A Multispecies Perspective Into Dietary Genetic Adaptations And Ancient Migration In The Peruvian Andes, Kelsey Jorgensen
A Multispecies Perspective Into Dietary Genetic Adaptations And Ancient Migration In The Peruvian Andes, Kelsey Jorgensen
Wayne State University Dissertations
Successful adaptation to the high-elevation Andes would have required both cultural and biological adaptations by early human populations. These past adaptations continue to shape the evolutionary outcomes of both humans and non-human species today. A multispecies perspective was used to examine how humans and non-human creatures, specifically insects, were shaped by past human adaptations. This dissertation asked two primary questions: 1) Given the importance and evolutionary history of potato consumption in the Peruvian Andes, is a genetic adaptation to better digest potato starch detectable in present-day Peruvians? and 2) Using the Andean Potato Weevil (APW) phylogeny as a proxy, what …

Effect Of Recent Historical Events On Migration And Isonymic Stratification Among The Rama Amerindians From Nicaragua, Norberto F. Baldi
Human Biology Open Access Pre-Prints
The Rama Amerindians from southern Nicaragua are one of few indigenous populations inhabiting the east coast and lowlands of southern Central America. Early 18th century ethnohistorical accounts depicted the Rama as a mobile hunter-gatherer and horticulturalists group dispersed in household units along southern Nicaraguan rivers. However, during the 19th and 20th centuries, Rama settlement patterns changed to aggregated communities due to increased competition for local resources resulting from non-indigenous immigration. This study’s objective was to discern the degree of relatedness between and within subdivisions of seven of these communities based on patterns of surname variation and genealogical data. We applied …
