Food And Diet In The Andes: Changing Markets And Lives In Nuñoa, James A. Fisher
Food And Diet In The Andes: Changing Markets And Lives In Nuñoa, James A. Fisher
Masters Theses
The town of Nuñoa, located in the southern Peruvian Andes, has been the ongoing focus of anthropological research. Household surveys of diet and food security (n=69) administered during 2012 are analyzed here and compared to past studies from previous decades. Study results show clearly that the amount and diversity of new foods available in the area has increased dramatically, but also gives evidence for continued disparate access to certain types of food along class lines. Socioeconomic status had a significant negative correlation with food insecurity and poor households more frequently consumed both potatoes and other cheap, high carbohydrate foods such …
Human Feeding Biomechanics : Intraspecific Variation And Evolution, Justin Ledogar
Human Feeding Biomechanics : Intraspecific Variation And Evolution, Justin Ledogar
Legacy Theses & Dissertations (2009 - 2024)
This study examines feeding biomechanics in modern human crania and those of extinct early members of the human lineage in order to better understand the selective pressures that influenced human craniofacial evolution. Specifically, this study uses finite element analysis to examine: 1) human feeding performance, in terms bite force production and craniofacial strength; 2) intraspecific variation in human feeding biomechanics; 3) feeding biomechanics in fossil hominins, including Australopithecus sediba and Homo habilis, species that are potentially at the root of modern human lineage, and 4) the functional role of purported facial buttresses.
