The Conquest Of Milk: The Rise Of Lactase Persistence And The Fall Of Scandinavian Hunter-Gatherers, Nicholas Mays
The Conquest Of Milk: The Rise Of Lactase Persistence And The Fall Of Scandinavian Hunter-Gatherers, Nicholas Mays
James Madison Undergraduate Research Journal (JMURJ)
Over half of the global human population suffers from lactase nonpersistence, a condition marked by losing the ability to digest lactose after infancy. However, a minority of the global population, primarily located in Central and Northern Europe, has a genetic mutation that results in lactase persistence, which is the continued ability to process lactose after infancy. This interdisciplinary analysis blends archaeology, cultural anthropology, evolutionary biology, and archaeogenetics to explore the origin and rise of lactase persistence in Europe and its contribution to the end of hunter-gatherer societies in Scandinavia. Furthermore, the paper uses gene-culture coevolutionary theory to argue that lactase …
Genetic Impacts Of Deforestation On Mouse Lemurs, Darice Westphal
Genetic Impacts Of Deforestation On Mouse Lemurs, Darice Westphal
Dissertations, Theses, and Capstone Projects
The impact of deforestation on the genetic structure of mouse lemurs is poorly understood. In this project, I assess deforestation of Madagascar’s terrestrial protected regions, quantify genomic wide genetic variation in two sympatric mouse lemurs, and evaluate the role of landscape structure in genetic relatedness patterns within two sympatric mouse lemur species. Overall deforestation rates across the 98 terrestrial protected areas in Madagascar are increasing, resulting in an average annual deforestation rate of 0.68% per year, with approximately 10,600 km2 lost between 2000 and 2019. In a comparison of relatedness patterns between the sympatric gray mouse lemur (Microcebus …
