. Rhetorical listening focuses on how perspective influences understanding the past, and listening principles are crucial to both historians and the consumers of history. Perspectives are grounded in cultural ideologies, and rhetorical listening focuses on how tropes, such as race and gender, describe and shape these perspectives. Becoming aware of tropes(-)both of self and other(-)can bring to view the commonalities and differences between cultures, and allow a better opportunity for cross-cultural understanding. Rhetorical listening steers the historian and the consumer of history towards looking at who is writing the history, and how both the rhetor and the audience's perspective may affect the outcome. These theories of contact zones and rhetorical listening influenced the design of the project database and website by bringing perspective to the forefront. The visualization of rhetor/audience tropes in conjunction with the co-creation of history were designed to help foster cross-cultural understanding.

Show moreScene mapping is an integral part of processing a forensic scene with scattered human remains. By utilizing the appropriate mapping technique, investigators can accurately document the location of human remains and maintain a precise geospatial record of this evidence at a scene. Global positioning system (GPS) units have been used for years to survey the spatial distribution of large-scale archaeological sites. However, differential global positioning (DGPS) unit now provide decreased positional error suitable for small-scale surveys, such as forensic scenes. Because of the lack of knowledge concerning this utility in mapping a scene, controlled research is necessary to determine the practicality of using DGPS in mapping scattered human remains in different environments. The purpose of this research is to quantify the accuracy of a DGPS unit for mapping skeletal dispersals and to determine the applicability of this utility in mapping dispersed remains. First, the accuracy of the DGPS unit was determined using known survey markers in different environments. Secondly, several simulated scenes were constructed and mapped in open, tree-covered, and structure-obstructed environments using the DGPS. Factors considered included the extent of the dispersal, data collection time, and the use of offsets. Data were differentially postprocessed and compared in a geographic information system (GIS) to evaluate the most efficient recordation methods. Results of this study show that the DGPS is a viable option for mapping human remains in open areas. Furthermore, guidelines for accurate scene mapping using a DGPS unit will be provided, along with a discussion concerning the integration of DGPS into GIS for scene analysis and presentation.

Show moreStable isotope analysis is often used to evaluate elements of the lives of past peoples, such as diet and health status, at a societal level. Analysis at an individual level is exceptionally rare, and has not been conducted using a variety of tissues representing both early life and life approximate to death. In this study, ?13C and ?15N isotope signatures are used to create life histories for single individuals from Romano-Christian period Kellis 2 cemetery in the Dakhleh Oasis, Egypt. Samples are obtained from several different tissues, including tooth dentin, bone collagen, hair, nail, skin, and gut content, all of which have been previously researched, but have not been studied at such an individualistic level. By using data and previous research conducted by Drs. Tosha Dupras and Lana Williams, this research uses isotopic values from the aforementioned tissues, and the differing turnover rates of these tissues, to develop lifetime timetables for 15 individuals (female, male, and juvenile). Results show that individual analysis is possible, informative, and can enlighten researchers not just concerning the individual, but about the population as a whole. The methods presented can serve as a model for reconstructing individual life histories using isotope data from multiple tissues.

Show more(")From the Temple to the Synagogue(") is an analysis on the influence of external cultures, predominantly the Persian religion of Zoroastrianism on the early rabbis following their failed revolt against Rome and the destruction of the Second Temple in the first century CE. How did the Jewish people react to the upheaval of their center of worship? What can we attribute to the major changes in their religious literature and centers of worship following the demise of their rebellion? Is it possible that what has traditionally been seen as an isolated and uniform group of people did in fact borrow major theological ideas from neighboring religions? This analysis demonstrates the transmission of ideas into this new center of power in the Jewish community, that of the rabbis, through their changed notions of the afterlife, the incorporation of artistic design within the synagogue, and the apocalyptic literature of the Dead Sea Scrolls community of Qumran. While the conversation has become more open in recent years to the idea that Judaism did not simply grow in a bubble, the extent to which Persian ideas made their way into Jewish theology has been largely ignored. This work seeks to demonstrate how open early rabbinic Judaism was to the exchange of ideas and how much of their ideas can be attributed to their non-Jewish neighbors.

Show moreSlip, a fluid suspension of clay that is applied to the surface of a piece of ceramic, allows for increased control over the functional and aesthetic properties of a finished vessel. The potter can select a slip to provide a more appealing color, texture, and/or luster to the vessel's surface, while maintaining the favorable functional qualities of the paste. Though slip color has long been used as an attribute for classification in the Maya lowlands, only recently have the raw materials of slips been used to inform studies of production and exchange, with much of this work using Late and Terminal Classic-period ceramics and analysis techniques that require taking small samples of each ceramic to be analyzed. Such studies present an incomplete picture of Maya slips, since they only include later ceramics and exclude vessels from which samples cannot be taken. This thesis broadens our understanding of Maya slips by 1) establishing portable x-ray fluorescence (pXRF) spectrometry as a nondestructive analysis technique that can be used to chemically characterize slips on a wide range of sherd sizes and whole vessels, and 2) determining the chemical compositions of red, cream, and black slips on Middle and Late Preclassic-period ceramic sherds excavated in 2017 from Holtun, Guatemala. The data produced through pXRF spectrometry revealed that red slips were chemically distinct from the other two colors, while white and black slips were chemically indistinct. Iron, zinc, molybdenum, tin, and antimony concentrations were the principal determinants of compositional groups. These results indicate that these elements are of primary interest in sourcing the clays used to make the slips, and trends in the chemical composition of each color have the potential to reveal much about Maya potters' processes and standardization in slip production.

Show moreThis dissertation addresses the problem of human action detection, human tracking and segmentation in videos. They are fundamental tasks in computer vision and are extremely challenging to solve in realistic videos. We first propose a novel approach for action detection by exploring the generalization of deformable part models from 2D images to 3D spatiotemporal volumes. By focusing on the most distinctive parts of each action, our models adapt to intra-class variation and show robustness to clutter. This approach deals with detecting action performed by a single person. When there are multiple humans in the scene, humans need to be segmented and tracked from frame to frame before action recognition can be performed. Next, we propose a novel approach for multiple object tracking (MOT) by formulating detection and data association in one framework. Our method allows us to overcome the confinements of data association based MOT approaches, where the performance is dependent on the object detection results provided at input level. We show that automatically detecting and tracking targets in a single framework can help resolve the ambiguities due to frequent occlusion and heavy articulation of targets. In this tracker, targets are represented by bounding boxes, which is a coarse representation. However, pixel-wise object segmentation provides fine level information, which is desirable for later tasks. Finally, we propose a tracker that simultaneously solves three main problems: detection, data association and segmentation. This is especially important because the output of each of those three problems are highly correlated and the solution of one can greatly help improve the others. The proposed approach achieves more accurate segmentation results and also helps better resolve typical difficulties in multiple target tracking, such as occlusion, ID-switch and track drifting.

Show moreThis project takes the Iron Age tumuli of the Kanak Su Basin in Yozgat, Turkey as a case study for the application of geospatial methods to reconstruct past perceptions of a mortuary landscape. The tumulus fields (-) landscapes heavily modified by monumental burial mounds (-) of central Anatolia present an opportunity to investigate how burial practices reflect and create places of collective memory, territorial identity, and the social order. Understanding the nature of Iron Age settlement in the Kanak Su Basin remains an ongoing subject of study in central Anatolian archaeology, especially in regard to how the large, short-lived city of Kerkenes interacted with the existing long-term settlement history in the basin. This project seeks to understand the role of the tumuli in this landscape by investigating the relationship between the settlement pattern and the burial mounds along axes of proximity, visibility, and accessibility using spatial statistics, viewsheds, and least cost pathways. The spatial distribution of mounds suggests which sites might have participated in constructing tumuli and the possible motivating factors in their location. Larger sites in the study area appear to have participated more frequently in tumulus construction. This analysis also allows us to reconstruct the more general experience of living among the mounds, whether one participated in the practice or not, and results suggest the tumuli were located to increase the number of people who perceived and interacted with them.

Show moreUnderstanding human response to natural disasters is a core problem for environmental archaeologists. Hurricanes are often devastating to coastal populations, and recognizing behavioral change in response to these major storm events provides context for the resilience and adaptability of ancient coastal people. This research project focuses on retrodicting periods of increased storm frequency and intensity for regions of the Florida coast and comparing those storm periods to the existing archaeological record in order to determine if there are correlations between increased storminess and periods of site abandonment and/or changes in subsistence strategy. These potential correlations may aid in our understanding of human cultural response to dramatic environmental change. Particle size analysis was performed on sediment cores collected from 5 coastal Florida lakes in order to determine periods of increased storm occurrence dating back as far as 9000 B.P. After comparing these storm chronologies to dated materials from the existing archaeological record of the regions surrounding each of the coastal lakes, preliminary analysis shows the potential for correlation between periods of increased storminess and site abandonment. At the regional level and in several intra-site comparisons, there are some noticeable staggering effects between the periods of storminess and the radiocarbon dates of archaeological materials. Further investigation is needed to more fully understand the relationship between these two datasets, which may further our understanding of cultural resilience to environmental stressors and the catalyzing forces of site abandonment and subsistence change in coastal Florida.

Show moreThis study aims to determine whether there are any differences in the burial practices for non-adults and adults at the Late Bronze Age site of Tell el-Far'ah (South) in modern day Israel. The archaeology of childhood together with various methods of analyses, including geospatial and statistical techniques, were utilized to address the main research question focused on the spatial differences and relationships between non-adult and adult burials. There are missing children in the archeological record. Tell el-Far'ah (South) is an example of this phenomenon. Reasons vary from taphonomy to potential infanticide. Based on the currently available data, it seems that the people of Tell el-Far'ah (South) understood non-adults as both similar to and dissimilar from adults. In sum, this is not a comprehensive or conclusive study, but rather serves to shed light on the lack of attention in the archaeology of childhood and more generally on the need for greater integration of the anthropological subfields.

The Llanos de Mojos, a region of the southwestern Amazon, is a seasonally flooded savannah located in the Beni department of Bolivia. The area sustained a significant pre-Columbian population up to the arrival of Jesuit missionaries in the late 17th century. Local communities constructed agricultural landscape modifications to help cultivate crops such as maize, manioc, and sweet potato. Raised fields contributed to soil nutrient intensification and helped to manage flooding. This study...
Show moreThe Llanos de Mojos, a region of the southwestern Amazon, is a seasonally flooded savannah located in the Beni department of Bolivia. The area sustained a significant pre-Columbian population up to the arrival of Jesuit missionaries in the late 17th century. Local communities constructed agricultural landscape modifications to help cultivate crops such as maize, manioc, and sweet potato. Raised fields contributed to soil nutrient intensification and helped to manage flooding. This study examines the relationship between 40,766 raised agricultural fields which were digitized by the Proyecto SIG Arqueol(&)#243;gico del Beni using Google Earth and maps of surface flood coverage. Flood maps from 2012(-)2016 were analyzed using 14-day aggregates of Moderate Resolution Imaging Spectroradiometer (MODIS) data provided by the Dartmouth Flood Observatory. These datasets were compared using ArcGIS to examine the extent and variability of yearly flooding as well as the number of raised fields which were subject to seasonal inundation on a year-by-year basis. It was found that despite significant portions of the region being covered by seasonal floods, only 5.79% of the fields were exposed to flooding in total. This study concluded that raised fields were more suited to the containment and dispersion of localized precipitation rather than the dispersion of riverine flooding. Several fields that have paleobotanical associations with maize, manioc, and sweet potato cultivation only experience flooding for 1 out of the 5 years analyzed, supporting their practicality for growing water-sensitive crops.

Show moreFrom its establishment by royal decree in 1610 until its abolition in 1821, the Inquisition tribunal of Cartagena de Indias sought to stamp out heresy and maintain Catholic orthodoxy among the inhabitants of the territory of New Granada. This thesis examines the activities of the tribunal during the first half of the seventeenth century, specifically as they relate to its persecution of the crypto-Jews under its jurisdiction. While the surviving evidence demonstrates a significant crypto-Jewish presence in Cartagena in the 1600s, and even though the authority of this tribunal extended far beyond its immediate surroundings, very few crypto-Jews were ever prosecuted by this court during this time. This thesis explores the social, economic and political dynamics explaining a change in policy that led to a rise in the number of Inquisition trials against the crypto-Jewish population in the first half of the seventeenth century. This thesis argues that Spanish imperial politics coupled with socio-economic factors inherent in the colonial system, explains why inquisitorial persecution increased in this period.

Show moreNigeria's petroleum industry is the lynchpin of its economy. While oil has been the source of immense wealth for the nation, that wealth has come at a cost. Nigeria's main oil-producing region of the Niger River Delta has experienced tremendous environmental degradation as a result of decades of oil exploration and production. Although there have been numerous historical works on Nigeria's oil industry, there have been no in-depth analyses of the historical roots of environmental degradation over the full range of time from the colonial period to the present. This thesis contends that the environmental degradation of Nigeria's oil producing region of the Niger Delta is the direct result of the persistent non-implementation of regulatory policies by post-independence Nigerian governments working in collusion with oil multinationals. Additionally, the environmental neglect of Nigeria's primary oil-producing region is directly traceable back to the time of colonial rule. Vital to this argument is the view that the British colonial state created the economic institutions which promoted Nigerian economic dependency after independence was achieved in 1960. The weakness of Nigeria's post-colonial dependent system is exposed presently through the continued neglect of regulatory policies by successive post-colonial Nigerian governments.

Most settlement pattern research and GIS analysis of the ancient Maya of the Northern Yucatan have focused on water availability in a dry landscape where cenotes are often the only water source. While water is of paramount importance, permanent settlement secondarily requires farmable soil, a resource often as precious as water in many parts of the Yucatan. The dynamics between these resources reveal areas of ideal settlement and more challenging landscapes for which the Maya developed...
Show moreMost settlement pattern research and GIS analysis of the ancient Maya of the Northern Yucatan have focused on water availability in a dry landscape where cenotes are often the only water source. While water is of paramount importance, permanent settlement secondarily requires farmable soil, a resource often as precious as water in many parts of the Yucatan. The dynamics between these resources reveal areas of ideal settlement and more challenging landscapes for which the Maya developed strategies to overcome environmental conditions. A region of the southwest "Cenote Zone", however, appears to have presented the ancient Maya with insurmountably poor environmental conditions despite abundant water resources. The lack of dense population and stone architecture in this area emphasizes the lack of a simple correlation between cenotes and settlement. This thesis uses GIS analysis to identify and explore such problematic settlement areas to better understand the factors and complexities involved in the more successful settlements of neighboring regions.

Show moreThe Muisca people of the Eastern Cordillera of Colombia had an exceptionally complex diet, which is the result of specific subsistence strategies, environmental advantages, and social restrictions. The distinct varieties of microclimates, caused by the sharp elevations in this part of the Andes, allows for a great biodiversity of plants and animals that was accessible to the native population. The crops of domesticated and adopted plants of the Muisca include a wide variety of tubers, cereals, fruits, and leaves that are described in detail in this thesis. The Muisca used an agricultural method known as microverticality where the different thermic floors are utilized to grow an impressive variety of species at various elevations and climates. This group also domesticated the guinea pig, controlled deer populations and possibly practiced pisiculture, patterns that are also described in this text. Some of the foods of the Muisca were restricted to specific social groups, such as the consumption of deer and maize by the chiefly classes and the consumption of roots and tubers by the lower class, hence the complexity of their dietary practices. The utensils utilized in the preparation and processing of foods, including ceramics and stone tools were once of extreme importance in the evolution of the Muisca diet and form an important part of this research as well as the culinary methods that are described in the Spanish chronicles and by contemporary experts. The majority of food products utilized by the Muisca in antiquity are still part of the diet of contemporary Colombians and the current uses of these foods can allow us to understand how these products were used by this pre-Columbian society. On the other hand, knowledge of the practices used by the Muisca can facilitate the preservation of these foods in the modern diet and avoid the introduction and replacement of these foods by non-native products, which can be less nutritious.
